General Description

The F-31 is available in two different versions: the aft cabin model and the aft cockpit model. The aft cockpit model has an open and longer cockpit in place of the aft cabin, and the main cabin is also larger and features an interior configuration that easily converts from day to night requirements; a table and extra bunk slide completely out of the way when not in use. Accommodations for five. Interior features six-foot, two-inch standing headroom, a large double V-berth forward, an enclosed head, and a galley area with sink and a large molded countertop. Large storage compartments in each float augment the plentiful storage in the cabins. The cockpit seats six adults, though this is seldom necessary as the broad decks and nets give the crew many other comfortable places to spread out and relax. The forward hull shape effectively deflects spray away from the cockpit, and winches, halyards and sheets, and the controls for the daggerboard, rudder, and outboard motor can all be operated from the cockpit. A transom swim platform provides easy access on and off the boat. The fractional rotating rig is very efficient and easy to handle in all conditions The fully battened mainsail has slab or jiffy reefing on the aft-cockpit model. An asymmetrical spinnaker flown from the bowsprit enhances off-wind performance. A foil shapped daggerboard provides efficient windward performance; this, along with the kickup rudder, enables the F-31 to moor in very shallow water or even be beached.
