You COULD Go Over the Side -- Really! -- Lifelines

No smart cracks this time -- this is serious stuff

I have heard about lifelines from a couple of people ever since I got my first little sailboat. People are passionate in their beliefs about them.

For instance, there's a big debate about whether they should be clad in vinyl or not. Many owners feel the vinyl looks nicer, even though vinyl-clad cable is more expensive than bare cable. Others insist that it's extremely important to have bare cable, because vinyl can hide the first signs of rust, a sign that your lifelines could fail.

Oh my gracious -- then you could fall overboard, right?

Well, yeah, you CAN fall overboard, but it can happen if you have the newest, brighest, tightest lifelines possible.

How is that possible?

Just go stand on the side of your boat, and note where the lifeline touches your body. Unless you're a child, it's going to be WELL below your waist. This means that your center of gravity is WELL above that top lifeline (assuming you have two -- smaller boats will only have one). 

The lifelines can't save you, I don't care what the "experts" say. I know a true expert who calls loose or weakened lifelines "deathlines." He's been sailing for many, many years and figured out long ago that the lifelines won't save him, but it's hard to ignore that word -- LIFEline.

Well, you have to. Words don't trump the laws of physics.

So what are they good for? They're an OUTSTANDING visual guide. They make it very, very clear where the edge of the cliff is. But once you have realized that those lifelines won't save you (and could actually encourage you to topple over), you'll realize why you want to move toward the bow from the HIGH side of the boat. On the high side of the boat, if you do fall, you'll fall toward the center of the boat -- not into the water.

What else can you do? My boat is 100% netted. I even made a frame with netting on it that lashes to my gates when they're closed. I have a coordination problem (talked about in a much earlier post), so I'm more likely than you to go over the side. Not everyone wants netting but I think it's wise for me.

The other thing you *must* do is make sure you have good handholds along the edge of your cabin top. You often see these made of teak. My boat also has a stainless steel grab bar that runs across the beam. We hear the saying, "One hand for yourself and one for your boat," and that's exactly what it means. As you move forward, you should always be holding on with one hand, and you shouldn't be holding the lifeline. You should be holding something closer to the center of the boat.

If the boat is sailing and you need to do something at the mast, move to the mast from the high side of the boat, where gravity will tend to push you toward the boat, not away from it.

Wear nonskid shoes. I don't care how many macho men tell you bare feet are best: if you break a toe, you're going to be significantly hobbled. Test their grip on your deck periodically, as the grip-holding tendencies of your shoes can wear out.

Don't count on the "life" lines to save you. Do keep them in good shape, but they are last-ditch, and in my opinion, best used by attaching netting to them.

Sailing in Gusty Winds -- a great link!

People who have sailed for many years mostly know this information, but this blog is for people with less experience, and one of the more challenging situations for newer sailors is when the weather turns gusty. You could be unexpectedly caught in gusty weather for a number of reasons. You might have expected to get back in long before the bad weather hit, but something goes wrong and you don't make it.

You need to know how to handle gusty weather. Not only will you and your companions be uncomfortable otherwise -- someone could be hurt. They could be moving toward the head when a gust hits and fall in the cabin (fall in the cabin and you're very likely to have a bad fall), or sprain something when thrown off balance, or be hurt while moving forward to deal with something.

The webpage listed below covers what to do extremely well. I'll just make a few comments in case the information doesn't quite make sense. Here's the website:

http://learntosail.hubpages.com/hub/Three-Sailing-Tips-for-Less-Heel-in-Gusty-Breezes

And here's the core, with my comments in blue:

"1. Luff up on a Gust
Watch the water to windward. Look for dark, ruffled spots that signal the arrival of a gust. Point up toward the wind just before the gust arrives. This will luff the forward part of your sails and depower them--but keep the boat driving and on her feet!"

 Start learning to read the surface of the water now. The surface does change as the wind changes. On a light wind day, you can see puffs of stronger wind coming to take advantage of them. On rough days, you can see them coming and strategize.

So what does "luff up" mean? It means to make the sales "luff," or shake. It typically (but not always) starts at the luff, or leading edge, of the sail. You make the sail luff by steering more directly into the wind. A sailboat pointing into the wind can't sail because it can't catch any wind, and it can't use the sails as an air foil. The boat is depowered, which is what you need in too much wind. You need to depower the sails. This is one way to do it, and if the gusts are significant, you need to be in position before the gust hits.

You can also steer into the wind as you feel the wind rising. Gusts often occur on a curve -- the first increase will not be the peak, and you still have time to ease its impact on your boat, but also learn to read the waves.

What does "still driving the boat" mean? The writer is suggesting that you don't point the boat completely into the wind -- just enough to weaken the effects of wind on your sail. You're still moving, and the boat is "on her feet" -- not heeling excessively.

So what this is really about is steering. Now, steering is easier when the boat is in balance, which is covered a little further below.

"2. Ease your Sheets / Back your Blocks
Move the mainsheet car down the traveler track to leeward. Ease the mainsheet a few inches. Then, set your headsail sheet blocks back a few holes along the Genoa tracks. These actions cause the top of your sail to open--or twist--to spill high octane wind up high. This keeps heel down for a more balanced boat."

What's the "mainsheet car?" I could show you a picture of mine, but yours might look different. The "traveler track" moves across the beam of the boat. Sometimes it's across the cabin top, as mine is. Sometimes it's in the floor of the cockpit, right in front of the companionway. Sometimes it's at the back of the boat. Some smaller boats don't have travelers -- my little 25' Irwin didn't have one.

