Hb 31

8 / 37 - score 57%

The Hb 31 is a 30.5ft fractional sloop designed by Van de Stadt and built in fiberglass by Hunter Boats Ltd. (UK) between 1983 and 1985.

25 units have been built.

The Hb 31 is a light sailboat which is a good performer. It is very stable / stiff and has a low righting capability if capsized. It is best suited as a day-boat.

This boat has an average score but ranks in the top quarter. It seems difficult to do much better. It is one of the best possible tradeoff for this request.
