HULL MATERIAL
Polytecâ„¢
The GTR-X RS 300 features a robust Polytecâ„¢ hull material, which reduces the watercraft’s weight while enhancing its durability and scratch resistance. This innovative material contributes to the PWC’s agility and ease of handling, ensuring a confident and enjoyable ride for users of all skill levels.
Equipped with the Intelligent Brake and Reverse (iBR) system, the GTR-X RS 300 offers superior manoeuvrability and control. Recognised by the U.S. Coast Guard for improving boat safety, this system allows riders to engage forward, neutral, and reverse with ease, facilitating stable and worry-free low-speed manoeuvres.
The spacious swim platform provides enhanced stability and comfort, making it an ideal spot for lounging or preparing for water sports. With the inclusion of LinQ attachment points, riders can easily customise their watercraft with additional accessories, such as fuel caddies or coolers, to extend their adventures on the water.
