150 units have been built.
The Commander 31 bianca is a heavy sailboat which is under powered. It is very stable / stiff and has an excellent righting capability if capsized. It is best suited as a coastal cruiser.
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.
