Use the 2 step easy boat opener to assist with opening the boat while you install the seats. Place your hand in the hand grip area of the opener while you place the hook end on to the gunnel tube near the oar lock socket. With the other hand grasp the other side of the hull by the gunnel tube and pull back towards you just enough to secure the hook section in the middle of the opener on the other gunnel near the oar lock socket. While on the outside of the boat, regrip the hull by the same gunnel tube and the opener with the other hand and spread the boat just enough to secure the third hook on to the gunnel. You are now ready to install the middle seat. See instructions for seat and transom installation.
