‘Bloody Exciting’

When Lymington’s own, Richard Jenkins, smashed the land speed record for a wind assisted craft back in 2009, he set a benchmark that few thought then and even less think now can ever be beaten. On a timed-run on the dusty Lake Ivanpah, deep in the Mojave Desert of San Berdanino County, Jenkins strapped in to his Star Wars-esque ‘Greenbird’ and clocked an astonishing, other-worldly 126.1mph and took the then record of 116mph held by Bob Shumacher’s ‘Iron Duck’ to another generational level.

Such was the performance leap amidst extraordinary, once-in-a-lifetime conditions that it’s no surprise the record has stood for the last 13 years and rather like a Bob Beamon or New York Yacht Club sporting record, it’s one that could be set to go the distance. Could it be beaten now? Team New Zealand think so…



The record itself was the culmination of a 10-year quest for Jenkins that was dogged by wheel failures and systems issues as the crucial connections between vessel and surface and the interface with the wind was thoroughly examined in the harshest conditions.

The breakthrough for Jenkins though was aloft with his wing/tail/tab system (I wonder what happened to that theory?) that allowed precise control of the angle of attack of the wing to produce the maximum power at the maximum efficiency. It was an heroic effort that set a bar for human endeavour at speed under sail on land that pretty much sealed the record books for what looked like an eternity. As records go, this was one that would take a mighty, mighty effort to better.



Well not so fast. Glenn Ashby, the Aussie skipper of Emirates Team New Zealand and a man with speed coursing through his veins has had his eye on this record for a while and as the America’s Cup entered its hibernation period, he found sympathy from a fellow speed-freak with ants-in-his-pants in Grant Dalton.

Together they saw a window of opportunity in the build schedule and the chance to pull the boatbuilders off those hydrogen things and into something that has a modicum of relevance to the Cup in its new guise. Whilst the brain-box A-Team designers immersed themselves in the minutiae of the Protocol, a select few led by Guillaume Verdier were corralled to the latest man-cave project and it was all systems go.



Ashby’s been stuck in Australia due to the daftly zealous New Zealand border-control so it was a Zoom project largely to try and find where improvements could be made on the Greenbird record. As ever, at the very apex, it’s not about revolution but evolution and a sincere acknowledgement that even if they got everything right, the record is unlikely to be smashed (as Jenkins did) but incrementally improved. It’s a simply massive task that Team New Zealand and Glenn Ashby have taken on where chances of success are in the slim-to-none range but that’s just the odds that this unbelievable team and its boss, like.

But where can they improve on Greenbird? Has the wheel and bearing technology moved on enough for success? The answer is: slightly. Has the understanding of aero really changed? Well, not changed but refined. Are modern-day construction techniques and materials use better than before? Definitely maybe. And what about up top? Well that’s where the speed will be found and with Team New Zealand’s knowledge of wing dynamics and construction, it’s here where the crucial mph might just be discovered. If they do, it will be marginal gains all round and the perfect conditions must prevail. I wish them luck.

The cynics will suggest that this is all a side-show and carp on about the money or the team’s focus but set that nonsense aside and I think it’s just great that the Kiwis are at full bore with projects like this.

You can be absolutely assured that they’re on their AC game but it’s these kind of side-projects that create something a whole lot more. The team isn’t sitting twiddling its thumbs, it’s inspired, it’s thriving and it’s engaged. This is a blueprint of what modern-day AC teams are set to become and it’s so much more than just the America’s Cup. Ineos Sports Group are cross fertilising talent from a wide range of sports. Red Bull Alinghi are having more fun across more disciplines than you can shake a stick at and American Magic are in the early foothills of building something so much more than just an American entry in the AC. Hats off to them.

The full press release from this privately funded (read: Matteo de Nora) venture is well worth a full airing and if you get 10 minutes this weekend, have a watch of the video that I’ve posted at the end. It’s a fascinating insight into not only the land speed record but the dynamics of Team New Zealand, the personalities, the culture, its guiding principles and principals and the inner workings of this stellar sports team:

Some childhood dreams can become realities, others remain just that: dreams. For a 10-year-old boy growing up in Bendigo Australia, his childhood dream was to go faster than anyone else had done, powered by the wind. 

Speed has always been at the centre of Glenn Ashby’s existence, on yachts, motorbikes- or land yachts. The quest for speed has won him 3 America’s Cups, an Olympic Silver Medal and 17 World Championships in 4 different classes of boat.

After the 36th America’s Cup victory in 2021 the stars aligned for both Ashby and Emirates Team New Zealand, who he has been an integral part of for over 10 years, bringing together his lifelong ambition with the depth of design, technology and innovation of Emirates Team New Zealand. All the while utilising the window of opportunity that existed with the usual lull in AC activities during the transition from the 36th to the 37th America’s Cup.

Emirates Team New Zealand has always commissioned external contracts to keep the design team sharp and engaged during these periods. So, when the independently funded project to attempt to beat the Wind Powered Land Speed World Record emerged it was not hard to find willing designers, engineers and shore crew to put their talents to the test from being fastest on the water of the America’s Cup to being fastest on land ever. 

The speed record attempt has been a common point of discussion for a number of years between Ashby and ETNZ CEO Grant Dalton, who himself has had a long-held interest in such a record shot. “The wind powered land speed record is something I have always been interested in, so when bringing a design challenge like this into ETNZ I knew it would be beneficial on a number of fronts to keep the technicians and the innovators of the organisation engaged during a down time with new, complex technical issues to solve with a cool project.” said Dalton

Glenn Ashby has been like a cat on a hot tin roof on the end of dozens of Zoom calls back to the Emirates Team New Zealand base unable to re-enter New Zealand for the past 10 months. “I have never spent so much time on the computer as I have this past year,” explained Ashby. “Basically, from the point that Dalts said ‘let’s look at it’ after the finish of AC36, we have been all go. First job was a two-week in-depth feasibility study to ensure enough of a global understanding that this was something that could be done in a positive way for ETNZ and would not impact the team and its America’s Cup objectives financially or resource wise.”

