Boom Gaastra Green Line Mono

Thanks to its optimized length adjustment system, the Green Line is significantly stiffer than its counterparts on the market. The increased diameter(29mm) of the boom makes it more durable and efficient even in extremely strong winds. The Green Line boom collection includes 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 in the construction. By reducing the moving parts and making the boom from a single piece of aluminum, it is rigid and much stronger. The Green Line is characterized by its performance, durability and affordability, making it the ideal boom for both beginners and advanced windsurfers.
