The BONDED.TECHNOLOGY is a unique NORTH SAILS production technique that uses space-technology adhesives to glue the tubes to the head. As a result, the SILVER boom is as strong and rigid as one-piece booms (that cannot be disassembled), and the weight remains very low. Propulsion forces are directly transferred without any play through the PRO.GRESSION III front piece and the continuous rear. All SILVER models feature the oval SQUASH.GRIP for greater comfort and RDM tubes with varying diameter depending on the length: 28 mm for lengths from 1.40 m to 1.60 m, and 30 mm for greater lengths to ensure maximum rigidity even for the long SILVER models. Five boom lengths with refined specific bend curves are available, making SILVER booms perfectly suitable for all sails from Wave to Freerace.
