This is how to make a hollow wooden kiteboard from marine plywood. The design and construction of this board has been simplified as much as possible to facilitate quick, cheap construction with out specialised tools.
The board consists of three layers of wood laminated together to form the core of the board. The centre lamination is not solid in order to reduce the weight of the board without compromising the strength too much.
This style of board is known as a directional , it is designed to be ridden in one direction only and must be gybed or tacked similar to a windsurf board in order to go in the opposite direction. This requires practice and is not best suited to a beginner. The benefits of this style of board is that it does not require any design compromises, you can have huge fin area at one end (for pointing up wind and loading up for jump)s and plenty of nose rocker in the other end for riding in choppy or surf conditions.