If you have a traveler, you release both traveler lines, and then pull on the leeward line. If the wind is coming over your port side, you pull on the starboard traveler line, and move the sail controls to starboard. This causes "twist" at the top of the sail. You can spot this because the curve of the leech -- the back edge of the sail -- will now have a more exaggerated curve in it, especially toward the top. This makes the sail more inefficient. It's an easy and quick way to depower your mainsail. If the gust was significant enough to make your boat heel too much, she should immediately settle down and heel less, what the author means by "keeping heel down."

But what does a "more balanced boat" mean? Without getting technical, the more balanced the boat is, the less physical exertion it takes to steer the boat. But it *also* means that the boat is more in control. Using the traveler to move the sail to leeward is a quick and effective method to "spill the mainsail" so it can't hold as much wind. You have effectively, temporarily turned your mainsail into a smaller sail.

OK, so what does "back your blocks" mean? The sheets for your headsail come back to the cockpit after being led through a moveable block that sits on a long track. The position of that block can dramatically affect the shape of your headsail. When the winds pick up, adjusting your mainsail as described above may not be enough to get your boat back in balance and sailing easily (which you judge easily by the amount of effort needed to steer her). If you move those blocks back toward the stern, you ... twist the headsail as well, causing wind to spill out of the top, and in effect, making your headsail smaller. 

Now, this isn't as easily (or as safely) done as adjusting the traveler. To move the blocks you have to first notice where the load is. Which is the working sheet? Well, in the scenario above, the wind was coming across the port side of the boat (a "port tack"). This makes the STARBOARD sheet carry the load. The port sheet is slack. So that's the one to adjust first, even though it won't change the sail. Slide it back as much as you think you need. Now, if you've gone out and practiced, you'll be able to make an educated guess. If you haven't practiced that yet, then your rule of thumb might be -- the stronger the gusts are, the more you should move it back.

Now you have to move the loaded block, and that can be more dangerous. You have two choices.

First choice is to switch to a starboard tack. The problem with that choice is that tacking isn't a lot of fun in rough water and winds that are overpowering your boat. It's not impossible, but make sure there's no one in the cabin and that everyone is secure (they do have PFD's on, right?) After the tack, your starboard sheet will be the "lazy" sheet and you can move the block toward the stern easily.

If tacking seems like a bad idea (whoever works the sheet is going to have to pull hard and fast on the new working line, and the helmsman should watch his or her progress, and not complete the turn until the new working sheet is under control and tight enough), here is how to move the block while the sheet is under load:

Always remember: ONE HAND FOR YOU AND ONE FOR THE BOAT. Don't use both hands doing this in rough water. 

Step firmly on the working jib sheet FORWARD of the block. Keep the tension on that sheet with your foot, hold on to something firm (not just a life line, but a stanchion or cabintop handhold, or bimini frame if it's very secure), and slide the block back. If you have to do this more than once to make sure you are holding on to the boat, so be it. You can do this twice. 

If you have two people on the boat, that second person should be on the helm. You'll be standing on the high side of the boat, and that will make it easier for you to do this.
 
"3. Reef your Sails
Combine the first two actions with sail reefing. One of the great misconceptions in sailing is that reefing is a heavy weather tactic. Nope--it's a balancing tactic. Reef earlier than you think necessary. Reduce or change out the headsail. Tuck a reef or two in to the mainsail. Reefing keeps the boat on her feet and the helm light as a feather."

 If you're going to change your headsail, please be aware of the weather before you are in it, and change the sail before it's actually needed. Changing a headsail can be extremely dangerous in high winds and/or rough water. When a boat is out of balance, the bow bounces around and moves unpredictably. If you slip up and the sail goes into the water, do you know what you have to do? You have to whip out your knife, cut the sail free and let it go, because a sail in the water at the bow can sink a boat. 

So do it while the winds are low.

Another option is to partially furl your roller furler, but understand that if you do that more than a couple of times it will permanently deform your headsail. This is not something covered by insurance, even though it's weather related. The result is that your headsail will always perform more inefficiently, and your boat will slow down some. Well, that's life -- safety first, but if you pay attention to the weather, you may avoid having to use your headsail in this way.

There's a hidden, important message in all of this: how the helm feels may be your best sign of whether it's time to twist the sails, and if that doesn't do the job, to start reefing.

What this all means is that you mustn't be shy about taking your boat out, little by little, in stronger winds than you're used to. If you're used to 10 mph winds, take her out in 15. Sail her on all points of sail. Make judgments about whether your boat needs to be reefed at this point. Some smaller boats probably should be reefed at 15 mph. 

Then take her out at 18 mph, and then 20, etc. Most people are not this methodical (and it's not typical for me, but I realized that sailing was a little more risky for me than some other people, and I just made myself do it. I am now convinced it's a good idea for all newer sailors.)

Three simple tips in that article -- simple for experienced sailors, that is. As you take your boat out for recreational cruises, pick one new skill to practice each time. Then when the ship hits the fan, you'll already know how to execute the excellent tips in that article.

Modification to How I Use My Gale Sail

Or, WHY I Keep Saying Practice is So Important


As I reported before, in my first entry about my Gale Sail, the instructions say to wrap the sheets only once around the sail before raising it.

Well, here's the rub: with my continuous-line roller furler, wrapping the sheets once isn't enough to keep it tightly furled, and if it isn't tightly furled the Gail Sale won't slide up the sail easily. Sometimes it won't slide up it at all.

The sheets also need to hang straight down, and not be secured by being led back to their cockpit-area cleats.

