The Mariner 31 is a 30.67ft masthead ketch designed by C. Oberly and built in fiberglass by Far East Yachts (JAP) since 1968.
The Mariner 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 small. There is a short water supply range.
