SSV Robert C Seamans

SEA’s newest vessel was designed by Laurent Giles of Hampshire England, and built at JM Martinac shipbuilding in Tacoma, Washington. Named after former trustee and Chairman of SEA’s board, the Robert C. Seamans is a 134-foot steel brigantine and is the most sophisticated oceanographic research/sailing school vessel ever built in the United States. Improvements in design and equipment, including a wet/dry laboratory and larger library, classroom, and computer laboratory, enhance the SEA academic program.

SEA vessels fly the United States flag and are inspected and certified by the United States Coast Guard as Sailing School Vessels (SSV). Sailing School Vessels are required to meet stringent safety standards that differ from those of a passenger vessel on a comparable route. All SEA vessels meet or exceed the safety requirements for their class.
