The Swan 46 Mk II is a Finnish sailboat that was designed by Germán Frers as a cruiser-racer and first built in 1989.[1][2][3][4][5][6][7]

The Swan 46 Mk II is a development of the Swan 46 Mk I with a modified keel and other changes.[1][2][3]

Production

The design was built by Oy Nautor AB in Finland, from 1989 to 1997 with 28 boats completed, but it is now out of production.[1][2][3][8][9]

Design

The Swan 46 Mk II is a recreational keelboat, built predominantly of glassfibre, with wood trim. It has a masthead sloop rig, a raked stem, a reverse transom, an internally mounted spade-type rudder controlled by a wheel and a fixed fin keel with a weighted bulb or optional stub keel and retractable centreboard. It displaces 31,300 lb (14,197 kg) and carries 11,400 lb (5,171 kg) of lead ballast.[1][2][3]

The keel-equipped version of the boat has a draft of 8.20 ft (2.50 m), while the centreboard-equipped version has a draft of 9.0 ft (2.7 m) with the centreboard extended and 5.5 ft (1.7 m) with it retracted, allowing operation in shallow water.[1][2][3]

The boat is fitted with a British Perkins Engines diesel engine of 50 hp (37 kW) for docking and manoeuvring. The fuel tank holds 99 U.S. gallons (370 L; 82 imp gal) and the fresh water tank has a capacity of 127 U.S. gallons (480 L; 106 imp gal).[1][2][3]

The design has sleeping accommodation for six people, with an off-set double berth in the bow cabin, two straight settees in the main cabin, along with a pilot berth and an aft cabin with a central double island berth. The galley is located on the port side just forward of the companionway ladder. The galley is of straight configuration and is equipped with a three-burner stove, an ice box and a double sink. A navigation station is opposite the galley, on the starboard side. There are two heads, one in the bow cabin on the port side and one on the starboard side aft.[1][2][3]

The design has a hull speed of 8.24 kn (15.26 km/h) and a PHRF handicap of 54 to 63 with the fin keel.[1][2][3][10]
