Yes, Howie. The canvas is lapped over the transom and stapled. The Tim get bedded and fastened over the overlap. I mill out a little bit on the trim to fit over the canvas. Some square sterns have a rabbet milled in the transom. In that case, I bed the rabbet and fold about a half inch of canvas over to fit in the rabbet and staple.....no overlap. As far as weight goes, I may have suggested a trailer to Shari previously. In that case weight doesn’t matter. Even without sponsons, this craft will be heavy. Unless Shari is getting younger and stronger, I’d suggest not cartopping it. I have only rowed square sterns with sponsons. I can’t attest to the stability. They are not that tough to canvas......and the look cool on this boat!
