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.
