These are some of the highest quality masts in the world, made in Europe out of the best quality pre-preg carbon available. Due to their unique construction process, they offer a very high reflex response! These masts are what Aerotech sails are designed around, and all have a constant curve in their bends – which means they compliment all Aerotech model sails as well as many other brands that design around a constant curve perfectly! The lower section on the SDM Race and Free Race masts have a texillium finish, which protects against abuse and sun exposure for a longer lifetime.
