Hullmaster 31
5 / 73 - score 77%
The Hullmaster 31 is a 31.25ft masthead sloop designed by Edward S. Brewer and built in fiberglass between 1973 and 1979.
The Hullmaster 31 is a heavy sailboat which is slightly under powered. It is very stable / stiff and has an excellent righting capability if capsized. It is best suited as a bluewater cruising boat. The fuel capacity is originally very small. There is a very short water supply range.
This boat has a good score and ranks in the top quarter. It is an excellent choice.
