The boat has a rolled edge, and at the stern there is a small lip, 11" on each side, that tabs back. Would it be okay to cut those away flush with the transom? I'm thinking it'll be easier to wrap the glass around the transom. I realize they're there for rigidity, but a new transom should be plenty stiff....no? Or should I wrap the glass up on to the tabs....then over in the middle section? The transom will be two pieces of 3/4" marine ply. Thanks.
