Practice in good conditions
keeping in mind that it will probably not be like that when it happens by accident. Dress in your cold weather attire - wool sweater, fleece pants, rain gear, etc. It is amazing how much weight that stuff adds when it gets wet.My wife went overboard while we were docking early one morning at Port Townsend. She fell between the boat and the dock while stepping onto the slippery dock. She caught the lifeline under her arm as she fell and dislocated her shoulder. We were wearing the automatic Crewsavers and hers unquestionably saved her life.The location where we were docking was in an area where there are serious wakes from ferry boats, wind, and strong tidal currents which would slam the boat into the dock with considerable force. The stern line was temporarily secured when I got onto the dock, but I did not think that she was protected from crushing enough by the fenders and so I was afraid to leave her while I secured the bow line. I pushed the boat away with one hand and tried to lift her the two or three feet over the dock railing with the other. What I soon discovered was that there was no way to get a good enough hold of anything that she was wearing to lift her. She was cold, wet and her clothing was very slippery. The lifting strap attached to the vest had been packed such that it was under the bladder of the vest and it was not apparent to me that it was even there. The built in harness was not accessible either when the vest inflated. I could not get a good grip on anything she was wearing. No help, no belt, no harness, no lifting strap, no tether, no hood on her rain jacket and I could not use a pants pocket either because it pushed her under water when I tried it. I was eying her hair but she was panicked and would not let go of the dock line with her good arm except to protect her hair. I finally got her to raise her legs enough to get ahold of a pant cuff. I lifted her leg up enough for her to hook it over the dock rail while I rolled her up onto the dock upside down. It took a remarkably long time to get her out of the water - probably ten minutes or so and I was beginning to weaken from the cold almost as much as she was.Then I was again surprised because I could not figure out how to deflate the vest and get her into some warm clothes. I finally figured that out and she took a slightly warm shower to warm up. Then we went looking for a doctor to get her shoulder fixed up.So to sum it up, check your gear regularly, read the directions, practice, wear all of your gear and try to imagine varied scenarios that you might not normally expect. Keep in mind that people have been killed while practicing, too.I wear a Stearns manual inflatable jacket almost all of the time (even at the dock) and usually wear an automatic vest with harness while underway. I have a short tether always attached to the harness too. When flying in small aircraft, I have a Stearns manual inflatable "bush pilot" nomex vest which has a lot of pockets for flares, radio, cell phone, flash light, strobe, etc. email me if you want a good source for this stuff or look online at eBay, etc. e0550@comcast.netDragging a line to save yourself is NOT going to work if the boat continues at a speed of more than a knot or so. I have tried it and at 1.5 knots, I can barely hold onto the line much less pull myself to the boat. At 2+ knots, the water pulls you completely under the water and EVEN IF YOU ARE WEARING A VEST, YOU WILL DROWN. DO NOT EVER TOW SOMEONE IN A LIFESLING. Read the directions!
