The PowerSki JetBoard
We received an email about the new model of the Powerski Jetboard two weeks ago and thought that some of you might be interested.
The
following is from their web site.
Wave
Riding
Although the PowerSki Jetboard™ allows surfing on any flat body of water,
those that take it into the surf will find the future is here. It is the commitment
of Powerski International not to promote the "takeover" of surf spots
but search out the out of the way breaks and the big tow in only surf breaks.

PSI's patented two-stroke, water-cooled engine built for the Jetboard puts out 45 HP. The dimensions of this revolutionary new engine design is 6.5 -inch tall by 10 -inch wide by 17 -inch long. This 330cc engine currently weighs over 40 pounds, but use of a metal matrix composite material will drop the weight to approximate. 38 lbs. The entire craft was engineered with Parametric Technology Corporation on HP Workstations.
An axial flow jet pump delivers over 350 lbs. of thrust through a proprietary gear-reduction transmission. The gear reduction, built into the bottom end of the engine, is new to the power watercraft industry. It enables engineers to match the engine's optimum rpm to that of the jet pump to enhance the craft's performance.
The PowerSki Jetboard's design puts the center of gravity under the rider's feet, rather than behind or in front of the ride-as is the case with similar sports water craft. Dual hydrosteps on the bottom of the hull put the pivot point directly under the rider's feet, enabling high-speed planing and turning. The hydrosteps lift the craft partly out of the water as it skims along, and direct the line of water rushing past the rails during top speed turns, stabilizing the craft.
The modular handle assembly consists of the grip, start/stop buttons, independent left and right thumb throttles, speedometer, fuel gauges, and safety kill switch. Sub-assemblies are attached to a four-foot long arm-pole consisting of steel cable and a sleeved wire harness covered by injection molded rubber that provides structural strength.
The grip is removable and replaceable. Scientifically engineered finger grooves to prevent hand and wrist fatigue are coated in cushy soft, textured sanitex/ saniprene rubber and nylon laid over a thermoplastic elastomer surface.
There were five significant natural forces the engineering team had to deal with; weight, buoyancy, hydrodynamic lift, drag, and thrust. The Igniter 2000 combines a high thrust to weight ratio with a hull/rail design and center of gravity placement that stabilizes the craft at all speeds. The design also enables high-speed planing and high thrust "G-Force" turns with simple shifts in weight of a rear-mount.

The Outrider Flying Boat
We came across this invention earlier this year and thought it worthwhile having another look. The following is from their web site.

Safety makes OutRider unique. To our knowledge it is the first boat that is aerodynamically stable in and out of ground effect. Unlike a conventional boat that relies only on whatever small part of its hull happens to be in contact with the water, OutRider utilizes every square foot of its surface to provide stability aerodynamically. It relies on the wind for both lift and stability. Because OutRider is completely immersed in the fluid that is its principle source of stability, it boasts handling that is both safe and predictable.
To assure that safety is not a matter of guesswork, Klem Flying Boats conducted over 1000 tests in the Georgia Tech Research Institute’s wind tunnel. Virtually every test was supervised personally by Dick Klem utilizing an exact scale model of OutRider machined from a solid block by a computer controlled (CNC) milling machine.
The extensive testing enabled us to verify OutRider's aerodynamic stability at any altitude. In fact, we were so encouraged by OutRider’s ability to achieve a steady glide totally "hands off", we are exploring a military version that can be dropped from an airplane with no parachute and flown safely to a smooth landing on the water.
OutRider features familiar boat controls: steering wheel, throttle, and trim. The steering wheel operates the water rudder and the elevons, which control body roll and are similar to the elevons found on jet fighters. Because high speed turns are initiated aerodynamically they can be taken safely at top speeds.
OutRider is comfortable, because its hull flies over most waves. Water contact is mainly at the ski and the bottoms of the tip plates which are only an inch and a half wide. Because these areas are small and the ski has a spring/shock absorber, the ride is very controlled, isolating occupants from harsh slamming found in other high-speed, small boats.
In addition, the windshield, headrest, and cockpit sides are wind-tunnel shaped to create a "bubble" of relatively calm air for the pilot and passengers. And, OutRider is quiet enough to avoid stressing passengers and other friends on the water.

2003 Magoo Charity Classic (held on the Central Coast of NSW, Australia)
Each year Gumby Lock sponsors the Magoo Charity Classic and we were very pleased that this year's event was better than ever. Here is James Purcell's report.
The
2003 Magoo Charity Classic was a HUGE success raising a record
$37,000.00 for cancer care
and cancer research.
Over 140 surfers contested the 11 divisions in classic 3-4 foot
Norah Head left handers (Magoo's home break - directly below
his house), with great waves and a great time had by all.
Special
thanks to all of our valued sponsors who enabled us to raise
$11,000.00 at the charity auction and $2,500.00 in the
charity raffle. Combined with a huge $17,000.00 from the
head shaves ($15,000.00 for yours truly), and the contest
entry
fees and food tent revenue, the new record total was achieved.
Once again, thank you so much for your generous support of
this great event. It is greatly appreciated.
We hope to get your continued support for the 2003 Central
Coast Longboard Open in November, and at next year's Magoo
Charity
Classic.
Kind Regards,
James Purcell
(For and on behalf of Central Coast Malibu Board riders Club Inc.)
We have posted the contest results are on the Central Coast Malibu Board riders Club web page.

THE ROARING FORTIES by Roger Smith, surf guide with www.dawnpatrol.co.za
Why do I live in East London, main centre of the "Border" region of South Africa?
We earn less than those who live in larger centres, and more affluent areas of the country. We don't have the facilities that are available in other areas. But we have waves!
The main source of our swell is "the Roaring Forties" - massive cold fronts that rumble past thousands of kilometres to the south in a continuous belt of low pressure systems. They never stop. The gigantic swells generated by these systems push steady lines of huge swell before them.
Some of this swell bends off to the north east and the north to arrive on our shores. Some of it presses on to cover massive distances and arrive at places like Indonesia!
The local result? A surf zone blessed with consistent ride able swell the whole year round. A mild climate with a prevailing offshore wind that provides us with all that we need - points and bays, reefs and beach breaks, lefts and rights.
Here are some recent photos of the waves in the East London area.

Louis and Roger run Dawn Patrol, a surf tour operator based in East London on South Africa's south east coast. They and their support team move up and down the coast, surfing the best waves on offer between Jeffrey's Bay and the Kwa Zulu Natal South Coast.
