Classic 31 Grampian
8 / 34 - score 58%
The Classic 31 Grampian is a 30.91ft cutter designed by Peter Van Dine and built in fiberglass by Grampian Marine since 1964.
The Classic 31 Grampian is a heavy sailboat which is slightly under powered. It is not stiff and has an excellent righting capability if capsized. It is best suited as a bluewater cruising 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.
