The DUX RD-400XL has many great features, including more floor space, maximum stability, unmatched speeds, and superior handling capabilities in rough waters.

With many knockoffs now emerging and entering the racing circuit, it is imperative that the engineering of the RD-400XL stays, at minimum, 2 years ahead of the competition. This is achieved through constant R&D, testing, and an unwavering dedication to the sport. Hydrodynamics and aerodynamics play integral roles in racing and the DUX RD-400XL is designed with these concepts in mind. In fact, there are countless physics laws that serve a purpose in boat racing, and each one must be taken into consideration when designing a world-class racing boat. This helps ensure the safety of the end user, and that is the DUX top priority.
