The piers are 4 inch squares of left over Coosa from the transom laminated together with a layer of mat in between each layer. I used 4 pieces of 1708 on each vertical plane of the pier after I bedded the piers in thickened resin. The "horns" ar to keep the tank from moving forward. They are mostly gassed in. I'm not finished. Probably will give another layer of 1708 or 2 all around. Where the tank's dog ears (?) mount to the stringers I have added 3 more layers of 1708 or will. There will be a total of at least 5 layers of 1708 plus multiple layers of mat. Should be pretty stout
