Summary of Investment opportunity to develop Treddlecat and incorporated marine propulsion system on Rarotonga.

1. The Treddlecat is a test bed for a new marine propulsion system.

2. Four highly successful models have been hand made by the designer two of which are in regular hire on Muri Lagoon getting rave reviews from visitors who use them.

3. The propulsion system appears to be more efficient yet much simpler to make and maintain than any other made to date. It has been patented in NZ.

4. To enable the development of the system for solar and steam power in larger vessels we need an outside investor to set up production of the leisure version on Rarotonga. This will generate an income by hiring the first few models here and by selling the next in NZ.

5. The initial marketing would be looked after by word of mouth from the visitors who have enjoyed their sorties on the ones here.

The investor would be encouraged to: -

1. Extend the patent.

2. Inject sufficient capital to get production going using Fletcher Melvin’s facility to make the hulls and Ken Kingsbury’s resources to manufacture the propulsion units.

3. Take on the tasks of general manager, marketing and accounting.

4. Ken Kingsbury would be more than happy to continue to develop the whole concept with the aid and advice of any specialists the investor chooses to bring in.

5. Ken has the assurance of Bob Riley, solar power consultant, that he will be on hand to develop the next stage.

Important note: -

The KSFDS (Kingsbury Swinging Foil Drive System) can be powered through a single ram hydraulic link from a simple linear motor (electric) or a simple single piston steam engine with no requirement for any rotating parts.

Recommendation: -

Any potential investor should be encouraged to visit Raro to try for themself the leisure version of this breakthrough invention.

The Treddlecat story; sixty years in the making.

Ken Kingsbury taxed the patience of parents and teachers alike with his questions from an early age.
“How does that sailboat go that way when the wind is going the other?”-was one that marked a critical stage in the development of his fascination with boats.
Although he ended up flying helicopters as a means of financing his marriage and family, getting afloat was his favourite recreation.
Right from the start the limitations of the various craft he took command of irked him. It always seemed to Ken that most of these limitations were inadvertently built in by the designers and manufacturers. In his mind he automatically worked out ways of pushing back these limitations. He soon realised there was always a way of doing this by modification of the original design.

In this way he learnt a wide range of first principles of mechanics and dynamics and could apply them to almost anything that caught his interest.
Much later in life Ken realised that evolution has mindlessly found the most efficient way of converting energy to forward motion through aeons of trial and error. He was amazed that intelligent men seemed to consistently ignore the conclusions of Natures millions of years of research in the pursuit of survival.

Half a century of modifying and redesigning boats and windsurfers as a hobby eventually led him to tackle the problem of propelling boats with human muscle.
The catalyst for this was being asked to make a “pedallo”for hire at a resort on a coral lagoon.
While examining on of these ridiculously inefficient man-powered boats a number of ideas of improvement jumped into his mind. Memories of being towed around in a boat by a large fish on the end of a line made him realise the superiority of the fish’s propulsion system.

His preparation started with the establishing two first principles.
1.The higher the proportion of available energy being used to disturb the water the less is left to move the boat forward.
2.Water being a liquid, the less time it is given to move in response to the driving force applied to it the less the energy wastage.
After studying fish in motion he arrived at this conclusion; the fish moves its fins in such a way as to make them track forward through the water taking the fish’s body with them.
The concept of the “Kingsbury Swinging Foil Drive System” took shape.
Although the first trial of the first version of KSFDS exposed a number of mechanical miscalculations it showed potential.
Over the next year the system was extensively modified until it appeared in a small catamaran called the “Cruzicat”. Using the leg muscles of two persons sitting in the hulls this vessel could sustain 8 kph with the energy needed for a brisk walk.
Hiring it out on Muri Lagoon soon uncovered its weaknesses. After a few years of repairing and modifying the Cruzicat, during which time a second improved design was introduced. Because both had mechanical linkages from the pedals to the swinging foils the vessel was doomed to be repeatedly damaged due to the foils being unable to swing back on encountering obstructions.

The radical change in design that produced the Treddlecat seemed in retrospect an obvious solution. In solving many problems it resulted in improved efficiency, simpler construction and dramatically improved resistance to damage.
Ken’s predictions were uncharacteristically pessimistic in picking 5 knots for the top speed of the Treddlecat. The Mk I prototype reached 5.4 and the Mk III, 5.7. with Kens arthritic knees doing half of the work.
He is currently working on a Mk IV which is intended to demonstrate the efficiency of the system by beating the local racing canoes.
Although quantitative analyses has yet to prove it the KSFDS seems likely to be the most efficient man-made marine propulsion system.

From your point of view as the user of the treddlecat for leisure the most important feature is its ease and comfort and the fact that you can virtually do no wrong.

The Treddlecat Advantage.

When the Treddlecat enters the world market it will offer ordinary people a level of enjoyment above that of any other watercraft.

People without any boating skills will experience a ride that is swift, smooth and silent.

The two persons providing the motive power will find they can hold a conversation without raising their voices or twisting their necks.

They can carry an equal number of passengers in comfortable forward facing seats with sheltered stowage for cameras and the like.

The only navigating consideration needed will be the steering via a light touch joystick in front of one of the pedalling seats.

The stability will make for easy climbing on board after snorkelling or swimming.

The hands free operation makes fishing, photography or picnicking when under way a natural activity.

All occupants of the Treddlecat’s seats can safely change places while afloat.

No athletic prowess is required to propel the Treddlecat against a 7kph current or a 20-kph wind.