Since then, the core group of Guillaume Verdier, Romaric Neyhousser, Benjamin Muyul, Jeremy Palmer, Romain Gard, Tim Meldrum, Sean Regan, Adrian Robb, Jarrod Hammond and Dave French have been working through the new design and engineering challenges entirely focused towards beating the existing Wind Powered Land Speed World Record of 202.9km/h (126.1m/h) which was set in 2009 by Richard Jenkins in Greenbird.

Ashby paid tribute to Richard Jenkins whose record he is trying to conquer. “In doing our research and digging deeper and deeper into the intricacies of the design challenges, it became very apparent that Richard really did an incredible job with his world record design.” said Ashby. “As a team we explored some pretty creative and innovative conceptual ideas in the quest for more speed, however in the end our design and performance principles evolved into a concept reasonably similar in basic layout to the existing record holder, which really emphasised to us what a huge challenge this will be.”

Without a silver bullet in terms of a revolutionary design, and very much like what is predicted in the 37th America’s Cup with the next generation of AC75’s, the gains will come down to the small improvements and refinements that add up to overall advancements and success. “Like the America’s Cup we just need to be doing it better across the board by utilising our experience, skills and tools gained as a team to date,” explained Ashby. And then, like sailing, there is always the weather gods and doing everything we can to be ready when the right conditions are presented at the location.”

Emirates Team New Zealand Principal Matteo de Nora, who is a significant supporter of the world record attempt, is clear on why now is the right time for the challenge.
“We are seeing some very close collaborations now where the design is crossing into Formula 1 territory with Ineos Britannia and Mercedes and Alinghi and Red Bull Racing for a start. This isn’t a coincidence and is focused on the top line speeds and lessons that can be learnt the faster you can go. So, this project will be beneficial in continuing to evolve and learn so much more in the aerodynamic realm which was a significant factor in AC36.” said de Nora.

From a design and engineering perspective, Guillaume Verdier explained “this project is a really compelling one for all of us involved. There are a lot of similarities to what we do with fast sail boats in terms of the aerodynamics and structural forces, construction methods, materials etc, so we are well placed in many respects. But without doubt, no boat we ever design will go anywhere near as fast as we need our land yacht to go. So, with the increase in speed comes increased complexities, but we are sure these are complexities that we can learn from so we can make our next AC75 go faster.”

The obvious element of uncertainty and point of difference for all the Emirates Team New Zealand designers is tyre technology and the dynamic forces associated with tyres on the ground, as opposed to hydrodynamic forces on foils in the water.

“This is the big unknown for us,” explained ETNZ Mechanical Engineer Tim Meldrum.
“Tyres on a flat salt surface going at over 200km/h is a whole lot different to foils in the water at over 50 knots. The rules stipulate we must run on a flat natural surface. The best ones we know of where it can be windy are dry salt lakes. With the tyres being the only point of contact to the salt it is a pretty important factor in finding the sweet spot in maintaining sufficient grip- with the least amount of rolling resistance.”

Our craft when compared to a speed record motorised car has a lot of differences. Firstly our “motor” – a wing in our case really delivers a small thrust force compared to a racing combustion engine. So, anything working against that thrust – wheel rolling resistance and aerodynamic drag has been a high priority to reduce if we want to hit high speeds. Secondly our wing creates a lot of side load over the main back wheels – so we need to provide grip to keep it tracking straight. A downforce aerodynamic wing like those used in F1 to assist cornering grip would rob us of too much speed, so we have opted to add variable ballast weight to allow us to tune our grip level. Extra weight mainly affects our acceleration time but does not compromise aerodynamic drag. The trade-off is we can go faster but we end up using more runway to get to our top speed. Luckily our racetrack is 8km across.”

Another contradictory problem to the norm in the America’s Cup is around weight. In the AC75’s the less weight in the boat the easier it will be to fly and faster it will be. With a land yacht, weight is a positive in certain respects explains Construction Manager Sean Regan:“In land speed, weight will be our friend if used in the right location. So, we can refine our construction techniques that account for additional weight in certain aspects and not be so focused on weight savings. On the outrigger pod we are actively adding weight or ballast to counter the wind force on the wing sail, without which, the craft would just tip over. Not something we want for Glenn approaching such high speeds.”

But like a scale measuring gold, the weight still needs to be precise. Too little the outboard tyre will come off the ground losing contact, too much it will add unnecessary resistance and lose valuable clicks of speed. It is these sorts of design problems that will have to be overcome in the typically condensed lead up to a shot at the World Record in July / early August which Ashby and the team are working towards attempting on one of Australia’s vast salt lakes with Lake Gairdner in South Australia or Lake Lefroy in Western Australia as potential locations.

Any world record needs to be stringently verified and will require officials from the North America Land Speed Association to measure and record the run with a specific set of rules that must be adhered to in order to qualify for the World Record. For now, the craft is already under construction at the Emirates Team New Zealand build facility on Auckland’s North Shore. “The build is scheduled for completion in late March, for assembly and commissioning and preliminary testing in Auckland subsequent to that.” said Sean Regan.

“The plan is to then pack the craft and equipment into containers and ship it all to South Western Australian and truck to the record attempt location where a small team will be based from July for testing and then ultimately a shot at the World Record speed run. Obviously the objective is to design a craft that becomes the fastest wind powered land yacht ever.” said Glenn Ashby.

“And no one would have ever been that fast in a wind powered craft on or off the water. So that’s a pretty bloody exciting thing to try to become.”
