Windsurfing Boom
The windsurfing boom is a piece of equipment that attaches to the mast of the windsurfer which is in turn attached to the board. The boom can freely move with the sail and mast independently of the board. The boom goes all the way around the sail so the rider can grip it from both sides which is essential for windsurfing.
A windsurfing boom can be made from a variety of materials. Aluminum is used on the lower end because it is very affordable while still being relatively light and corrosion resistant. Various alloys can be used as well as carbon fiber and other synthetic materials to increase the stiffness as well as decreasing the weight.
The windsurfing boom has to be as still as the mast for best results. An excessively bendy boom can made windsurfing more difficult as the energy is transferred less consistently. The boom effectively transfers the rider’s energy to the sail and mast which maneuvers the board. With a harness the rider has to exert even less effort.