The solution came with the sail. The sail came with a sail tie, to tie up the folded sail and make it easier to slide it into its sail bag. You don't need it for that while the sail is deployed. It has a great advantage over line in that it's flat. I loop it through one of the sheets, counter-wrap the sail a couple of times, pulling tightly so it does not add bulk, tuck it through the sail tie and let it hang down straight.

That holds the sail tight long enough to get the sail up, which is all I need.

Several people have (quite correctly) pointed out to me that installing a second forestay close to the main one could be a great help in a storm. A small hank-on sail can be remarkably easy to deploy -- easier than a Gale Sail, certainly -- and is actually in a better position for storm sails, slightly closer to the mast.

I suddenly had an image in my mind of a boat with a Gale Sail on the roller furler AND a slightly larger storm sail on an inner stay, which with other options, such as a third reefing point, might reallly increase a skipper's options in foul weather.

I don't know if anyone has tried it, and since I'm a coastal cruiser, I would have very limited *real* need of an inner forestay. But if anyone knows of someone who has done this and actually used such a sail plan in foul weather, it would be interesting to hear about it.

We have exactly the weather I got that Gale Sail for in west central Florida right now. I would have taken the boat out in the rising conditions leading up to this if I could have, but I know I will have other opportunities before the winter is over. I'll report back how the sail performs.

My Current Storm Strategy


"Climbing (sailing) is like fun, only different."
     Tom Pattey, Scottish ice climber



When I first started sailing, I had a storm strategy. That’s good; everyone who sails should have a storm strategy.



My first plan (just avoid storms) was completely unrealistic (in two ways). That’s bad. See my three-part entry, “Out of the Bathtub!” That wasn’t even a storm – just more wind and waves than typical. We were in 5’ waves, and I was completely unprepared. I noticed on the news tonight that 8’ waves are predicted on the Gulf tonight. There’s nothing in the visible observation of local weather to suggest this. Locally, it’s cloudy with occasional light drizzle. However, to the north of us a cold front is moving south. I’m guessing now, but wondering if maybe north of here, weather is just pushing waves southward. The weather report didn’t give wave direction, and I haven’t checked yet.



It doesn’t really matter, because both weather and weather-related events, such as waves, can’t always be predicted (see my entry “Storm!”, where a significant storm seemingly came out of nowhere.)



In my first wind-and-wave event, I was woefully unprepared, particularly because of my reefing system that was so inadequate and dangerous that it couldn’t be safely used. That led to a cascade of ever-worsening events.



My second storm strategy was “just drop all the sails and motor.” That is also a significantly flawed strategy in my opinion.



First, my first sailboat had an outboard engine. In the waves we had it would have been impossible to run the engine because the engine would have kept coming out of the water, denying it cooling. On my next boat, the engine proved to be completely undependable. Now, with a dependable engine, I need to protect it. I don’t want to operate it if the boat heels more than 10º, because after 10º the oil pump cannot adequately pump oil through the engine.



The reality is that a sail plan in a really significant storm can’t and won’t be that simple, and it partly depends on your individual boat as well as your experience, and your experience with that boat.



For instance, my boat is particularly sensitive to being in balance -- that is, having the size of the headsail and the size of the mainsail matched so they work well together without allowing the boat to become overpowered (too much sail up for the conditions). I discussed this today with someone who has the same boat I do but vastly more experience, and he agrees.



For my boat, the hull shape is important. Its fat stern tapering to skinny bow makes the boat “bow tender.” In other words, the bow is particularly sensitive to wind and waves compared to some other boats.



Now, my friend already knows what I’m going to mention next. I’m still sorting it out because I haven’t been in a storm in this boat in some time and have learned a lot about how she handles since then. The first step for me would be to see where the coast is. If it’s close (I’m largely a coastal cruiser), getting away from or staying away from the coast has to be a top priority. You have to look at the chart closely and account for all possible obstacles, not just the shore itself.



The next concern will be how the hull goes through the biggest and most common waves. Unfortunately, waves don’t march like well-disciplined little sailors. While most may come from one direction, there will be contrary ones, and size will also vary. They are the concern of the helmsman. Right now, the current trend should be studied. In shallower water, the waves will be more confused and harder or impossible to predict. But you’re going to get out of shallow water as fast as you can.  :)



Once a tentative point of sail has been chosen (based on conditions, not destination – destination sailing is over for now) – it’s time to set the sails to help the boat through those waves as smoothly as possible. Wind direction has to be considered. You should have a good idea of where to put your sails, but try tweaking them for best result. “Harden them up” – that is, do things to take as much belly out as possible, such as tightening your outhaul (pulls the sail back toward the end of the boom) and the leech line (tightens the leech of the sail and helps take curve out of it). Why do that? Because a curved sail catches more wind than a flat one.



If you have a traveler, check its position. You probably won’t want to be on a close reach (often called “beating” with good reason), but you probably don’t want to be broadside to the winds either. Someplace in between will probably be best for the winds, but it may have to be a compromise between the wind and the hull, as the waves may not be from the same direction as the wind. You may want your traveler halfway between center and the end of the lee side. That gives you the option of using the traveler to quickly spill wind out of the mainsail in a gust. Simply release the upwind traveler line and let the traveler move all the way to the end. The sail will instantly become less efficient, and that’s exactly what you want.



Tweak your headsail as well. If this sail has height to it (my ATN Gale Sail is fairly short), you might want to use the position of the sheet leads to “twist” the top of the headsail. While sometimes undesirable, it is one strategy for depowering the headsail, because wind will spill ineffectively out of that twisted top.



