Boomkicker

A boomkicker [1][2] is a modern mechanical device on boats that pushes the boom up by one or more glassfiber rods.

If the boom is sheeted in, the rods will bend and produce a force upwards.

In light air, a boomkicker provides better sail shape by lifting the boom and opening the leech.

A boomkicker may be installed alongside a traditional block and tackle boom vang, and will work in close collaboration with it.

The boomkicker is, among others, widely used on the International Dragon Class.
