Wooden Flat Bottom Boat - How to Build a Wooden Flat Bottom Boat

A flat bottom boat is easy to make and is one of the safest boats, as it is not readily overturned. It has the advantage of being rowed from either end, and has plenty of good seating capacity.
This punt, as shown in Fig. 1, is built 15 ft. long, about 20 in. deep and 4 ft. wide.
The ends are cut sloping for about 20 in. back and under.
The sides are each made up from boards held together with battens on the inside of the boat near the ends and in the middle.
One wide board should be used for the bottom piece. Two pins are driven in the top board of each side to serve as oarlocks.
The bottom is covered with matched boards not over 5 in. wide.
These pieces are placed together as closely as possible, using white lead between the joints and nailing them to the edges of the side boards and to a keel strip that runs the length of the punt, as shown in Fig. 2.
Before nailing the boards place lamp wicking between them and the edges of the side boards.
Only galvanized nails should be used.
In order to make the punt perfectly watertight it is best to use the driest lumber obtainable.
At one end of the punt a skag and a rudder can be attached as shown in Fig. 3.
