I recently purchased a 1984 Ozark tri hull. This is my first boat. It has the back to back seats in it.The metal hinges broke on three of them the first use. One was already broke. What is the purpose of the hinged seats is it to use the storage under seats? If so it looks like to repair them by solidly connecting them would be better. or posiably with a heavier hinge, all of the wood and upolstry is exellent shape.