The headsail can also be hardened up, by pulling the working sheet as tightly as possible. Many headsails have leech lines. Try to get forward to tighten that before any significant wind hits your boat.



All of this is a matter of judgment and balance. You will have your hardest time with it in your first storm, because you will have to test everything as you go, and make a number of adjustments. In subsequent storms you’ll know much more about what works on your boat. 

Is this my final storm strategy? Of course not.

Should you copy it? Don't be silly -- I haven't tried it yet. I'm absolutely certain it won't all work equally well. I have done all these things, but not all at the same time in a storm.

I'll post when I've done that. It's Florida. Inevitably, it will be tested.

Celestial Navigation

     Or, the stars may not actually hold your future

I just read online about a Great Schism in sailing. The publication Ocean Navigator reports that the Coast Guard Academy will continue to teach celestial navigation -- navigation using the stars, the moon and the sun. Amazingly, the  the U. S. Naval Academy will be moving in a completely opposite direction, They will rely totally on GPS technology. Presumably they will have redundancies built in -- more than one chart plotter, and probably more than one brand of chart plotter.

Those sticking to celestial navigation will have a little more difficult time with redundancy strategy. The obvious strategy there is to have two teams performing their calculations completely separately. However, that won't solve the problem of extended, heavy cloud cover -- for instance, in a hurricane, where it might be extremely important to know exactly where the ship is, which would identify which quadrant of the storm the ship is in. The four quadrants of a significant hurricane vary significantly in strength, so obviously, being in a weaker quadrant can be a valuable strategy.

But practically speaking, for the newer sailor, they need to know accurately where they are. We can talk about dead reckoning -- and it can work -- but only an idiot would rely solely on dead reckoning when it's a new skill. Likewise, using sextants involves using multiple charts along with taking accurate positional readings for celestial bodies, on a pitching boat. It isn't going to be terribly reliable for a newer sailor.

Celestial navigation is difficult and expensive to learn. There's no doubt it works, when you can be sure of the time and actually see celestial bodies -- but it's not fast, and there are meteorological limits.

We've talked about this chart plotter debate before, and I'm going to come back to my earlier suggestion that you use a chart plotter -- actually two. If you have a hand-held backup chart plotter and your electrical system goes out, you will still have very accurate access to your latitude and longitude.

Mark those readings on your chart at an accurate time table -- say, every half hour. Then you'll have a visual representation. You can easily compare this to your efforts at both dead reckoning and celestial navigation. 

I'm not saying that celestial navigation should go the way of the dinosaurs. Clearly, many find real value in it. I'm also not saying that chart plotters are for lazy people. But in fact, a chart plotter can you assist you as you learn both celestial navigation and dead reckoning by double-checking the conclusions you drew from the older methods. And in an emergency, let's face it -- for most people a chart plotter is going to give you information more rapidly and more simply.

Chart plotters are not the tools of the devil, and those who use celestial navigation aren't inherently superior to others. It's just a matter of interest for the great majority. So be tolerant -- "The farmer and the cowman should be friends!"

Bottom line: don't let those who know celestial navigation try to lord it over you because you don't know it yet. You're a newer sailor, and that's NOT a moral flaw. Maybe excessively harsh judgment of those coming behind one IS a serious character flaw. NO ONE PERSON represents the minimum standard to which all must line up -- especially when that status of "I'm the best and the rest of you are unworthy" is self-appointed.

Ten Minutes to Prepare

     Or, This makes a good case for practicing!

See the last article titled "Storm!" It describes a fast-growing and fast-moving storm that lasted for hours. Such a situation requires quick action to get through the weather safely and as comfortably as possible.

Suppose you only have ten minutes to prepare for a storm? Here are some things you can do, in no particular order. Some of them won't be appropriate for you and your boat. There may be things you would add to the list. The point is that you must have a plan for how to handle storms. When it's bearing down on you, that's too late to be thinking about it for the first time.

So pick and choose from what I've listed. Think creatively, put them in the right order of importance for you (you may not get through it all) and add ideas as necessary.


* Make sure you have a knife, on a tether, tied to your clothes. Everyone who has a knife should do this.

* Set your marine radio to the weather channel.

* Put EVERYONE in PFD's.

* Encourage all crew to put on gloves. Wet lines will be harder to get a good grip on.

* Offer seasickness medication to everyone and encourage them to take it.

* Secure any pets. Put them in their carriers and tie the carrier down.

* Consider whether sailing or anchoring might be your best plan. 

* Assign specific adults to see to the safety of any children aboard.

* Put one or more reefs in your mainsail.

* Furl or partially furl your roller furler, or,

* Put a smaller hank-on headsail up (check that you led your sheets correctly. You don't want them to malfunction in a storm!) Or,

* Put up your Gale Sail if you have one. Or,

* Douse your headsail and put up your staysail.

* Check your chart and chart plotter. Is there any chance of being caught on a lee shore? (Remember, wind direction can change dramatically during a significant storm.) Move the boat to deeper water before it's a battle (or impossible) to do so.

* Use the head.

* Put something to eat and drink in the cockpit.

* Make sure all hatches and portholes are securely closed.

* Close the companionway securely.

* Set up the most comfortable arrangement you can for yourself at the helm.

* Put on foul weather gear.

* Get a swim mask handy in case the rain is intense, so you can see better.

* Police the deck and make sure it's clear of obstacles. Anything left on deck will be harder to see in a storm and be a much greater tripping hazard.

