Best jackets today made by Spinlock (UK) but not cheap and you would need to convert to manual inflation. They can be fitted with a spray hood.

I've lost two friends to drownings in what were normal weather conditions in what should have been perfectly survivable situations. In both cases the man overboard was observed, rescue started immediately and help arrived within five minutes, which proved too late. RIP Tosser and Maxie (ex TAA).
