The San Juan 34 is an American sailboat, that was originally designed by Canadian Hein Driehuyzen, modified by Don Clark and first built in 1980.[1][2][3]

The San Juan 34 design is a development of the 1975 Crown 34.[1][3]

Production

The Crown 34 was first built by Calgan Marine in North Vancouver, BC, Canada, with 30 examples completed between 1975 and 1979.[1][3][4][5]

After production of the Crown 34 ended in 1979, the molds were sold to GlassFab of Monroe, Washington, United States. That company only built five examples, under the name Sun 1020. The molds were then repossessed by Calgan and later sold to the Clark Boat Company in Kent, Washington. After some modifications, the design became the San Juan 34, which was introduced in 1980 and built until 1986.[1][4][3][6]

Design

The San Juan 34 is a small recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a reverse transom, a skeg-mounted rudder and a fixed fin keel.[1][3]

The boat is fitted with a Japanese Yanmar 3GM diesel engine of 24 hp (18 kW). The fuel tank holds 22 U.S. gallons (83 L; 18 imp gal) and the fresh water tank has a capacity of 50 U.S. gallons (190 L; 42 imp gal).[1][3]

The boat has a hull speed of 7.08 kn (13.11 km/h).[3][7]
