Sports Utility River Boat UD-400X

Sports Utility River Boat UD-400X

These models of DUX Inflatable boats, are similar to the River Universal DUX, model D-400.  The only difference is as little as it seams, is a Fiberglass planning pad, form fitted to the bottom of the Sponson, and then filled with a 2 part Marine Flotation foam.  We call these, DUX FEET.  As simple as this sounds the amount of Labor and materials make up the price difference.  In return you will get a DUX Boat that can do all that the River or fishing model can, but in addition it will plain better, turn like a HammerHead, and is capable of pulling tubers or makes a great Kite Surfing Boat.  A great swim team, chase boat and all for a lot less than the Performance models found in this site.
