I overbuilt a storage/extra front deckspace onto my 1860 G3 a while back, finally learned how to post pics so here are a few. I used an aluminum highway sign for the top and front, and varnished the untreated pine 2x4/2x6 for the framing, liquid nails between the hull and the top frame pieces,galvanized brackets to rivet some of the frame to the boat and stainless screws/washers and cheap gate hinges. Top is sprayed w bedliner. It is very strong and I think it has made the boat less twisty too!! My homeaid PVC outrigger is in one shot!
