Your Autopilot Could Throw you in the Drink -- Really!

I'm a big fan of autopilots. Some people call them their "invisible crew member" or some other crew nickname that shows just how valuable they can be. If you're single-handing, for instance, the autopilot can keep your bow pointed into the wind while you raise the sails. No one ever told me what I'm going to tell you now, though. I heard "You should have an autopilot" over and over, but not one person said, "However, it can throw you in the water" -- until I said it. Then others agreed with me. I think it's just a good rule of thumb that anything you put on your boat will bring risks as well as benefits.

There's a saying about sailing that the number of errors equals the number of crew members -- squared. This includes your autopilot, because they can malfunction, and they can do so unpredictably and at just the wrong time -- just like humans.

An untended autopilot caused another boat to hit mine once. My helmsman had turned the helm over and was on my cabintop photographing the boat that ended up hitting me at the time, so we know exactly what happened. The "skipper" of the other boat 1) had his boat on autopilot, and 2) wasn't at the helm. The photos very clearly show him sitting on a side bench next to his cabin top, nowhere near the helm.

Sorry, but autopilots aren't really crew members, and a human has to be at the helm at all times. If common sense didn't tell you that, maritime law does.

Why is this important? His boat was sailing very fast, at least seven knots. He was only about ten feet away from us, silly really since we weren't racing and there was plenty of room.

So when his autopilot suddenly hiccuped and turned his boat 90º to port, at his speed even if he had known what was going on, he wouldn't have had time to steer away. His boat went right across the stern of my boat, leaving his bottom paint behind. His anchor hit my split back stay. It probably would have pulled the whole rig down except that the stay had a plastic PVC cover on it. The anchor, thankfully, rolled off the stay, damaging only the cover.

Autopilots can do that. They can be steering the boat dependably for quite some time. Then a wave hits the rudder wrong, or the power hiccups, or -- you won't always know why, but the boat suddenly makes a hard, lurching, and completely unpredictable turn.

If this happens to your boat and you're on deck somewhere instead of in the cockpit, and you're moving at 6 - 7 knots, that sudden turn can throw you into the water.

So what do you do? Because we all know we're not going to give up our autopilots.

First of all, any time you're relying on autopilot while you move around the boat, slow the boat down to the minimum speed you need to maintain steerage. That's whether you're going on deck or below decks, because you don't want to be thrown around in the cabin either. I suggest that you slow down  even if you have someone at the helm, because humans can control for things like errant waves in ways that electronic gadgets cannot. It's all about keeping the person who is out of the cockpit safe.

Second of all, always remember the old rule, "One hand for the boat, and one for yourself." Don't be up on deck doing something with both hands, and nothing to hold on to. If you have to use both hands, then you should be tethered. For instance, if you're reefing the boat, clip the tether to your PFD, wrap it twice around the mast if it's long, and then clip it to your PFD again. I know someone who did that as a storm approached. The wind hit before he was done reefing, and his boat heeled over nearly 90º. He was knocked off the cabintop but stayed on the boat, which saved his life.

Autopilots are terrific. They let you go down to the head, or grab a sandwich, or get that CD you want. Used intelligently in open waters (not near other boats, for instance -- please, I don't want to be hit again, and you really don't want to hit another boat), they are a tremendous asset. Just remember that they introduce a new element of risk along with all that tremendous convenience.

Beyond this, ALWAYS ask yourself when you get a new piece of equipment: "OK, I know the good it can do -- what can it do that's bad?" A preventer can keep you from a dangerous jybe when you're sailing downwind. I don't know how many times I've heard that. However, only one person ever pointed out that if you attach it to the boom in the wrong place, it can bend (destroy) your boom.

We're all newer sailors here, but I know for a fact that people who have been sailing for more than 60 years are still learning things. Complicating this process is the fact that we don't know what we don't know. So we don't know that the autopilot can send us for a swim, or that the preventer can bend the boom. Take all the things you have on the boat and make sure you know the downsides as well as the upsides. The internet can be a great help, but use it with caution, as the internet is packed with misinformation, some of it dangerous. As you keep poking around, you'll start to get a sense for what is and isn't likely to be true.

This one is true: your autopilot can pitch you in the drink. Turn it off if you have crew and put someone on the helm before you leave the cockpit. If you're by yourself, slow it down to steerage speed.

And have fun out there!
