Balsa cored hulls - old boats
Our present boat, Teacher''s Pet III was one of the first balsa cored boats, we had to import the logs and have a mill cut the strips for the hull, not like the squares.
She was built in the 1968-69 period. The resin was very good then. She has never had a leak and when surveyed the surveyor said she was in better condition then any boat of the same period he had surveyed. Balsa Core is O.K., maybe even good, our boagt does not sweat, is dry, cool in the heat and easy to heat when its cold. I get tired of hearing "experts". except for Jeff H shooting their mouths off.
