    And I have a few questions

    What wood would work best? Normal plywood or what?

    Type of wood? Oak, waulnut, cherry or pine or what?

    What brands of fiberglass resin?

    Special screws or would decking screws work?

    How to seal the joints?

    Local hardware store have all this?

    First Ill make templates for all the pieces.

    Thanks in advance Ill post my build once I complete it.

    This is what I trying to attempt.

    I can think of a least a few dozen different types of plywood alone and several dozen different solid wood species, each with different physical properties. You typically select the one best suited, for the needs and tasks it'll be asked to carry.

    Any of the major resin brands will work fine, though some are more suited and less costly then others. None is a hands down, get it done kind of thing.

    Sometimes you can use decking screws, but not very often. Stainless and bronze are most common, with galvanized used in boats not intended to last very long.

    Joints can be sealed in (again) one of several ways, typically they're application specific.

    You'd be very lucky to find a hardware store that has a small percentage of the materials you need.

    Templates are a good idea, but you really need none of the above, as much as you do a bit of research and study into the materials, techniques and methods employed in boat building. A short brush up of hydrodynamics, some light engineering and general building techniques is also in order too. Buying a set of plans would be the easy and wise option. The materials will be listed and often you'll get a basic instruction manual too. What is that thing? It looks like a big slipper in the photo, but maybe it's a scow or really fat kayak.

    Have you checked on the legality of that? I was under the impression they were frowned upon by the authorities in some states.

    Gee, the boat you have pictured is very unigue. It must be a gunning float ? The shape is not easily built of wood.

    Investigate mold making and the use of fiberglass.

    Perhaps an inflatable bladder. Form it to a suitable shape then glass over.


    Perhaps a huge block of stryofoam...carve to the correct shape, glass over...remove foam.

    The cheapest way to get one like the picture is to just buy it. But you can built a much simpler design from plywood. Since it has limited use no reason to use costly boat building materials, you can build something similar, but with hard corners, out of 1/4" fir extirior plywood. I think I would use skin-on-frame construction, like a sea kayak. You can even make it with a folding frame.

    Buy some clear doug fir planks, rip it into stringers, use plywood for bulk heads, and lash it all together with poleyster artificail sinew. Than cover it with heavy 10 or 12 oz canvas, polyester or nylon and put 5 or 6 coats of oil based paint on it. YOu can built it this way for about $100 worth of materials, should be light weight and easy to build. But it will have "hard lines" rather than smooth compound curved surfaces. But with a good camo paint job the hard lines will not hardly show up.

    I have built over 12 skin-on-frame boats, mostly kayaks, but also several small sail boats, and all have held up fine for years.
