Cut the A/B marine plywood panels lengthwise.
Set the circular saw to cut just past the depth of the panels for the cleanest cut.
This is how our CHIP's panels were key scarfed, we will try to duplicate that.
Scarf was about 1 1/2 inches long on each panel. Made several passes with the circular saw at 1/16th inch to cut away the bulk of the scarf, then cleaned it up the jack plane, finger plane and rabbet plane.
The plywood is A/B, meaning there is a nicer side with with fewer patches. This B side had several patches. Marine grade plywood has more veneer layers and is glued together with waterproof glue. The A side can have patches also, just fewer of them, they are faired with putty and sanded.
Used the old keel strip to set the spacing on the bottom panels. Tacked the bottom down with ring shank nails and strapped the bow and stern down to pre set some bend.
The Sunfish keel strip was not as deep because that hull has a deeper V. It also overlapped the panel edges. We will make the new keel strip for ZSA ZSA deeper so she will track better, with the overlap to protect the panel edges and help seal up the keel seams.
