The Express 37 is an American light displacement sailboat designed by Carl Schumacher as a racer-cruiser.[1][2][3]
The design was built by Alsberg Brothers Boatworks in Santa Cruz, California from 1984 to 1988, but is now out of production. A total of 65 were completed.[2][4]
Design
The Express 37 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a reverse transom, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel. It displaces 9,800 lb (4,445 kg) and carries 4,600 lb (2,087 kg) of lead ballast.[2]
The boat has a draft of 7.25 ft (2.21 m) with the standard keel fitted. The later Mk II model offered an optional shallow draft keel of 5.92 ft (1.80 m).[2]
The first 25 boats built were fitted with a Japanese Yanmar 2GMF two cylinder diesel engine of 18 hp (13 kW). Later boats had a three-cylinder Yanmar 3GMF diesel engine of 27 hp (20 kW). The fuel tank holds 30 U.S. gallons (110 L; 25 imp gal) and the fresh water tank has a capacity of 85 U.S. gallons (320 L; 71 imp gal).[2][5]
The later Mk II version has a taller rig, an updated keel and rudder and a more cruising oriented interior. Only ten were built in this configuration.[5]
