i'm new to boating. found an old alum. boat with 70hp evinrude motor and trailer for $300. it must have 2000 rivets. the farmer said it has been sitting for six years. the hull is sound. no ser. numbers or make, no paperwork. its 20' has a small cabin that you bend over to get inside. going under the dash there is a small hatch between the windshild and bow. the top and sides are alum. has a rap-around windshild, side glass slides back. the back of the cabin is open, there are two bench seats on each side. and a drivers seat. whats odd is the nose or bow' from the nose, the front goes stright down to below the water line. the sides are one piece. the bottom is semi-vee smoothing out to flat in the rear.<br />the boat is built like a tank. has 1" plywood floor boards and 3/4" sides. i have tried everything to find the make. any ideas.
