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 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]
