With many knockoff’s now emerging, and entering the race coarse, it is imperative that the engineering of these outstanding watercraft stay 2 years at minimum ahead of the competition. This is done through constant R&D, testing and a religious life style to the sport. Hydrodynamics and Aerodynamics are a key if understood correctly. There are literally thousands of physics laws, and each serves a purpose. These laws are not to be left to those that are in this business for money! You must care about the safety of the end user!  That is the DUX top priority.
