Liferaft
Have not had to use a liferaft so far, but am impressed by Switlik's information and apparent attention to details. There is some question about getting a small (undersized) one so as to keep people huddled together & keep them warm. Too large a one, and people get tossed around inside them in rough weather. ( And when are you most likely to be using it?) Units I've priced are around $2000. new. There may be some available used , on ebay or through manufacturers for less. BoatUS also rents them to members if you want one for a particlular passage or period.
