As you can see from the drawing, the keel box forms an open beam when laminated to the 3/4 pine, then to the floor, then to the hull... a series of triangles.
The keel box is formed from layers of woven roving and has a, IMHO, serious flaw, there is no shear support. The strands of the roving run with the joints and across the joints of the floor to hull bond so the only shear is from the resin.... not that strong.
I'm going to correct this defect by using 4 layers of 17 oz. bi-axial tape staggered up and across from the bottom of the keel box to the outside edge of the white pine. Glue the floor to the pine boards, radius the floor to the hull with a putty made of thixotropic powder, chopped strand, and epoxy. 4 layers of 17 oz. bi-axial tape, then an overlay of 12 oz. bi-axial cloth across floor and up the sides of hull to hull/top split.
