The Chinook Sailing Reduced Diameter Grip (RDG) Alloy Boom is 2mm smaller than our standard Pro-1 Alloy booms. Featuring absolute length markings, the strong 60cm tailpiece is easily rigged to your sail. A rounded front curve makes hand transitions during jibes, tacks, and the most advanced freestyle moves feel natural. Exceptional torsional rigidity and fits both standard and reduced diameter masts perfectly.
