1989 Blue Seas 31 Out Island

Annapolis, Maryland


The Blue Seas Out Island 31 is a Royal Lowell designed, Canadian-built Downeast that hits high marks in comfort and functionality. Her single Cummins diesel will cruise you at 10 knots while sipping fuel, and with a semi-displacement hull design with a moderate flare you will ride along nicely. This is the perfect boat for cruising on the bay or taking a trip down the ICW.
