The Hunter 31 is an American sailboat, designed by Cortland Steck and first built in 1983.[1][2][3][4][5]

In 2006 the company introduced a new boat under the same Hunter 31 name, but it is commonly referred to as the Hunter 31-2 or Hunter 30/31 to differentiate it from this design. It is sometimes confused with the 2015 Marlow-Hunter 31.[6][7][8][9]

Production

The Hunter 31 was built by Hunter Marine in the United States between 1983 and 1987, but it is now out of production.[1][5][10]

Design

The Hunter 31 is a small recreational keelboat, built predominantly of fiberglass, with wood trim. It has a reverse transom, a length overall of 31.33 ft (9.5 m), a waterline length of 26.25 ft (8.0 m), displaces 9,700 lb (4,400 kg) and carries 4,000 lb (1,814 kg) of ballast. The boat has a draft of 5.30 ft (1.62 m) with the standard keel and 4.00 ft (1.22 m) with the optional shoal draft keel.[1][5]

The boat is fitted with a Japanese Yanmar diesel engine of 16 hp (12 kW). The fuel tank holds 18 U.S. gallons (68 L; 15 imp gal) and the fresh water tank has a capacity of 33 U.S. gallons (120 L; 27 imp gal).[1][5]

The full keel boat has a PHRF racing average handicap of 168 with a high of 174 and low of 162. The shoal keel version has a PHRF racing average handicap of 171 with a high of 180 and low of 162. Both models have hull speeds of 6.87 kn (12.72 km/h).[1][2][3][5]
