Hi Peter, those are Gary's pics and they are indeed nice. With the small volume foam/glass ama, which I made according to size for a 24' Wa'apa, CofG stays low enough to be stable. I made a larger foam/glass ama, about three times the volume, and it is too heavy to ride up in the air. I go no more than 60 mph. The trip to Waldo Lake this year was a 7 hr. drive and no problems. My trailer is a Harbor Freight with a longer stem? tongue? swapped in. It needed a cradle for the front of the hull to be strapped to, otherwise that stem noodles around too much.
My cedar strips were accidentally cut shy of 1/8" so I tried to compensate by adding heavier glass. The hull came out at about 110 lbs. if I remember correctly. I ended up adding 3/4" more wood to the inwales this year, and through-bolting the seats to the inwales to make a sort of stiff ladder frame out of it all, this reduced hull twisting. I'm not sure what it weighs now, but I suspect none of that would have been necessary if the strips had been the correct thickness.
