Above: Marine-grade plywood basics include knowing how to select marine-grade plywood for flexibility vs. stiffness. This wing mast required plywood with some flexibility.
Since so many projects in Epoxyworks incorporate plywood, we felt it might be valuable to discuss briefly the types of marine-grade plywood and some construction methods best suited to it. It’s easy to understand why people like plywood and choose it for so many projects: it is readily available, comes in convenient sheets (typically 4’×8′), is pretty light for its stiffness and strength (1/8″ plywood weighs about 11 lb per 32 sq ft panel), and is a bargain when compared to the price of many composite panels.

There are those who still question the longevity of an epoxy composite structure. They state that the technology is still too new to know how it will hold up long-term. Some have said that epoxy composites fail in the tropic heat; other critics have warned of the hazards of wood and freshwater. However, I’ve recently visited several boats that are living testimony to the long-term reliability of epoxy composites. Of course, careful construction and good Continue reading →
Boats are my first love, but I get excited about projects like this Supermileage® vehicle, other SAE (Society of Automotive Engineers) and airfoil carved-foam bicycle. My job offers great opportunities to talk to some of the most talented and positive thinking people around: sculptors, inventors, rocket builders, and good ol’ boatbuilders. Folks who envision and tinker with a desire to experiment, improve, compete, make a living or just play around. Continue reading →
