I purchased a 1977 Sunfish in excellent shape. I read on the web that the hull should weigh between 135-140 pounds. Is this correct? When I weighed my hull it was 183 lbs. So I'm thinking it's water logged. I purchased 2 inspection port covers thinking one up front and one in back and I would use a computer fan to dry it out. But when I cut one hole in the hull, no water and the white foam had no stain marks. Can anyone help me with my question?
The water is soaked up by the yellow foam used as a glue. The white foam (Styrofoam™) is only affected by cut-damage or pressure, which shrinks it somewhat.
