The carbon boom is a horizontal spar attached to the lower part of the mast. Its carbon fiber construction is its primary characteristic. NauticExpo offers a wide range of carbon booms for sailboats of different sizes, roller reefing, etc.
The carbon boom holds the foot of the mainsail. It is usually used on racing sailboats because of its particular properties.
Carbon fiber has mechanical properties similar to those of steel, but is much lighter. Some carbon booms are designed to allow the mainsail to be rolled inside them.
The size of the boat and its mainsail are the primary criteria for choosing a carbon boom. The possibility of roller reefing also should be considered.
