Notes: Clark Boat Co. had previously built a number of One-Design Dinghy's, but this was the first 'SAN JUAN' and a huge success.\nDesigned displacement was 1250 lbs. but it was found that most ended up at 1400 lbs.\nThanks to Samuel Tricky for providing corrected information for this and number of other boats in this category.
