The new Racing Design for the 2001 / 2002 Season

As a result of eight years of development in stringent racing conditions, the X-Treme surpasses any other craft in strength, durability, and handling.

The X-Treme Racer has a unique tunnel hull design created from a mixture of aero and hydrodynamics which causes a phenomenal, almost flying effect at full speeds. The craft is stable and responsive at speeds of up to 100 kilometers per hour. The tunnel helps to stabilise the boat when running in rough water, and to maintain a level angle of attack even when the boat is airborne. The X-Treme enters and exits the water on a level plane and when returning to the water, the tunnel compresses the air underneath, thereby softening the landing.

The X-Treme uses a combination of high tech products to establish exact planing surfaces. The design on each planing surface minimises wetted areas planing resistance by causing turbulence, which produces air bubbles under the planing area, providing a faster surface for the X-Treme to run on. Built into the planing surface is a spray rail, which deflects water downward to enhance lift speed and fuel economy. The complete planing surface has proven angles to enhance stability in both tracking and turning.

X-Treme Test Results on Flat Water:

Motor Used - Yamaha 50HP Blue Print (D Model)

Test 1
Motor flat on transom, 15" Quicksilver bunny prop
109km/h

Test 2
Motor flat on transom, 16" Semi-Cleaver prop
110km/h

Test 3
Motor raised 16mm off transom, 18" Cleaver prop
116km/h

The fastest speed recorded by the same team with an oppositions boat is 103km/h with a 158" Quicksilver bunny prop.

SPECIFICATIONS

WHAT DRIVES THE X-TREME:

• You receive a softer ride in choppy waters and the prop doesn't leave the water often
• Wider hi-jackers soften the ride and reduce bouncing
• The narrower nose-cone ensures that the boat isn't flighty in surf and strong wind
• The tube and hi-jacker shape provides more stability and speed
• With the planing surface 15cm wider the boat runs more on the surface thus increasing speed

 ADVANTAGES

The advantages of the new X-Treme over our previous models are as follows:

Increase in speed both downwind and into the wind Much more stability Jumps flatter in the waves Very stable into strong headwinds or at high speeds Quicker off the mark (pull away) and quicker onto a plane coming off a jump Motor keeps its revs through surf, chop and downwind Turns very responsively and doesn't lose revs into or out of turns Runs very well in rough water conditions Less tiring to ride Softer on pilot and co-pilot Strength of nose-cone increased (Choice of design) Less boat flexibility due to design
