The 2020-21 DUX, HammerHead / PD-400

The Hull Difference Between a Traditional Inflatable Boat and the “DUX” Catamaran and Tunnel Hull is like the Difference from Night and Day.

What do we mean when we say “The HammerHead, PD-400 model is a Twin Sponson designed, True Tunnel hull inflatable boat?” Although the dimensions and physics involved in building such a hi-performance boat are kept as intellectual property, it is proven the Tunnel Hull is calculated, created, and added to the bottom of this boat in a very strong manner!  This tunnel allows the air to run under the floor and above the water of the Dux Tunnel hull boat line. 

i.e. models beginning with PD (Performance Dux) or SRD (Search & Rescue DUX are True Tunnel Hull Designed Boats.

With the years of testing and additional years of actual ALL WATER and ICE CONDITION including Dam head and hurricane rescues and flooded streets, the Tunnel Hull is a boat for many water conditions and for fun.

IMPORTANT NOTE: The HammerHead and other “PD” models, will operate in shallow water conditions as low as 6 inches on plane and 10 inches off plane.
