## Design

The Beneteau 331 is a recreational keelboat, built predominantly of solid fiberglass with the deck balsa-cored. It has a masthead sloop rig, aluminum spars, a deck-stepped mast, a raked stem, a walk-through reverse transom, an internally mounted spade-type rudder controlled by a wheel and a fixed fin keel, shoal draft keel or lifting keel. It can be equipped with a spinnaker of 850 sq ft (79 m$^2$).
The interior layouts vary, based on the model and role, but a typical layout has sleeping accommodation for four to six people, with a double "V"-berth in the bow cabin, two straight settees in the main cabin around a drop-leaf table and an aft cabin with a double berth. The galley is located on the port side just forward of the companionway ladder. The galley is U-shaped and is equipped with a two-burner stove, 39.6 U.S. gallons (150 L; 33.0 imp gal) icebox and a single sink. A navigation station is forward of the galley, on the port side. The head is located opposite the galley on the starboard side and includes a shower. A three-cabin layout was also available.
Headroom is 74 in (188 cm) in the galley and head, 74 in (188 cm) in the main and aft cabins and 73 in (185 cm) in the bow cabin.
The design has a hull speed of 7.40 kn (14 km/h).
