Elite carbon booms are custom manufactured from the highest grade pre-preg carbon. These designs are targeted at the professional user searching for the greatest stiffness and lightest weight.Short 140 model has the thinnest grip diameter in the range and a narrow profile to better suit compact sail profiles found in Bump & Jump and Wave sails.Sizes 190 and 220 are fitted with larger diameter outside tails that minimizes the back-end swing weight and keep the rig under better control.
