The Sea Bird 37 is a recreational keelboat, built predominantly of fibreglass, with wood trim. It was built with a choice of either a ketch or masthead sloop rig and an aft or centre cockpit. The boat has a raked stem, a nearly plumb transom, a/an keel-mounted rudder controlled by a wheel and a fixed long keel. It displaces 18,000 lb (8,165 kg) and carries 6,000 lb (2,722 kg) of ballast.[1][2]
The boat has a draft of 4.00 ft (1.22 m) with the standard long keel.[1][2]
The boat is fitted with a British Perkins Engines 4-108 diesel engine of 40 hp (30 kW) for docking and manoeuvring. The fuel tank holds 100 U.S. gallons (380 L; 83 imp gal) and the fresh water tank has a capacity of 80 U.S. gallons (300 L; 67 imp gal).[1][2]
The centre cockpit version has sleeping accommodation for six people, with two single berths in the bow cabin, a drop-down dinette table in the main cabin and an aft cabin with a transverse double berth. The galley is located on the starboard side just forward of the companionway ladder. The galley is U-shaped and is equipped with a two-burner stove, an ice box and a sink. There are two heads, one in the forepeak, forward of the bow cabin and one on the starboard side in the aft cabin.[1][2]
The design has a hull speed of 7.64 kn (14.15 km/h).[2]
