George: I'm wondering about the "satin" lightweight glass you use, multi-layer. Do you have any data on peformance of several layers of light glass (being stronger than an equivalent weight of heavy glass)? Obviously more work to put on, but perhaps easier to control the effects. Why kevlar inside the boat?
