Home built Formula 16 cats are not uncommon and are frequently built with epoxy coated marine plywood. In some ways the ply core is superior to a foam core. Ply boats are very stiff and strong. Phill Brander has recently developed an updated version of his F16 Blade design that is designed specifically to be home built of ply. I am in the planning stages of building one myself. F16s can easily be sailed 1-up or 2-up. They have a minimum weight of about 230 lbs and ~200 feet of sail with a main and jib. They are the ultimate cat in my opinion.
Some pictures of Phill Brander's first Razor are here:
