I'm pretty sure it was the first mass produced fiberglass stringer double hull design. It's one of the things they were known for but I know little else about the construction. https://www.speedwake.com/threads/whatever-happened-to-sunrunner-boats.15845/page-5
I've read on some forums that Sun Runner boats were built with fiberglass stringers....etc. I have a 1987 220sb and I have water in the cabin floor area (table post hole) Trying to figure out if I'm dealing with a water logged hole and if I am, is it even a problem with this type of hull...
