My Checkmate Predictor project seems to have 1 small stringer down the middle surrounded by foam.. I am thinking that it would be better to have 2 stringers that go to knees on the transom that are on the sides of the pad and ditch the foam. Most likely raise the floor a bit to get some more height on the stringers. I have seen a couple guys on here do up their Hydrostreams like this. Going to hang a merc 2.5 v6.. thoughts? If anyone has pics of different layouts I am curious as to extra bulkheads and what not to stiffen the bottom outside the pad
