The Seaman 30 is a 30.42ft fractional sloop designed by William H. Tripp Jr. and built in wood since 1955.
The Seaman 30 is a very 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. The fuel capacity is originally small. There is a very short water supply range.
