The Express 37 is an American light displacement sailboat designed by Carl Schumacher as a racer-cruiser.[1][2][3]

Production

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]

Operational history

The Express 37 finished first, second and third in its debut at the 1985 Transpacific Yacht Race.[5][6]

In a 2005 used boat review in Sailing Magazine, writer John Kretschmer concluded of the design, "The Express 37 offers exhilarating performance both on and off the racecourse. And although one-design fleets are shrinking, most 37s have a lot of speed left in them. Also, following the trend of their boats, as racing sailors get older and migrate toward more casual sailing, a logical decision might be to convert a 37 into more of a cruising boat."[5]

Marine surveyor and naval architect, Jack Hornor described the design in a 2007 review, "the Express 37 will appeal to sailors interested in racing more than the dedicated cruiser; although, there is no reason these mid-1980s models can’t serve double duty for prospective buyers looking for a reasonably priced, solidly constructed racer/cruiser...Although contemporary in appearance, Schumacher’s respect for the beauty of traditional, well balanced boats is apparent in this design."[6]
