Hi Roy. This is one of the great things about having a Roplene hull. This repair is not that difficult to fix and I'm sure the damage is much less than a fiberglass hull would have had. You can get Roplene "welding rods" from your Triumph Dealer and use a Plastic welding gun to heat it up and work it into place. Then a triming tool and a little sanding will smooth it out. Triumph hulls are the same color thru out so you only need to get the correct model year color welding rods. I would check with your dealer about fixing the gouges for you. If you don't have a dealer you can contact
Merritt Marine in NC and order the rods (and the welder) from them. I have a section of the Triumph Boats Maintenance and Modifications DVD that I'm working on that shows how to do this. I'm still working on it and hope to have it done this month.
