33' International One Design - $35000 (San Francisco)

IOD SF for sale

The International One Design was inspired by a Six Metre created by the famous Norwegian architect and builder Bjarne Aas, in 1935. Cornelius Shields, Sr., impressed by her beauty and handling qualities, initiated action for an entire Class similar in design and appearance, but with a loftier rig and a short shelter and storage cabin. Aas submitted plans and specifications in 1936 and a syndicate was formed. The International One Design San Francisco Bay Fleet followed and has been active since 1954. 

This boat is fiberglass built by Aas in 1970, fully equipped and race ready. She's in very good condition with two full sets of sails. And she has a berth in the West Harbor of the San Francisco Marina and can quite likely remain there after sale.
