I have a boat that is subject to the abuse of hitting rocks and sometimes boulders. the current hull is built out of 0.105" mild steel and i end up with cupping and dents in the hull. i was wondering if the extra density of 3 laminated layers of 3/8" fir plywood would work better.. Marine plywood is a great sheet material that can be easily cut using both hand saws and basic power tools. marine plywood is often used to build boat interiors and to replace flooring during boat renovations..
As you can see from the pictures, the boat does okay. it is by no means a speed boat or a stable boat but it is fun and it can displace quite a bit of water (held about 400 pounds and still had just over an inch of freeboard). this is a much better boat for someone my son's size and handled quite well.. With myself, my wife, our dog and the boat we'll weigh about 400 and the draft will be 4.8". not too terrible for playing around. a small stern deck of 1/8" ply wouldn't add much weight and allow you to lower it into the water by it's bow line, off a boat or dock without taking any water on board.. 4' (ft) x 8'6" (ft) size sheets available 7 ply - 3/4" thick marine plywood; designed for rigorous marine use. cca treated and kiln dried marine plywood. great for boats and/or other exterior uses..
