12 / 106 - score 70%
The Mamba 311 is a 30.68ft masthead sloop designed by Bengt Karlsson and built in fiberglass by Mamba Boats (SWE) between 1983 and 1986.
The Mamba 311 is a light sailboat which is slightly under powered. It is very stable / stiff and has a low righting capability if capsized. It is best suited as a day-boat. The fuel capacity is originally very small. There is a short water supply range.
This boat has a reasonable score and ranks in the top quarter. It is a good choice.
