Several months ago someone on the forum was looking for plans for a "wooden sunfish". The authro indicated that the plans were in Popular Science in 1949. He indicated that they were out of print and that Popular Science only had one copy and wouldn't make a copy as it was not acid free paper and would be destroyed.
I have access to a library with hard copy of
Popular Science for the yedar in question. However, there were no plans for a wooden sunfish in 1949, or 1947 - 1953. In the March 1951 issue there was a set of plans for "Solution: A 16 ft. Plywood Sailing Scow". I made a copy of the article and have the plans is anyone is interested.
Then, two days ago I searched Reader's Guide to Periodic Literature. I recalled that the Sunfish by Vanguard was celebrating its 25th anniversary. I looked in the 1975 index and found the plans for "Sailfish" a wooden replica of Vanguard's Sunfish. It was in Mechanics Illustrated, volume 71, pages 40-42 of the August, 1975 issue. I made a copy of this as well and would be willing to share it.
The "Sailfish" is the older design, 13 ft., 46 inches wide, inset cockpit, weighs 186 lbs. (according to the author who used 3/8 inch plywood) and uses the Sunfish rig from Vanguard.
Hope this is helpful and, again, contact me it you have any desire for either articles.
