All sizes of the GA Green Line are shaped in a different manner to get the best performance for your sail in each length. The longer the boom gets, the wider the bend is, giving your rig the perfect balance and enough space to make a deep, powerful profile work smoothly. With a double push-pin operating system strength and durability are guaranteed even in the roughest conditions. The finishing touch is given by the GA boom grip that adds ultimate and direct feeling for your rig.
