How to Build a Wakeboard Fun Box

Wakeboarders use a flat or inclined box, referred to as a fun box, to perform slides. The wakeboarder jumps onto the top of the fun box while the bottom of his board slides across it. Professionally built wakeboard parks feature the fun box design for both the novice and experienced wakeboarder. Beginners usually stick to the flat fun box design while the more experienced riders can slide across a pyramid-shaped design. Building a homemade fun box remains a good way for riders to learn the basics of sliding in a more private setting than the public wakeboard park.

Instructions

    • 1

      Lay one of the two-by-four pieces of lumber on the ground with it standing on its 2-inch edge. Lay another piece of two-by-four on its 2-inch edge parallel to the first one. Space the two pieces of 2-by-4 4 feet apart.

    • 2

      Cut a third piece of the two-by-four in half to create two identical 4-foot-long pieces. Create a rectangular-shaped box by placing one of the 4-foot pieces of 2-by-4, sitting on its 2-inch edge, on either end of the two parallel pieces of two-by-four.

    • 3

      Connect the rectangular box by hammering two nails into each side of the 4-foot-long pieces of 2-by-4 that make up the width of the rectangular box. Cut the remaining two 2-by-4s in half to create four identical 4-foot-long supports for the rectangular box. Discard the fourth support.

    • 4

      Place three of the 4-foot-long supports between the 8-foot-long two-by-fours that make up the length of the rectangular box. Space the supports 2 feet apart and hammer two nails into each side. Lay the sheet of plywood on top of the rectangular box. Hammer one nail every 6 inches along the outside edge of the plywood to secure it to the rectangular-shaped box.

      Flip the box over. Apply caulk onto the bottom of the sheet of plywood between the 4-foot-long supports. Cut the sheet of Styrofoam into four identical pieces. Place one piece of Styrofoam between each two-by-four support and onto the caulk. Allow the caulk to dry. Flip the rectangular box over and place it in the water to ensure it floats.
