Lay two 1 1/2-by-3 1/2-by-18-inch boards on the working surface, parallel to each other with their wide surfaces touching the working surface. Set two more parallel 1 1/2-by-3 1/2-by-18-inch boards on top of them, but perpendicular to the original two boards.
Arrange the four boards so they form a perfect square, with the boards overlapping evenly in the corners.
Drill four holes into each corner, down through both boards. Set galvanized 2 1/2-inch screws into each hole and tighten them with a drill.
Repeat for another set of four boards to create two identical squares of boards, which will be used as the legs of the bench.
Stand up the two legs with the help of an assistant, and set two evenly spaced 1 1/2-by-3 1/2-by-36-inch seat boards on top of the legs, with the large flat side of the long boards touching the top surface of the legs. Arrange the legs so that they are about 2 inches from the end of the seat boards.
Drill four holes down through each long board into each leg board. Attach the seat boards to the leg boards with 2 1/2-inch wood screws.
Position two 1 1/2-by-3 1/2-by-48-inch backrest boards on their smallest ends at the rear of the bench, so that their largest flat sides are flush up against the legs of the bench. Pre-drill six holes through the back of each backrest board and into the legs.
Attach the backrest boards to the legs with 2 1/2-inch wood screws.
Position a wakeboard on the seat of the bench with the curve of the board bending downward. Drill two holes through the board and into each seat board.
Attach the wakeboard to the seat board with galvanized 4-inch wood screws. Repeat for the backrest wakeboard.
