Boom Gaastra Black Line Mono

Thanks to its optimized length adjustment system, the Black Line is significantly stiffer than its counterparts on the market. The diameter of the boom has been reduced to 27mm at strategic points to ensure a firm grip and to facilitate steering in extreme conditions. The latest collection is available in 4 sizes, each with a unique shape ideally suited to each surfer's needs. Gaastra booms are made using Monocoque technology, which uses a single aluminum tube. By reducing the number of moving parts and making the boom from a single piece of aluminum, the designers have made it stiffer and much more durable. The Black Line is characterized by its performance, durability and affordability, making it the ideal boom for both beginners and advanced windsurfers.
