Terry did a beautiful Jet Boat Builders Christchurch Resource job on his boat and the modifications Jet Boat Builders Christchurch Online and we are so proud of him! This is the third Glen-L boat Terry Jet Boat Builders Christchurch Online has built and it sounds like he has plans to build another. I had an opportunity to meet Terry and see his boat at the Gathering which is where this video was filmed. Terry is such an enthusiastic person and Jet Boat Builders Christchurch Online a delight to know. Ahhh, so many boats, so little time! Glen-L boat builders are the best people! Thanks Terry for letting us take this video of Jet Boat Builders Christchurch Online you.
For those of you watching the video, be sure and post a comment below�. Chris is so good and has become a regular at our boat Jet Boat Builders Christchurch Online builder Gatherings. He is very good at asking good questions and taking the initiative with what he films. Glen-L marine designs has been serving the amateur boat Jet Boat Builders Christchurch Online builder since and the business resides in beautiful San Clemente, California.

Distinct styles, potent power, and a capacity for five put this jet boat Bred to break industry standards on fun, the Scarab was born to quench a thirst for adrenaline.
Swift and agile, it carves out the turns then f Catch a glimpse of greatness: where mastery meets dominance stands the Scarab Bold and beautiful, devoted to onboard comfort, and easily churn A lack of power supply hindered further development and after World War II, Hamilton opened an engineering business in Christchurch. He helped Jet Boat Builders Christchurch Online design and build the first rope ski tow in New Zealand, and in Builders Christchurch Online Jet Boat at the age of 52, he revisited his boyhood idea of creating a Jet Boat Builders Christchurch Online boat that could travel upriver with ease and would be able to navigate the shallow waters around his Station.
Bill Hamilton at the drawing board, Irishman Creek ca. In , after experimenting with a number of concepts without great success, Hamilton approached Christchurch boat-builder Arnold France to advise on the design. France suggested a jet unit and loaned Hamilton a US pamphlet on the Hanley Hydro Jet which used a centrifugal water pump system.
Throwing water out backwards creates an opposite reaction that drives the boat forward. Hamilton replicated the system Jet Boat Builders Christchurch Worldlink and put it into his Jet Boat Builders Christchurch Online first jet boat, a 3. Water was drawn in under the hull and expelled out a leg in the bottom of the boat. Despite his best efforts, however, the boat was only capable of an unspectacular 17kph barely faster than a river current. In addition to this, because the leg extended below the hull it was prone to damage in the shallow rivers.
So Hamilton and his team reworked the original design to expel the jetstream out the transom stern of the boat above the water line, a modification that saw the top speed jump to 27kph.
The design eliminated protrusions below the hull exposed to damage. Conjecture Jet Boat Builders ChristchuJet Boat Builders Christchurch Online Jet Boat Builders Christchurch Online rch Online posits that the idea came from a high-pressure fire hose in Kiwiana myth this has become a high pressure milking hose. Whatever, it was the genesis of the modern waterjet propulsion system.
Hamilton sold his first boat in to a friend. A further breakthrough came in when George Davison, a Canterbury University Engineering graduate working with Hamilton, suggested a 2-stage axial-flow unit.
Others had tried using an axial-flow device for propulsion rather than a radial pump or the traditional screw propeller , but Hamilton succeeded in finding a suitable application, where its advantages shallow Jet Boat Builders Christchurch Online draught and high manoeuvrability outweighed its disadvantages lower efficiency and higher expense compared to Jet Boat Builders Christchurch Online standard propeller power.
Bill on the Ohau River � Easter Shifting to the axial flow jet which generally means high volume and low velocity meant Hamilton could Jet Boat Builders Christchurch Online Jet Boat Builders Christchurch Online pump a greater amount of water than with the centrifugal pump low volume, Jet Boat Builders Christchurch Online high velocity. To increase the velocity of the water, and thus increase boat speed, they incorporated a series of impellers and stator veins which straighten out water flow behind each impeller and added a narrowing of the outlet nozzle.
The result was that the waterjet unit could now pump a high volume of water Jet Boat Builders Christchurch Online and expel it at very high speed � meaning it could now be used successfully on bigger and heavier high-speed vessels. After further modifications and the addition of a 3-stage unit, the jet was able to reach speeds of up to 80kph.
Steering was controlled by swivelling the outward flow. Hamilton finally had the Jet Boat Builders Christchurch Online craft he dreamed of: a boat able to swiftly manoeuvre past jutting rocks, Jet Boat Builders Christchurch Online Jet Boat Builders Christchurch Online and forge upstream through malevolent currents. Because there were no protrusions below the hull, the boat could operate in only centimeters of water, perfect for the stony, braided, southern riverbeds. In the go-against-the-flow innovation of the Hamilton Jet proved itself when Jet Boat Builders Christchurch Online it became the first vessel a boat called Kiwi to travel up a km section of the Colorado River that flowed through the Grand Canyon.
Bill Jet Boat Builders Christchurch Online had broken his arm in a boating accident, so his son Jon was at Jet Boat Builders Christchurch Online the helm. It was a nine day current-bashing marathon that saw the Hamilton Jet negotiate all obstacles, including the mighty Vulcan Rapid. Four boats made it up Jet Boat Builders Christchurch Online the Colorado River in , all powered by Hamilton waterjets. After this spectacular demonstration other rivers were successfully navigated and the invention was embraced across the planet. The uses of the jetboat were manifold: fishing, oceanic research, tourist travel, fire-fighting, taking Jet Boat Builders Christchurch Online geologists into the hinterland of New Guinea or scientists and missionaries up the Amazon, Jet Boat Builders Christchurch Online Jet Boat Builders Christchurch Online supplying remote Pacific Islands or aiding food relief in India.
His modest explanation for how he did it? By keeping an open mind. World-wide demand for Jet Boat Builders Christchurch Online the jets steadily increased throughout the s and s to the point that manufacturers Jet Boat Builders Christchurch Online in the US, Canada and Britain were contracted to produce Hamilton waterjets under license. The economic conditions of the late s and early s led the company Jet Boat Builders Christchurch Online Jet Boat Builders Christchurch Online to phase out its general engineering business in order to concentrate solely on Jet Boat Builders Christchurch Online the more profitable production of waterjet units for export.
Hamilton Jet became the main division of the company with the mandate of building a wider global distribution network for the jets. As this strategy began to prove successful, factory capacity and staff levels were expanded considerably to meet the growing demand. An estimated 35, jet units have been produced by the factory, and since the s, over boats.
