DIYNO 951 Jet custom kit built by Caird Marine Launched

Alex Caird of Caird Marine in Te Anau launched the Jim Pauling Designed 951 Jet. The kit was supplied to Caird Marine through DIYNO Kitset Boats. The boat did 36 knots on launch day. A full 7 knots faster than the Hamilton Jet speed estimate which just shows how efficient the hull is. The boat has been meticulously built and met its target weight of 3.5 tonne fully fueled on the trailer making her completely road legal in New Zealand.. The boat was bult on one of my alloy jig/trailers where the jig becomes the trailer. They are light and strong and hull matched to the boat making towing easy. First fish pulled aboard was a Tuna out of Milford Sound. Stunning Boat and congratulations to Alex.

Remedy 31 tourism powercat launched in Fiji

Sea trials have been done for my Remedy 31 Powercat. Designed for tourism charter operations in Fiji, the boat is unique in that it operates efficiently in displacement mode when fully laden but can kick up its heels and plane in light ship mode which enables it to get past the limitations of full displacement hull types. Top speed on the first sea trial was 31.7 knots which exceeded my own performance estimate.
Some feedback from the owners/operators of the boat, "We love the boat, it is the best dive boat we have ever had"
Video of the sea trials can be viewed at this link

Jim Pauling Yacht Design WAP 1302 Powercat launched in Fiji

My 1302 WASP powercat was launched in Fiji recently.

Designed to carry 45 passengers she has two large heads and a forward bow ramp to make getting on and off the boat very easy for passengers at shallow beaches.
She draws very little water so the boat can get very close to shore when disembarking passengers through the forward bow ramp/stairs
She also has a side door each side aft for disembarking alongside piers and a stern platform with ladder.

Powered by four 300Hp Suzuki outboards she reached 38.4 knots.
The video shows how she quickly gets to planing speed without excessive trim and holds it there simply lifting as the speed increases.
There are no foils on this boat.
You can see in the video as the boat approaches and passes close to the camera how little wake is generated by the hull.

Yacht Chaser

Built By Silver Fern Creations, USA

This beautiful boat is being built by Andrew Berge from Silver Fern Creations in Michigan USA. Designed to follow the clients son around the yacht racing course without impacting on the race. It has low wash and very efficient hull characteristics. Designed to operate for long periods at slow speed but with the ability to race to the top mark at 20 knots when needed in all conditions as the yachts often race in rough seas.
What a stunningly beautiful build. The boat came in on weight and some of the detailing is stunning. Just so beautiful to look at. And so graceful operating on the water to match the look as can be seen in the videos below.
I incorporated into this design some new ideas for enabling the boat to operate efficiently at all speeds. The results can be seen in the video, particularly the one of the boat running so effortlessly at 13-15 knots. This is usually a very difficult range for a planing boat but as can be seen this boat is capable in displacement, semi-displacement and fully planing mode.
It will be good taking this new design into a 40-50 foot size boat. What a boat that would be. Even a smaller 30 foot boat would be sensational. Others say all boats are a compromise. This design shows it is not necessarily so. To view on Rumble click the link below https://rumble.com/vnj2qy-first-sea-trial-of-the-jim-pauling-yacht-design-yacht-chaser.html

Incredibly the boat is doing 13-15 knots in this video. One of the criteria for the design is it could operate well at any speed. It looks effortless and comfortable at this speed. I had to ask the question 3 times to confirm with the owner that it was in fact sitting at that speed. Compare that to most other 6 metre boats at that speed. It is not a speed that most boats are comfortable to operate at. And look at the wake. There is hardly any which was a requirement of the design also. Minimal wash so as not to affect the boats racing.

Cruising at 20 knots. Top speed is 23.5 knots allowing her to quickly get ahead of the fleet when needed or to support a boat in trouble. The hull is soft riding and comfortable at any speed up to her maximum in all conditions. And once again note how little wake is coming off the hull.

WASP 825 powercat launched

The 825 WASP powercat was recently launched for whale watching in Tonga. The boat features side doors and rear access to the water to get the passengers into the water quickly to interact with the whales. Here is what the owner said about the boat after initial trials.
The boat handled the conditions extremely well. My
skipper, who has been driving whale watching boats for 15 years, was
very impressed.
The stability in rough water is much better than he has ever had before and
the ride was very smooth in his opinion.
The pick up and the top end speed were good.
I think the boat will be a great success.
I will be heading out soon to do tests in rougher water but in the harbour here, we had just over 30knts at 5400 rpm.
I’m sure the boat will be completely fit for purpose, it’s had a lot of attention from other whale watch operators and it looks great.
Kind Regards

