Design
editThe Swan 431 is a recreational keelboat, built predominantly of glassfibre, with wood trim. It has a masthead sloop rig, a raked stem, a reverse transom, a skeg-mounted rudder controlled by a wheel and a fixed swept fin keel. It displaces 26,500 lb (12,020 kg) and carries 11,900 lb (5,398 kg) of ballast.[1][2]
The boat has a draft of 7.40 ft (2.26 m) with the standard keel.[1][2]
The boat is fitted with a British Perkins Engines 4-108M diesel engine of 37 hp (28 kW) for docking and manoeuvring. The fuel tank holds 40 U.S. gallons (150 L; 33 imp gal) and the fresh water tank has a capacity of 100 U.S. gallons (380 L; 83 imp gal).[1][2]
The design has sleeping accommodation for nine people, with a double "V"-berth in the bow cabin, two straight settee berths and two pilot berths in the main cabin and two aft cabins with a double berth in the starboard cabin and a single berth in the port cabin. The galley is located on the port side just abeam of the companionway ladder. The galley is of straight configuration and is equipped with a three-burner stove, an ice box and a sink. A navigation station is opposite the galley, on the starboard side. There are two heads, one just aft of the bow cabin on the port side and one on the starboard side aft.[1][2]
The design has a hull speed of 7.74 kn (14.33 km/h) and a PHRF handicap of 84 to 93.[1][2][7]
