With the remainder of the main float getting buttoned up, it was time to
make ( shape, carve & sand ) the cuff bases to the aft "V" struts and then
sandwich those uprights with balsa and
Sand them to an airfoil shape. Once that was completed, it was time to
finish up the transom by adding the rudder hinge supports, showing the
rudder temporarily in place w/ toothpicks.
