I have read about the System Three, I was looking a Glen-L years ago and have picked up a couple of study plans for ones I liked. I think they sold out to another company and transferred operations up to Washington. They still have the Glen-L plans. They have a gathering in Eastern Tennessee in the Fall where the home builders show off their builds. I need to go check it out sometime.
Never knew that abut the Matt, maybe I meant the cloth. The Strip Plank Kayaks use a 4 oz cloth to seal the exterior. Sounds like I need to start planning a Kayak build, have 2 books from Nick Shade which includes the table of offset for 3 different models.
My brother always said start small.
