Hi I'm new here but I have a question. I recently bought a 16' jon boat for a real good deal but the guy who had it before me cut the back 2/3 of the ribs about an inch after they start angling up onto the sides of the boat. He then put an aluminum and plywood floor in and attached it with rivets to the side hull. As can be expected the plywood rotted and the floor had to be taken out and now all thats left is the ribs. The ribs are in good shape except they don't have the top part that goes up the side (cut off about an inch after the turn up). My question is can i fabricate and add on ends to the ribs? And how should I attach them to the ribs weld or rivet? Is this fixable? Theres no middle bench so I have to add some structural stability. Thanks so much for your help and sorry this is so long.
