XTREME
HIGH PERFORMANCE TUNNEL HULL INFLATABLES
TUNNEL HULL INFLATABLES ORIGINATED IN SOUTH AFRICA WHERE THESE CATAMARAN DESIGN CRAFT ARE WIDELY USED IN SURF RESCUE  
COMPETITION RACING AND AS GENERAL LEISURE BOATS. IN RECENT YEARS, THE POPULARITY OF TUNNEL HULL INFLATABLES HAVE
SPREAD TO OTHER REGIONS WORLDWIDE INCLUDING EUROPE,  AUSTRALIA,  NEW ZEALAND,  AND  NORTH AMERICA.  
The Xtreme  tunnel-hull Cat design  creates a mixture  of aero
and hydrodynamic forces which causes an almost flying  effect
at  full speeds. The tunnel hull  helps  to stabilize  the  boat
when  running in rough water, and  to maintain a level angle
attack even when it is airborne. The XTM enters and exits  the
water on a level plane and when  returning to  the  water,  the  
tunnel  hull   compresses  the   air  underneath, thereby,  
softening  the landing.  The hull is based upon exact planing  
surfaces  to minimize wetted  areas  and  further reduce  water
resistance  by causing  air bubbles  and turbulence, providing a
faster surface for the XTM to run on.
The new XTM Xtreme  is built on the top performing MAKO racing Cat, a
proven design refined after years of racing competition.
