Latitude 38 has an article about a British sailor who fell overboard while crossing the Pacific from Japan. The report says that he was conscious and wearing a life jacket when he went overboard. His fiancee was on-board but unable to rescue him.
I am a strong believer that you don’t want to get separated from your boat. Staying on-board is the obvious first solution but there are situations when the elements just conspire against you and you get swept overboard. Then having a good tether attached to the vessel and your safety harness is your best bet. We offer a number of harnesses and tethers which meet most needs. A double acting snap hook is your best bet, the less expensive carabiners can get disconnected when twisted in just the right manner.
