How strong is the fiberglass stringer system?
If manufactured and installed correctly, a stringer grid made of fiberglass can be extremely strong. The stringers made by Jones Brothers use a LOT of glass, and are very strong on their own. When installed, the stringer grid has a great deal of contact surface with the hull – much more than a typical wood stringer grid. Additional glass is added to bond the entire edge of the stringer to the hull. Foam is then injected into all cavities for additional strength and rigidity, as well as flotation. Once the floor is glued on top of the stringer grid, the boat is solid.
