We build solid glass hulls and offer foam and balsa coring options.

Solid No water problems within hull. Inexpensive and easy to repair. Somewhat more prone to condensation/sweating inside.
Foam Core No sweating. A stiff, quiet boat in the water. Lightweight and possibly faster. Water damage is possible. Expensive option and expensive to repair.
Balsa Core No sweating. Also stiff and quiet in the water. Less expensive than foam. Lightweight and possibly faster. Water damage possible and balsa will rot. More expensive to repair than a solid glass hull.

A foam or balsa cored hull will not have water problems if they are well constructed, and we guarantee quality construction.