* Police the cockpit. Get lines coming into the cockpit neat and ready for easy use. Clear it of anything unnecessary, but think twice before putting useful things below.

* Enter your lat and long in your log, and keep it updated. If possible, have someone mark it on the chart so you have a visual representation of how the boat is moving.

* Check the perimeter of the boat for loose lines, and start the engine. You can keep it in neutral. Turn it off if the boat is consistently heeling more than 10º because after that point the engine can't move protective oil reliably.

* Suspend "destination" sailing. Your plan now should be to get your boat and your crew through the storm as safely and comfortably as possible.


Gee, that's a lot to do in ten, or even twenty, minutes. Plan with your crew ahead of time who will do what. Issuing expected reminders are much easier for people to follow when things get tense than brand new instructions they didn't expect.

Practice ahead of time, especially things like changing sails, reefing sails, and doing things like raising Gale sails.

Storm!


      Or, You can't see over the horizon ...

Seven weeks ago last Sunday (mid-September), we had a heck of a storm here. I was up at Boca Ciega Yacht Club (BCYC) sitting on the patio, watching sailing students out on the little 16.5’ Catalinas, their first time on the water. Their instructors were teaching them to do the most basic things – notice where the wind was coming from, steering with a tiller, and tacking.

Now, BCYC is careful about the weather when we have sail school. The Catalinas are far more stable than most instructional boats because they have full-sized fin keels. However, they can’t be reefed, and are easily overpowered by what would be moderate wind on a larger boat (we send students in when we see sustained wind of 15 mph or more, and actively encourage members to not take the boats out on windy days as well).

But this was a beautiful mid-September afternoon, and “storm season” (not hurricane season) was just about over. Except … September was exceptionally warm this year, more like August.

The prediction for that Sunday was a 30% chance of rain. There was no prediction for particularly bad weather. But it’s Florida, and when it’s 90º on the coast, it is often 95º inland. Very often we get a sea breeze that forms in the afternoon from the west, which hits the stronger prevailing east wind coming off the Atlantic and across that hot interior. Thunderstorms can be the result. Two walls of wind colliding with lots of heat and humidity often means thunderstorms. However, they typically form at least a little inland from the coast, especially by September.

This day was going to be different.

There were probably 15 people on the patio. The “Waterfront Director” is the person who makes the final decision about whether or not students should be called in due to weather, but none of us saw any signs of trouble … except for one man. Unfortunately I didn’t have my camera with me that day, but we had a similar weather pattern the next day, so I took my camera up to BCYC the next day like a storm chaser, hoping to get lucky – and I did.

This first picture is very like what we saw that Sunday, a little before 4PM: clouds, but relatively formless, and not threatening-looking at all. They kind of looked like cotton candy.


Innocent-looking "cotton candy" clouds. Only one person realized they
were actually "blow off" from a huge storm just out of sight over the horizon.
Only one person on the patio looked at the clouds suspiciously. He went to the club’s computer and checked the weather radar. The radar (which you can get on your cell phone if you’re close to the coast) showed a massive gathering of angry-looking red and orange. I couldn't take a picture of the radar on Sunday, but I saw it, and it was huge, moving west and bearing down on both Pinellas and Manatee County – and just over the horizon -- out of view on land. The clouds we could see from the patio were pretty. The radar, however, was scary.
He and the Waterfront Director talked, and they quickly called the student boats in. We got all the students in ten minutes before a wall of wind of at least 40 mph hit us. We would have had five student boats out in a terrible storm if one person hadn’t realized that those sweet fluffy clouds we were looking at weren’t sweet at all – they were an alarm warning.

Here are photographs I took of the next day's storm. First I’ll show you what was happening on the radar. Each picture was taken less than five minutes apart, so on Monday, as on the previous Sunday, we had a rapidly building storm. It didn’t cover as much geography as the one the day before had – but it could have.




Rapidly after seeing the first innocent-looking “cotton candy” clouds, we saw something like this:


Still not terribly threatening looking, but it rapidly (and I mean, within minutes) developed into something like this (actually, all of these pictures would have been more ominous on Sunday):



And then this:


See how the “cotton candy” clouds are still there in the background? But they’re higher now. You don’t have to be a meteorologist to see that you’re looking at turbulent air. Turbulent air and sailboats? Not the best combination!

The storm was rapidly building. Within two minutes, the sky looked like this:


Those are clouds to pay attention, to, aren’t they? They’re well organized, and growing both vertically and horizontally. At this point, you would be checking weather radar if you had it available to you. Here’s what you need to know about weather radar: the images you see may be 15 minutes old, and when faced with a rapidly growing and intensifying storm, data that is 15 minutes old may be misleading. It may not yet be showing you that rapid intensification. Your eyes and your senses may be much more valuable at this time. By now, you should be preparing for a possible storm, because that storm may move toward you, and even if it doesn't do that directly, it may expand to the point that it envelops you.

Actually, we should have been on high alert from the first glimpse of the “cotton candy” clouds. Why? Because they represented a CHANGE in the weather. Along with an unexpected change in wind direction, temperature or force, an unexpected change in the clouds should get – and keep – your attention.

Within a few minutes the storm was nearly on top of us, and the sky looked more like this. Monday, however, BCYC was on the edge of the storm. Sunday we were in the thick of it, and there were no patches of blue sky showing. The wind was starting to pick up significantly.


From the radar on Monday, it was clear that the bulk of the storm today was going to hit south, in Manatee County, so I went south and crossed the Skyway Bridge. Approaching the Skyway Bridge, this is what I saw:


The wind was gusty, although not as bad as it had been the day before. This storm was smaller and not as bad as the one on Sunday, but you wouldn’t want to be out unprepared in this one, either.

