Sand prep stbd mid riser and floor for biax

The final fillet and biax will now be laminated, and an additional strip of biax up to the keel fillet. Same will be done to the other side of the keel fillet, so that the entire floor is biaxed. Unnecessary, but a decision based on crew and walking in the boat when it is not in the water, and lots of trailering.
BTW, final seattops were only one panel thick, and NOT two as in this picture, glassed both sides and plenty stiff when bonded to the mid batten.
