Don't Fall In!
I agree with Daniel - rule number one is don't fall in. I wear my tether at all times when single handed or with someone who can't sail or pull me aboard. It is important to make sure that your jacklines are taught enough that they won't let you slide under the lifelines, but not bar tight or they may break the fittings to which they are attached. Life line netting can also help, though you should make sure the nettting you use is solid enough to catch you. If you lace it correctly, a load in the netting will be distributed across several stantions and the pulpits. Once you are in, it is really hard to reboard. I had a customer last year who pulled himself out of 50 degree water with his gennoa sheets at the youthfull age of 75. I tried it later in the summer and had a hard time at 25! That's with the boat sitting still. Try it with the drag created by moving through the water and it becomes almost impossible. I don't know of anyway to make it easy.You can, at least, make sure the boat doesn't sail away by holding your sheets while sailing alone instead of cleating them, but if you probably weren't in the cockpit if you are now swimming.While we're on it - I have also replaced the connection between my mainsheet and the travler with a snap-shackle. Now if someone goes over board and there is another on board, its easier to drag them back up using the leverage the blocks provide.Justin - O'day Onwers' Web
