San Juan 34
Description
The San Juan 34 is a robust masthead sloop designed by Hein Driehuyzen in collaboration with Don Clark, marking the largest model in the Clark Boat Company's San Juan lineup. Originally tooled as the Canadian-built Crown 34 by Calgan Marine before molds were acquired by Clark in 1980, it was produced until 1986 with around 50 units built. This racer-cruiser emphasizes speed and seaworthiness with a fin keel and spade rudder, drawing from IOR influences for competitive PHRF racing while offering solid coastal cruising capabilities.
