The MV Bluebird is undergoing seat trials on Lake Victoria now. It is built from developed plywood/epoxy, with lots of core on flat surfaces. The whole thing went over in several containers after it was built near Seattle. I will be offering an option that is not quite as wide and a little lighter also.
