V-Grip for comfortable longer sessions
The Unifiber HD Alloy V-Grip Boom - Ergo Head features a distinctive V-shaped tube profile designed to follow the natural position of the fingers and palm. This allows a more relaxed hold and can help reduce forearm strain during longer sessions.
The grip measures 26 x 33 mm. Its slim 26 mm dimension makes the boom easier to hold, while the V-shaped profile adds structural integrity and provides more direct feedback from the sail.
This combination is aimed primarily at freeride and freerace sailors who spend long periods in the harness and value both comfort and precise sail control.
The V-Grip feels noticeably different from a conventional round boom, so whether it suits your preferred hand position will ultimately depend on personal preference.
Reinforced HD T8 aluminium construction
The boom body is made from T8 aluminium with 1.7 mm tube walls. The increased wall thickness of the HD construction provides greater stiffness and durability compared with standard aluminium booms.
The arm geometry is designed to minimise deflection under load. Combined with the V-Grip profile, this results in a rigid construction and more direct power transfer between the rider and sail.
The additional material also makes HD models heavier than Essentials Alloy booms, but the trade-off is increased stiffness and durability for more demanding sailing.
Ergo Boom Head
The boom is equipped with the Ergo Boom Head and its classic single-hinge lever. The system is straightforward to operate and allows the boom to be attached to the mast quickly.
The boom head provides axial movement, helping it align correctly with the boom position on the mast. RDM and SDM adapters are included, allowing correct fitting to both common mast diameters.
Two sizes for different sail ranges
The 140-190 cm version has a maximum inner body width of 38 cm and a 12 cm inner tail width. Its body uses a C-shape profile and the tail features the Loop & Go system for quick and simple outhaul attachment.
This size is particularly suitable for smaller and medium-sized freeride and freerace sails.
The 200-250 cm version is designed for larger sails with deeper profiles. Its maximum inner body width increases to 49 cm, while the inner tail width is 18 cm. The extra clearance helps prevent the boom from interfering with the sail profile and allows larger sails to maintain their intended shape.
The 200-250 cm version uses a pulley tail system, making it easier to apply and fine-tune outhaul tension when dealing with the higher loads generated by larger freeride and freerace sails.
Stable length adjustment
Both versions use Double Pin Locks mounted on the boom body. The two pins securely lock the tail at the selected length and help minimise unwanted movement under load.
The tail tube diameter is 22.5 mm on both sizes.
Durable finish
High-density EVA is used around the front grip section to improve abrasion resistance in areas exposed to frequent wear.
The anodised tail improves corrosion resistance and long-term durability, particularly for riders who regularly sail in salt water.
Inlaid & Embossed grip graphics are integrated into the grip surface rather than relying only on a conventional surface print, improving resistance to wear.
