SSV Corwith Cramer

Corwith Cramer, named after SEA’s founding director, was designed by Wooden and Marean specifically for SEA and was constructed by ASTACE Shipyard in 1987 in Bilbao, Spain. She is a 134-foot steel brigantine built as a research vessel for operation under sail. The qualities that made our original vessel R/V Westward both versatile and seaworthy were incorporated into the design of SSV Corwith Cramer.

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.
