The hull is 4 inches longer than Yellow Boat 1 the keel is fiberglass and epoxy as are the chines, everywhere else its hot glue. Much cleaner hull then the earlier boats but still a bit ugly.
These hulls are tough as, run them into rocks do what you like they just flex. I suppose they would fail at the seams when they do, that's why I glassed in the keel.The hull is all one piece of Coroplast split in the front sections and glued. I scored the folds with a ball point pen so they bend correctly, getting better with the material now.

The ride plate is glassed in on the inside so its really stiff, as the pump is all outboard I have recessed the transom to hide it away a bit. Its a big jet unit.

Room for 2 X 11.1V 2200mAh 20C batteries in parallel should deliver up to 80 + Amps
The cooling system is here
