Design and Construction
The hull is solid fiberglass, and the boat carries 3,400 pounds of ballast against a displacement of 10,250 pounds for a 33 percent ballast ratio anchor. Her 25.58-foot waterline and 11-foot beam give a length-to-beam ratio of 2.69, while a displacement-to-length ratio of 273 by the builder's figures — and 320 per one period analysis — places her firmly among heavy cruisers anchor. The long-keel configuration with rudder on skeg is a conservative underwater profile that favors directional stability over quick turning. A capsize screening value of 2.00 to 2.03 and a comfort ratio in the mid-20s describe a stable, forgiving platform.
Rig and Handling
As a masthead sloop she carries a reported 419 square feet of sail area, and her sail-area-to-displacement ratio sits at 14.21 by the manufacturer's numbers. Writing in yachtdatabase, one period review found her significantly overrigged, carrying more rig than 96 percent of comparable sailboats, with a 135 percent genoa lifting the SA/D to 13.3 anchor. Her wetted surface is about 290 square feet. The shallow 3.5-foot draft lets her tuck into marinas that deeper keelboats cannot reach. Halyard and sheet specifications are generous: mainsail and genoa halyards run 82.5 feet at 3/8 inch, while the mainsheet is 77.5 feet of 1/2 inch line. Her theoretical hull speed is 6.78 knots.
Accommodations
The pilothouse layout gives the boat its name and its appeal, with 6.5 feet of headroom below. Tankage is modest but adequate for weekend and coastal cruising: 30 gallons of diesel and 60 gallons of water. A single 15-horsepower Yanmar diesel provides auxiliary propulsion. The proportions suggest a compact but livable interior centered on the protected helm and companionway below.
The Verdict
The Pilothouse 31 is a modest, heavily built coastal cruiser with a shallow draft and a surprising amount of sail for her displacement. She suits a buyer who values a protected helm and simple systems over performance or volume.
Pros
- Shallow 3.5-foot draft eases marina and gunkhole access
- Heavy-cruiser displacement and 33 percent ballast ratio aid stability
- Generous sail plan for a 31-footer
- Pilothouse configuration protects the helm
Cons
- Modest 15 hp auxiliary and 30-gallon fuel capacity limit range under power
- Long-keel format trades maneuverability for tracking
- Overrigged status may overwhelm short-handed crews