Something should jump out at you at this point: there are no waves. You must be thinking, “What is she talking about? That’s just rain. You’ll get wet, but it’s not a crisis.” You’ve probably seen descriptions of how to judge the strength of the wind by looking at the surface of the water. For instance, at around 12 mph, white caps start to form. By the time the wind is up to 15ph, you’ll see a lot of whitecaps.

Except.

It takes a while for the waves to form. When a storm is rapidly forming, the wave development will lag behind the wind. This storm, as well as the one the day before, grew rapidly, and the wind on Monday, which I estimated to have 30 – 35 mph winds, was plenty strong enough to concern any newer sailor, even though it wasn't as bad as the day before. Monday's storm also didn't last nearly as long as Sunday's did.

Another thing you may have been told is that these storms pop up in Florida but don’t stick around very long. That can be true (see my story, “Oh Dorothy!” for an example of strong but short-lived storms).

However, the Sunday storm was different. It kept growing, and reforming, and re-strengthening, and here’s an example. Two members of BCYC, well-experienced sailors, and another couple who were just along for the ride, were about four miles out on the Gulf of Mexico when the Sunday storm hit the coast. They were trying to return to Gulfport, but their boat’s engine could make no headway against the storm, and they had their hands full managing the boat. Their friends could not be much help.

At 11PM they were still caught in the storm. They were exhausted, and wet, and hungry, and they threw in the towel and called for a tow. The towboat was able to fight the waves and the wind and get them safely home. It is not typical for afternoon storms to last that long – or, for that matter, to develop with so little warning. But it does happen.

So what are you to do?

What you should NOT do is print out this article and look for these kinds of clouds. You won’t always see “cotton candy” clouds before a storm. What you should watch for is changes in the weather that might be an early warning system. In addition, you should tune your radio to the weather channel. A weather advisory was put out very early for the Sunday storm, and there’s a lot you can do to prepare for a storm, even when you only have a few minutes. See the accompanying article, “Ten Minutes to Act,” for things you might get done if you have ten minutes warning before a storm hits.

Gale Sails!


      Or, The Inventor is One Clever Dude!

One important strategy if you get caught in a storm is to have less sail up. It makes sense – if the wind is pushing and pulling your boat harder, it will take less sail area to move the boat when the wind is strong. If you have too much sail up for the weather conditions, we say that your boat is “over-powered.” The boat will heel too much, travel sideways as well as forward, and, if the situation becomes serious, become significantly unstable. It could even tip over a full 90 degrees (called a "knockdown"), possibly damaging the rig and with the real risk of injury to you and your crew. The bow can swing around wildly with the boat rocking forward and backward as well as side to side, an unpleasant ride. It’s important to reduce the amount of sail you have up if you’re in a significant storm – and to me, “significant” means any storm where your standard sail plan overpowers your boat.

In addition to reducing sail surface, reducing the size of both sails helps to keep the boat in balance. When the boat is in balance, the amount of sail up matches the weather conditions, and the headsail and mainsail are working well together. Neither one is too big. A boat that is in balance will respond more reliably to the helm and give the people on the boat a more comfortable ride. You might not think that is important, but some storms last a long time (we had a big storm here about seven weeks ago that lasted for hours), and seasickness is more than nausea – it can make you dizzy and even disoriented. It can seriously incapacitate you or valued crew members. I know a skipper who actually tied a crew member to the mast for her own safety once when she became so seasick, and so disoriented, that the rest of the crew was afraid she might not be able to keep herself on the boat.

On most boats, it should be easy to reduce the size of your mainsail with a good reefing system. The headsail, however, can be more problematical. If you have a hank-on sail, it means going forward, taking the old sail off, and raising the new sail. That’s going to be tricky if you’re by yourself, and best done before the wind picks up (which may happen before the full storm hits you.)

If you have a roller furler, you have different choices. It can be tricky to change sails. You can usually partially furl your headsail, but if you do that often, it is likely to deform your headsail in a significant way, stretching it out and making a pouch in it where there should not be one. Sail fabric near the clew is very stretchy because it’s on the bias, and it will stretch out, especially in a strong wind.

On my boat (and many other boats of that era), it’s more complicated. My roller furler cannot be partially furled. Even if I wanted to take that step, I could not. No matter how you secure the lines, it will fully deploy, a bad thing to have happen in a storm.

But in addition, on boats where the headsail can be partially furled, one has to use the furling line to keep it partially deployed, and that line takes a lot of strain in a storm. Unfortunately, one has to use small-diameter line for the furling line because it all has to fit on the drum. It’s not as strong as thicker line. Sometimes that line breaks, and then you will have an uncontrolled headsail in a storm, not a good situation.

My solution is the ATN Gale Sail. To use a Gale Sail, you completely furl your roller furler, wrapping it only once and letting the sheets hang straight down. The Gale Sail has a leading edge that wraps around the roller furler and is secured with stout barrel clasps. A pendant attaches it at the bottom (I use stainless steel hardware through a hole already drilled into the anchor roller). Five barrel clasps (on my sail) wrap the orange leading edge securely around the roller furler. A spare halyard or spinnaker halyard is used at the top.

 The ATN Gale sail, with its trademark orange
wrap-around luff, deployed

I tested mine last week when we were having a lot of wind. I had an injured back, so although my main was reefed, I did not raise it. While waiting for a bridge to open I was in a wide, deep space, and I sailed the boat around using just the 60 sq ft Gale Sail, the size recommended for my boat.