Rêvo Boxta 45

Rêvo Boxta 45.
4-5 seat Non Reinforced Plastic (NRP) jet boat.
The big strong silent type.
Commissioned by an owner of the smaller Boxta who said "the boat is so good I don't want to boat in anything else now". But he did want to be able to take family and friends aboard so commissioned the Boxta 45.
Here is what the owner Bill Winmill said about the boat:-
The boat is so smooth and quiet and handles rough water so gently without banging.
Performance and handling are superb. So responsive.
She planes so quickly and at such a low speed. Coming down river is very safe. You have so much control.
She just goes where you point her. Handling is superb.
Can't believe how easy it was to get the boat back to water. It slid very easily unlike an alloy boat. But what amazed me most was how it required so little water to get it planing. It hrdly needs any more water than it takes to float the hull to get it planing and it floats in less than 300mm of water. About a half to one third of other boats this size.
It is one tough boat. We ran it 40 metres high and dry. No damage at all. We have had some massive hits fully loaded at speed and not compromised the hull. She is one tough boat
The boat is so easy to work on for maintenance. The full engine bay and cover is brilliant. There is so much open space all around the engine and jet so getting access to all parts is very easy. And it provides good storage space for gear when on a weekend camp.
I couldn't be any happier. She is perfect.

Fully fabricated Polyethylene hull professionally designed/engineered and professionally built using new technology for an even better stronger boat and more dimensionally accurate accurate hull shape.
Chevy L86 alloy V8
Scott 852 water jet.
This unit is fitted with a trim nozzle but the owner does not use it. He does not need to alter the trim at any speed. It is all set by the superior design which increases efficiency and improves handling making the boat faster and safer. Using trim to alter trim angles is wasting horsepower and ultimately will not make the boat safe. The ride angles must be set by the design for safe efficient handling. No chine walking at speed in this boat!
125 Km/Hr top speed.

The final part of the design process is validation. Checking how the boat performs compared to the design predictions. This is more than just speed it includes ride angle and ride heights. This verifies my formulas are correct so is a vital part of the design process. The video here is part of that evaluation process.

24 metre Superyacht - 'Amnesia'

Jim Pauling's biggst design commission to date.

Jim Pauling Yacht Design was responsible for Naval Architecture for this vessel. I had the pleasure of going aboard and meeting the owner, whilst on a trip to Thailand recently where the boat was built. An amazing man and an amazing vessel. An extremely well thought out/laid out boat. Styling done by her owner.

Some preliminary sketches of a development of this hull set up for jet drive and a tripple deck superstructure layout.
She features 6 double cabins including a huge master cabin plus a movie lounge are. A practical superyacht with good access for all maintenance and sensible operation. She is a boaters boat with plenty of room, great performance and an affordable price tag.

Rêvo 601 Superfly

The Rêvo 601 Superfly is a six metre welded polyethylene longboat.

This is the first welded polyethylene boat in survey in New Zealand and while it has been a testing process the results have been well worth it.

Purpose designed for salt water fly fishing charters, the boat is a development of our original polyethylene longboat hull form. The boat is capable of operating at any speed up to its maximum of 30 knots with a 60 horsepower motor.

We also offer this hull with jet drive and a 40 horsepower tiller steer outboard option.

This 16 metre Barge was built by Stephen Sneddon at Weld NZ.
It was amazing how they turned this project around in the timeframe available as the digger and barge had to be on the ship by a set date as ships apparently do not deliver to Pitcairn Island frequently.

My contribution included the design and submitting drawings for survey, structural calculations including the design of the bow ramp and hinge detail, lifting points for lifting the barge over the side of the ship at sea, stability calculations and providing cut files for the manufacture of the design. The barge was specifically designed to take the 24 tonne digger ashore at Pitcairn Island as shown in the pictures. All the design work and structural calculations plus stability calculations were based around this event. Barges are not my usual line of work but seeing the results of this project are very satisfying and I did enjoy the project and would happily do it again.

Rêvo 651 Sportfly

JPYD designed, Rêvolution Yachts built, Rêvo 651 Sportfly, NRP sport/fly fishing boat for an Auckland customer who fished aboard the 601 Superfly and loved the boat but wanted something slightly bigger for fishing and diving as far afield as Great Barrier. The boat was custom designed and built for his needs, including beach launching and able to be handled by one man. Set up for salt water fly fishing with two casting decks and a massive double skinned built-in fish bin, but also to be used for general sport fishing and diving.
Once again a very efficient and well mannered boat able to operate at any speed.

6.5 metres long with 90 horsepower motor - 31 knots.

The pictures and video show just how smooth and responsive the hull is. Virtually no transition from non-planing to planing mode makes the boat very responsive and able to operate at any speed. The most fuel efficient speed is 13 knots giving a 106 nautical mile range or 96 nautical miles at 18 knots.

Comments from the owner:-

She is just so responsive.

She is pretty much planing at any speed.

It is so quiet and smooth.

Comments from others who have been aboard:-

The ride is unreal. I have never been on a boat like it.

You will be impressed with this, it is so smooth and responsive.

JPYD specialise in commercial jet boats

I love designing jet boats. Jet boats expose any flaw in a design so to be successful they have to be designed perfectly. And a perfectly designed jet boat will be the best boat you ever own. A badly designed jet boat will be the worst boat you ever own. Below are some examples of our commercial jet boats. Very successful and loved by their owners. All these boats are blue water boats that work offshore. The boats all handle open water superbly and none require trim nozzles.

