Boat making process
To cover the boat, you need to prepare plastic barrels with a volume of 200 liters.
Using a grinder, cut off the bottom and neck, then spread them lengthwise into sheets.
In order for the boat to be reliable and have a high carrying capacity, its frame must be made of metal. To do this, you need to take a 10x10 mm square of arbitrary length and bend it at one edge into an arc.
The resulting blank will serve as the keel and stem.On the side, 2 bent strips are welded to it, which will form stringers.
Next, you need to fix the stringers exactly relative to the keel. To do this, you can use rope garters and wooden blocks. Having set the required shape of the boat, you need to weld angle frames between the stringers and the keel. Then a transom frame made of a profile pipe and a corner is welded into the rear of the boat. If you plan to install a motor in the future, then the shape and height of the transom must be calculated according to its parameters.
A corner with cutouts along the edges for a thin profile is welded perpendicular to the top of the keel. Then fender bars from a profile pipe are welded from the transom to the corner on the bow. Between them, closer to the nose, a spacer beam is welded. It can be made from a corner or profile pipe.
To add rigidity to the hull, it is necessary to weld spacers between the bottom frames. This is guaranteed to prevent their deformation under load. Next you need to lengthen the frames with corners to the fender.
To make the boat even stiffer and more comfortable for fishing, you need to expand the fender beam. To do this, a profile pipe is laid parallel to it inside the boat from the transom to the beam and welded with short jumpers using half beams to the beam.
Next, you need to weld the transom frame with sheet steel. Due to this, it will be possible to install any outboard motor on it without fear that it will fall off, so it is better not to use plastic. For rigidity, you can weld a couple of gussets between the transom frame and the fender.
To have a surface for attaching the skin, it is necessary to expand the keel, stringers and fenders. To do this, a strip is added to them. The skeleton of the boat is then carefully painted.
After the paint has dried, it is necessary to cover the frame with plastic sheets from barrels. To do this, the frame is coated with silicone sealant and sheets are laid on it. They are screwed with metal screws. In places on the bow of the boat where it is necessary to bend the plastic, you can first cut out a pattern from cardboard and then cut the skin according to it. All seams between the sheathing must be sealed with sealant. The deck of the boat is also lined with plastic.
After 1-3 days, when the sealant has completely dried according to the instructions, the boat can be launched and tested. If you use thin rolled metal in the manufacture of its frame, the vessel turns out to be quite liftable for two people. If necessary, it can be transported on a truck or trailer. For its full operation, you will need to make a second bottom flooring so as not to stand with your feet on the plastic covering, as it can be torn out. To do this, you can lay boards or plywood on the frame.
