You can still hear the sneer in L.F. Herreshoffs words. I was reading that Ray Greene after building a polyester and glass dinghy in 1942, was commissioned by the US Navy for 2, 28' launches.

At that time, the state of the art production wooden boat process would have required 6 men, 360 hours the same launch hulls. Ray Greenes molded hulls(after the plug was built I assume...) were hot off the molds and ready to finish in 6 hours!

Herreshoffs sneer was that this stuff wouldn't last. He would roll over in his grave today looking at these hulls 50 years later, still sound.