I was impressed with two things. First of all, it was remarkably easy to handle the sail in the 25 mph winds I was experiencing. My 135% headsail by comparison is a real handful under those conditions and takes considerable strength to manage, even with self-tailing winches and a good winch handle.

More impressively, that very small sail moved my boat at up to 4 knots. What this means is that the sail can pull its weight and really help keep the boat balanced in higher winds.

The Gale Sail does have one drawback: it isn’t a piece of cake to put up (the advertising suggests otherwise). You had better pay attention to the weather and give yourself time to get it deployed, and practice using it before you need to. The more wind a sail is designed to take, the heavier the fabric used is, and the Gale Sail fabric is stout and extremely stiff. It’s tricky to learn how to maneuver the barrel bolts and it won’t go up quickly the first time you use it.

I suggest you use snatch blocks if you can to guide your sheets back to the cockpit. If your boat has rear blocks, as mine does, make sure the sheets you put on your Gale Sail are long enough to use them, because that rear block assures that whatever line you’re using will come to the winch at the proper angle, helping to avoid winch wraps. A winch wrap would be a dangerous complication in a significant storm, another reason to practice how you’re going to handle this sail.

My Gale Sail folds easily and easily fits in its storage bag.

I go a little for the overkill when it comes to safety, and I will keep the Gale Sail on deck, lashed to the starboard lifelines (I keep all obstacles, including spare rope, fenders, etc., on the starboard side, and then know I can always go up the port side unimpeded.) I don’t want to have to use precious time going below and digging it out from under a settee.

I am going to practice with it more and will post an update about how fast I can reasonably expect to get the sail up by myself. Even sailing with someone else, that person would be on the helm while I was putting this sail up. Unless three people are on the boat, I could not be certain I would have help with it.

I am not unequivocally recommending the Gale Sail over other solutions. Most people won’t practice putting it up and might not have enough time to get it up, especially if they haven’t been paying attention to the weather (and unfortunately, many people do not).

A quicker solution is to use a staysail on a second forestay between the mast and the bow, but this is also complicated. That second forestay has to be installed properly, and the added stresses on the mast have to be accounted for. You can’t just put another stay on your boat, then put a sail on it in storm conditions, and not look at the effect on your overall rigging.

However, if you choose this option, you can then have a hank-on sail already latched on to the stay and held over to the side with a bungee (it would be the starboard side on my boat to keep the port side clear) if you anticipate possible bad weather. In a sudden storm, you can get a hank-on sail up faster than you can get a Gale Sail over your roller furler. There’s absolutely no doubt about it.

A staysail has another advantage because its position, slightly closer to the mast, can be a more effective spot for a storm sail than one deployed from your forestay or attached to your roller furler. However, that advantage may be a small one, important if you are a racer but less significant if your goal is simply to get through a storm as comfortably and safely as possible.

If you don’t have a roller furler, the Gale Sail is not suitable for you. But you can have a smaller headsail secured and ready by your forestay. You may even have room enough on the forestay to have that smaller headsail at least partially hanked on before you leave the dock. That depends on the cut of the headsail you use most of the time.

Before making a choice, educate yourself fully regarding how you want to modify your sails in a storm. Don’t just take someone’s word that you “have” to have a staysail, or that hank on headsails are “best,” or that the ATN Gale Sail is the right answer for everyone.

The important thing is to have a storm plan. If it’s warm enough for most people to be sailing, there will often be at least a small chance of a storm. See my soon-to-be-finished entry titled “Storm!” Only a 30% chance of storms was forecasted for that day. It wasn’t typically a time of year where we experience strong storms here. But we experienced a very significant storm that lasted for hours with very little warning. Storms happen, so have a well-thought-out plan.

Do You Want Your Keel Under the Boat or IN the Boat?



     Or, the coast is not always your friend!

In rough water, or in rough weather, you need to move away from the shore. I’m not kidding. This is serious stuff.

I know. It’s counter-intuitive. Most newer sailors want to stay close to shore, and especially in a storm, which is scarier than sailing in calm weather. A lot of newer sailors worry about falling out of the cockpit when the boat heels, and shallow water feels safer. How many times did your mother tell you not to go into the deep end of the swimming pool when you were little?

But you’re not in a swimming pool. You’re on a sailboat. You’re not going to fall out of the cockpit (even in a bad storm there are very good ways to keep that from happening, honest!) And, in your swimming pool, if a storm develops, you just get out of the pool and go inside. It isn’t quite that simple on a sailboat in a storm.

Storms are not static, and they’re not completely predictable. They can pop up on what seemed like a perfect day to sail. They can move or remain stationary. They can expand, contract, and even rotate. They can join other storms. They can develop right over you. The point of this is that you can’t necessarily predict where the wind will come from (unless you are a very unusual beginning sailor with lots of weather forecasting experience), and the fact is that the wind direction can shift on you during that storm.

Why does that matter? It matters because you need to keep your boat in deep water during a storm. You don’t want to be caught near what is called a “lee shore.” That doesn’t mean the storm is on the other side of the island. It means the wind is blowing you toward the shore. The wind is to the windward side, and the shore is to the leeward side, of your boat. The wind is pushing your boat toward shore. Even if you don’t have a lee shore right now, the waves may be pushing you toward the shore, because it takes a while for the water to change direction after a wind change. In other words, the wind may be pushing you in one direction while the waves push you in another (and in shallow water, that situation is a real mess!) Either way, it’s not an ideal situation. And, you can’t assume that the wind direction you have now will remain where it is. A wind shift could suddenly put you next to a lee shore, and you might have a hard time getting out to deeper water. Better to move there sooner rather than later.ß

So then, think about scary things you’ve seen about boats: they can break, and then they sink – or have you not seen the movie “Titanic?” Water doesn’t break boats -- "Poseidon" is a fiction movie. Boats hitting hard things break boats.

