Fishermen in Friendship and neighboring Bremen collectively originated the boat's design, influenced in part, by the fishing sailboats of Gloucester, Massachusetts.
[3] One person could manage its single-masted rig and haul traps unassisted, yet the boat could carry sizable loads.
[6] Friendship sloops typically have a clipper bow, a full keel, an elliptical stern and a bowsprit.
The mast height is approximately equal to the length of the deck and stepped forward, such that the head sails are attached to the bowsprit.
The hull typically has a full length keel, traditionally ballasted with rocks or more recently with steel.
