Too Much Sail Up!

I heard about a sailor the other day who, as they say, ended "up to his neck in alligators." I'll call him "Dick."

Dick had taken a several-day sailing trip with a couple of friends who had sailed some with him before but who didn't have a lot of experience yet.

Dick was the person at the helm. they were sailing with an asymmetrical spinnaker out. An asymmetrical spinnaker flies to either the port or starboard side of the boat, not out in front while running downwind, as a symmetrical spinnaker is used.

As you can see, that's a lot of sail. Now, there are some basic rules about sails.
  • The heavier the weather for which the sail is designed, the heavier and stiffer the fabric will be. My ATN Gale Sail is only tricky to attach to the roller furler because the fabric is so stiff. But because it is stiff, I can make that sail completely flat, something you want in higher winds. 
  • The higher the wind, the smaller you want your sails to be. This is why mainsails can be reefed. 
  • The higher the wind, the stronger you want that sail fabric to be, so it can take the extra wind pressure without ripping.
  • The higher the wind, the flatter you want the sail to be. A big belly in a sail catches a lot more wind than a hard, flat sail. Look at the belly in that picture above -- wowsa!
A spinnaker sail fails on all four points. Spinnaker cloth is just about the lightest-weight sail cloth made. When the winds pick up significantly, at some point it's time to take the spinnaker down, or "douse" it.

Well, Dick didn't pay full attention to what we call "rising conditions." Both the winds and the waves were picking up. All of a sudden his boat took off, racing on the overpowered spinnaker. The boat was out of control.

So now he had some decisions to make -- who does what? (Remember my article "Ten Minutes to Prepare?") Part of deciding who will do what is making sure that the person will know how to execute his or her designated task. Unfortunately, Dick is an optimist and did not anticipate this change in conditions. He also didn't assign tasks ahead of time, and he didn't train those people for their assignments.

But I know what the BIG thing is that went wrong for Dick -- he's a helm hog. He doesn't want to share the helm. Because of that, he did not have a skilled backup helmsman.

When he found himself overpowered, he had to go up to the bow in rough seas and douse that great big sail, keeping it under control and out of the water (having that sail go into the water would have been extremely dangerous. It could have pulled the boat over and then under like a submarine.) He had two relatively inexperienced people back in the cockpit, one of them on the helm. The person on the helm couldn't hold a steady course with the increased wind and waves, and who could blame him? You need to have someone else who can take the helm, but you have to teach that person and give him or her time to practice. Otherwise your backup helmsman is going to have a hard time. You have to share the helm if you're going to have an adequate backup helmsman in a pinch.

Dick called out instructions, but the new helmsman either didn't understand the instructions or couldn't execute them. It could have been a combination of both. In any case, they ended up with a line in the water AND wrapped around the rudder. When the people in the cockpit realized they couldn't steer, they started the engine. That is only a good choice if the helmsman and crew are certain that there are ... no lines in the water. The line then very efficiently wrapped itself around the propeller as well.

Again, this is a problem resulting from poor crew training and lack of time doing important things on the boat, what a friend of mine calls "time over water" (and not just as a passenger). There are extremely directive skippers out there, who give so many detailed instructions that the crewmember is just an extension of the skipper, doing no thinking for himself (picking a sex). The more prompts you give as a skipper, the less your crew member will actually learn.

Your crew has to practice these things under calm conditions, and "checking for lines in the water" needs to be drilled into everyone's head before they go *anywhere* near that engine -- in fact, all the time. That line wrapped itself around the rudder without any help from the engine. If you're going to take beginners out on your boat, you have a responsibility to teach them those basic things. If something happens, starting the engine is a very reasonable thing to do. They need to know how to do it safely.

He had to cut the spinnaker lines and let it drift away, but all's well that ends well. The skipper also had to go over the side to untangle that line from the rudder and propeller. That's not so good; he had to leave his boat for the water with crew on board who were already struggling. Again, all's well that ends well.

BUT:

You can avoid a lot of this by discouraging a casual attitude toward sailing on your boat. Make sure that your crew knows that it can be a little dangerous. Make sure they truly know how to perform the tasks you're going to assign them. Teach them patiently and give them a chance to practice.

I was on the sail school's safety boat one day when the students were learning to dock (those of us on the safety boat call that "target practice.") Each student boat made pass after pass, and we could hear the instructors giving tips and encouragement to their students. If the students were doing the docking, they should have been giving the directions to the teacher and other student, but each time, it was the teacher speaking.

Then one of the boats approached. I looked at the instructor, and she had her hands over her mouth! One student was in charge of the docking with the other student crewing. The student did a great job. Then they made another pass, and the other student executed the "mock dock." He did a great job too, and the teacher still had her hands over her mouth.

Hats off to her. She knows that unless those students can dock the boat without any prompting from her, they can't dock the boat. That's what you should do, too. If you want your crew to be able to tack the boat without your help, put one of them on the helm and one of them on the sheets -- and then zip your lips.

And for heaven's sake, don't be a helm hog. One day it could be your life on the line.
