I always keep mine on-board, but never really thought about guests. I think that is an excellent point in cooler water, right up there with the raft, at least.wetsuits are not a bad ideal for cold water sailers. Survival suits are better. But we scuba dive and already have wetsuits. Even in a life raft hypothermia could be deadly.
Sure! But, can you imagine spending 72 days in the open sea in that!Does this count.
