Interestingly enough, at 22 lbs of floatation, that Stearns offshore life vest doesn't qualify in the ISAF Offshore Special Regulations (you need 33lbs of floatation). Not only you need floatation, but you also need one with an intergral harness and now you need it equiped with a crotch or thigh straps! I have had two accidental inflations while racing so I now switch mine to manual. I think you will run a much greater risk of falling overboard in one of the "normal" ways rather than having rigging, explosions, fire, gunfire, etc. ripping your vest. But most important - If you are wearing it, it is survival gear, if it is down in the cabin it is merely cargo.