9 metre Rêvo Jet

9 metre Rêvo Jet coming home over the bar. This boat runs a 430 Yanmar Diesel coupled to a 274 Hamilton Jet. She operates out of South Westland over notorious and difficult bars.

5.5 metre Diesel Jet Workboat

This is a Rêvo 5.5 metre commercial jet boat designed for working offshore. It runs a marinised Toyota 1KZ diesel engine couple to a Scott 851 Jet. Designed for hauling nets it was designed for bollard pull rather than top speed but still does 32 knots.

MADAZZ Marine 3.6 metre Jet Boat

Built in Queenstown by MADAZZ Marine, this is one of my 3.6 metre jet boats. This was the first sea trial. The smile says it all really. His comment after the sea trial was "I just can't believe how well it handles"
None of my jet boats require trim nozzles which are so common these days to correct poor handling. The trim is set by the design. If a jet boat requires a trim nozzle, be very wary of it.
Note how easily the boat planes and at a very low speed without dropping its stern. This means the boat can operate at low speed in rivers but can accelerate effortlessly to full speed all the while drawing very little water. It also means that the boat requires very little horsepower to plane.
Enjoy a short video of the first sea trial here:-

Rêvo 821 Jet

Designed for fishing and diving along the South Island's West Coast and regularly operates in rough seas across a notorious bar.

The owner can set the boat in the direction he wants and leave the helm.

Described by a professional skipper who conducted sea trials on the boat as the best boat he has ever been on.

The Scott 952 jet unit is superb and offers exceptional perfomance and handling.

Graceline Classic

JPYD is very proud to have been asked to do the hull design on this beautiful boat for the builder Dave Grayson of Gaceline Boats. An absolutely stunning boat. A real head turner both aesthetically and audibly with its Mercury V8 engine.

Viwe and hear the Graceline 581 here:-

Rêvo Beachcraft 601 Pontoon

The Rêvo 601 Beachcraft is a 6 metre aluminium alloy pontoon boat with surf launching trailer. The boat has been built in 3 configurations. Cuddy, centre console and semi-enclosed with forward raking screens. The boats have 1 man surf launching trailers which float with the boat out through the surf. They then anchor the trailer and release the boat. When they return they drive the boat onto the trailer, tie it off and motor the boat and trailer in through the surf. Superb surf launching and retrieval system. The boats themselves are almost unrecognisable as pontoon boats and yet have 500% reserve buoyancy that does not reduce interior space at all. Most importantly the hulls are soft riding as can be seen in the attached video.

Built by Beachcraft Boats, Dunedin.

Rêvo WASP 442 and Rêvo WASP 742 Powercat

Revolutionary new hull form makes for a simply superior boat.

The hull is a new unique design in which we have all the benefits of a cat but in the same beam as a monohull. This gives about 14% more useable volume and floor space for the same length and beam.

The hull rides on a combination of clean and aerated water making it very fuel efficient and soft riding.

More efficient than an equivalent sized monohull, more stable, dryer and softer riding. We can point the boat in any direction in rough seas and leave the wheel. The boat is very very safe!

We see great potential for these boats as work boats, ferries, rescue boats, tenders for superyachts, and superb as pleasure boats providing excellent accommodation and safe handling.

Twin engines widely spaced offer unparalleled piece of mind, safety and control. The boat can be run at low speed without excessive trim angles giveing her a very wide band of operational speed.

We recently launched the Rêvo WASP 742, which is the 7.4 metre version, for a Sydney customer.

It is built of fabricated polyethylene.

The boat floated with 270 mm draft exceeding the design requirement of 300 mm and runs at 34 knots also exceeding the performance requirement of 32 knots.

The walk through forward cockpit is a superb feature and performance and handling are excellent.

Very smooth and quiet and will fully plane at 12.5 knots at a mere 2600 RPM.

Described by a professional skipper aboard at the launching as the best cat he has ever been on by a long way. He said he would like to order a 20 metre version of it he was so impressed.

Colken 451 alloy pontoon

Originally designed for a dealership in Auckland, the boat incorporates all the features his customers told him they wanted in a boat. I designed the boat but the GFC put paid to the build. Martian Marine took on the building of the boats before Colken Engineering bought the building rights for this model.
The pontoons are unique in that they do not encroach on the interior space and yet maintain a reserve buoyancy of 500%. There is a toe-kick on a flat sole making standing in the cockpit very comfortable while fishing leaning against the cockpit sides. Interior space is huge and the boat is very stable. The ride is typical of all JPYD designs. Customers use these boat up to 26 kilometres offshore on the East coast of the South Island.
You can see from the pictures the beautiful job Colken Engineering has done. There are 3 models, open tiller steer, centre console and this cuddy model. Recommended power is 40 to 60 horsepower or can be run as a jet drive as well. For information contact Colken Engineering.
