Tether
Maybe it's just anal, but I have this fear of being tethered to the boat, and being drug through the water while it sails/motors merrily along. Luckily I am pretty sure footed, and have never been close to going over the side. But, when it gets really snotty out there, I clip myself to a cleat on both sides of the cockpit. I can not get out from behind the helm, and can't move around much, but I can't go over the side. A 6' tether on a jackline down the side of the boat will let you get into the water if you fall. Those of you who think you can get back into the boat, with no help, while it is making five or six knots, need to give it a try. Then tell me you can do it. The need to go forward is dealt with as it happens, and I do not have any certain procedure, except hang on tight.
