Unifiber Carbon V2 Modular Boom - HD

HD carbon construction for more demanding sailing The Unifiber Carbon V2 Modular - HD is designed for windsurfers who want noticeably higher stiffness and more direct sail feedback than an aluminium boom can provide, without moving to the lighter and more expensive Elite construction. The boom body uses a 70% pre-preg carbon lay-up. The reinforced HD construction provides a strong balance of stiffness, durability and value. Reduced flex under load gives a more stable feel in gusts and more direct power transfer between rider and sail. Monocoque construction and reinforced tube walls All versions use a Monocoque Boom Body with a continuous arm structure. This improves load distribution and reduces unwanted movement through the front section of the boom. Tube wall thickness varies depending on size: 140-200, 160-220 and 170-220 cm - 2.2 mm 190-240 cm - 2.5 mm 220-270 cm - 2.8 mm The larger versions are therefore reinforced to handle the higher loads generated by bigger freerace and race sails. Ergonomic grip matched to boom size The boom arms use a slightly oval profile designed to sit naturally in the hand and provide a secure grip during longer sessions. Grip dimensions vary by size: 140-200 and 160-220 cm - 26 x 27 mm 170-220 cm - 27 x 29 mm 190-240 and 220-270 cm - 29 x 30 mm The smaller versions offer a slimmer hold, while the larger tube sections help maintain stiffness on longer booms under higher loads. High-density EVA around the front grip section improves abrasion resistance during regular use. Modular Boom Head This version is equipped with the Modular Boom Head, designed to provide a stiff and direct connection between boom and mast. The head allows axial movement, helping it align correctly with the boom position on the mast. RDM and SDM adapters are included, allowing the boom to fit both common mast diameters. The Modular Boom Head is a suitable choice for riders who prioritise connection stiffness and precise sail feedback. Inside Wide Tail - compact and direct handling The 140-200, 160-220 and 170-220 cm versions use an Inside Wide Tail, where the boom tail slides inside the boom body. The inner tail width is 15.5 cm. This provides enough clearance for modern sail profiles while maintaining a compact and direct feel. The IWT versions are particularly well suited to freeride, bump & jump and wave sailing. Outside Wide Tail - for larger sails The 190-240 and 220-270 cm versions use an Outside Wide Tail, where the boom tail slides over the outside of the boom body. This layout provides a favourable stiffness-to-weight ratio and helps reduce rear-end swing weight on larger boom sizes. The 190-240 cm version has a 17 cm inner tail width and is well suited to larger freeride and freerace sails. The 220-270 cm version uses a much wider 29 cm tail, providing the clearance required for deep-profile large freerace and race sails. Pulley system on every size Every Carbon V2 Modular - HD version features a pulley system at the clew. This allows smooth and precise outhaul adjustment. On larger setups, the pulley system can also be used with an adjustable outhaul, depending on the chosen configuration and hardware. Configure Me The boom is part of the Unifiber Configure Me modular system. The boom head, body and tail are separate compatible components. This makes it possible to replace a worn part without buying a complete boom, change to a different boom tail or adapt the setup over time.
