The 31 BLUE SEAS DOWNEAST STYLE EXPLORER was built from true craftsman in Maine at BLUE SEAS MARINE.  The TORTOISE has a semi-displacement built down hull. The boat was built with a full run keel with a protected rudder. The flare of the 31 Blue Seas makes for a dry comfortable ride. The current owner is a knowledgeable seaman and has maintained and cared for his boat.

Broker's Comments

TORTOISE is a very nice well-built very fuel efficient DOWNEAST STYLE boat. It would make a great dive boat or coastal cruiser.