Don’t break the boat. You avoid that by staying away from hard things that can break it, like icebergs … and the ocean’s bottom. In deep water, the ocean (or lake) bottom is farther away from your keel. That’s what you want.

Where I live, the danger near the shore is generally shallow water. (It’s even worse in some other places, where the shallow water includes hidden, big, sharp rocks.) When the water gets rough, a number of things happen in shallow water.

·      The waves tend to break. That makes rough water even rougher.

·      The waves tend to come closer together. That makes the water not only rougher, but harder to manage as well. The water can even get very confused, much like a giant, front-loading washing machine. Do you really want to try to pilot your boat through a giant, front-loading washing machine? No, I didn’t think so. The waves will be easier to handle, and you and your crew will be much more comfortable, away from shore.

·      The waves tend to push you toward ever more shallow water. If you have any other problems – and you may well have other problems by this point, because things often go wrong in clusters (see my personal experience story, “Out of the Bathtub!”) – it will be much harder now to move your boat back out to deeper water.

·      Now you’re really in trouble, because the waves have been bouncing your boat up and down, and other things have gone wrong, and now it’s all happening in shallow water. I know someone this happened to, and the breaking waves banged his boat against the bottom in the shallow water, and  drove the keel right through the bottom of his boat. His boat sank in four feet of water. No one was hurt, but the boat was totaled.

·      Many boats have unprotected rudders, and in these circumstances, your rudder may end up broken, and then you won’t be able to steer. Three guesses how I know …

So what do you do? Turn your boat away from the shore – and before all these things start to happen (using at least a 45º angle through the waves – experiment in calmer water to see how she goes through best, and you'll probably find that 45º isn't enough). If you’re scared, tell everyone to put on PFDs (if you’re scared, you should be more scared in shallow water). Employ all your other safety devices – tethers, drag line, etc. It’s very unlikely that you’ll need any of it, but you’ll feel better, and feel more in control. What you don't want is for the waves to hit the side of your boat. That will be the roughest, and the scariest, way to ride it out. If you have to make a big turn, do it between waves so you don't get caught with the waves "abeam," or hitting the side of the boat.

If there is someone on your boat who is highly experienced, don’t be ashamed to turn the helm over to him or her.


LESSON LEARNED: There’s a lot more you need to know about sailing your boat in rough water, even as a newer sailer, and you really do need to know it. Buy yourself a copy of Sailing For Dummies, and do it today. Then read it very carefully. It is an outstanding book for newer sailors, and as you’ll see in my story about the time this happened to me, it really helped me. I did turn the boat out to sea, over the protests of the equally inexperienced person with me, and it’s a good thing, because we did have a cluster of failures. But we didn’t get thrown into the water, no one got hurt, and we didn’t break the boat. That’s a good outcome.

Rough water doesn’t have to be a crisis. If you think there’s any chance of rough water, and any chance that you will get seasick, take something like Bonine in a timely way. Encourage your crew to do so as well. One or more people on the boat incapacitated by sea sickness is one of those things that can contribute to a “cluster of things that go wrong.” If you get caught in a difficult situation, you need everyone able to help out. It sounds trivial, but seasickness can completely incapacitate a person -- and even turn into a true medical emergency from dehydration.

Should you just try to get to safe harbor? Well, I’m assuming you paid enough attention to the weather that you know this is only a thunderstorm, and not a hurricane you thought you could just dodge. But thunderstorms can move at up to 60mph, and I’m pretty sure your sailboat can't go that fast. If you try to get into a safe harbor, there’s a very good chance that you will only succeed in putting yourself close to shore, or even worse, in a channel in very rough water. If your boat has an outboard motor, it’s an even worse choice, because an outboard won’t be any help in confused waters, and in fact you could ruin it as it keeps bobbing out of the water with no access to cooling. 

However, that's all a judgment call. If the storm is just forming and is currently far away, that's the time to head for safe harbor (which could just be a little cove sheltered from the likely direction of the wind). If you do that, put an anchor out -- two, if you have them (and you should have two). The storm might be parallel to you at the moment. I say don't do it, but friends did it in Biscayne Bay when I was on their boat. We headed in the moment the skipper saw signs of a storm forming -- he saw gathering haze and didn't gamble. We got in just before a really big storm hit. 

Riding out a storm may not be fun. You may get wet – but it’s just water. You may get seasick, but you won’t be sick forever. The ride may be rough, but the storm will end. You don’t want to be caught in a pounding surf with a keel under you and crashing waves abeam, with no way to turn the boat. Get your boat into deeper water in a timely way.



ß This is where you have to have that “I’m the skipper” attitude, because you cannot allow debates over whether or not to move the boat away.  Moving the boat away from shore may upset or scare someone on your boat. But it is your boat, and your insurance, and you are responsible for the boat and passengers’ safety – not the scared person who doesn’t know about lee shores in a storm yet. STICK TO YOUR GUNS and don’t allow a debate. YOU are skipper; YOU make the crucial decisions for your boat unless you are CERTAIN the other person knows more than you. Even then, I would still move the boat away from shore. It won’t hurt anything to do that.
