Emirates Team New Zealand are in a bid to set a new windpowered land speed record. Here’s everything we know about their plans so farNot content with being one of the most successful teams in the history of the America\u2019s Cup \u2013 and current holders of the Cup \u2013 Emirates Team New Zealand is attempting to set a new wind powered land speed record.
\nThe team announced its intention to try for the record in early 2022 and are now well on the way to making an official record attempt.
\nAs of the 23rd May 2022, Emirates Team New Zealand has completed a successful week of testing at Whenuapai Air Base where they have been able to run Horonuku, their speed sailing land yacht, up to nearly maximum load and complete structural and component checks.
\nAs has become a significant part of Emirates Team New Zealand culture, Ng\u0101ti Wh\u0101tua \u014cr\u0101kei (an Auckland-based M\u0101ori hap\u016b in New Zealand) as the iwi manaaki of the team have again named and blessed the craft in its endeavour to be the fastest wind powered craft in history.
\n\u2018Horonuku\u2019 means gliding swiftly across land. Horo means fast or swift movement and nuku is connected to over earth or land.
\nWith a week of testing now under their belts, the team says that in this initial testing week Horonuku has worked extremely well, has been sailed in 15-30 knots and already seen speeds in excess of 140kmph.
\nThe team has another week of testing scheduled before shipping to Australia on 9th June where the planned record attempt will be taking place. During this time there will be some small changes implemented to the steering geometry and wing ballast and finally some testing will take place with the slick rear tyres.<\/p>\n
The windpowered Land Speed record
\nThe current wind powered land speed record has stood for an astonishing 13 years, having been set back in 2009 by British innovator Richard Jenkins in his custom built land yacht, Greenbird.
\nThe 2009 wind powered land speed record run was the culmination of a decade of trying to break the record by Jenkins, who had travelled to a series of locations throughout Australia, Britain, and the United States, but struggled to find suitable weather conditions for him to reach maximum speeds. Jenkins eventually found success at Ivanpah Lak, a dry lake bed in the Mojave Desert, California.
\nHis record-setting run to set a new wind powered land speed record saw him record 126.1 mph (202.9 km\/h) in the Ecotricity-sponsored solid wing-sailed land yacht, Greenbird \u2013 the fifth iteration of the craft that he had built over the many years it took him to break the record.
\nLake Gairdner in South Australia is a potential location for the record attempt
\nJenkins\u2019 new record eclipsed the previous benchmark, which American Bob Schumacher set a decade previously, by just shy of 10mph. It also continued a British tradition for speed that dates to the 1920s, when Sir Malcolm Campbell set several records on land and sea.
\nGreenbird was made entirely of carbon composite materials, and the only metal parts were the bearings for the solid wingsail and the wheels. The enormous power generated by a solid wingsail and a wide wheelbase meant that Greenbird could achieve vehicle speeds up to five times greater than wind speed.
\nSolid wingsails of a similar type to that used by Greenbird are now familiar to many sailors \u2013 even if they remain the preserve of high performance development designs. The solid wing generates lift in the same manner as an aircraft wing and, unlike material sails, does not deform under pressure.
\nA well built and engineered wingsail is typically vastly more efficient at speed than a soft sail.
\nAmerica\u2019s Cup winners to land speed record holders?
\nIt is this incredible efficiency in generating power that has seen wingsails adopted for the America\u2019s Cup. The sail concept was successfully used by BMW Oracle Racing on the giant trimaran in 2010, then also used when the event moved to the high performance AC72 catamarans in 2013.
\nThe kiwis have plenty of experience when it comes to solid wings.
\nAny seasoned fan of America\u2019s Cup racing will know it is \u2013 primarily \u2013 a design, engineering and technology contest. It attracts the biggest names in the world of sailing and can make stars out of the winners but, as with the world of Formula 1 (a sport many Cup teams have formed significant partnerships with in recent years) the team with the fastest boat (or car) usually comes out on top.
\nEmirates Team New Zealand have been totally dominant in the last two America\u2019s Cup cycles so it is unsurprising that they have turned their significant engineering, design and computer simulation skills to trying to become the new wind powered land speed record holders.
\nThe plan currently would see the team take a first run at the record in July \/ August on one of Australia\u2019s vast salt lakes. Lake Gairdner in South Australia or Lake Lefroy in Western Australia are both potential locations.
\nAny 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.
\nGlenn Ashby has been instrumental in Emirates Team New Zealand\u2019s Cup success \u2013 both as part of the sailing team on the water and liaising with design and engineering teams to encourage development.
\nAustralian Ashby came into the New Zealand America\u2019s Cup squad as a performance multihull expert. He has won 3 America\u2019s Cups, an Olympic Silver Medal and 17 World Championships in 4 different classes of boat. Away from sailing Ashby also has a past in land yachts and is a keen motorbiker.
\nHe also shares a long-held interest in the land speed record with ETNZ CEO Grant Dalton. In the lull in the Cup sailing cycle after their 36th America\u2019s Cup victory in 2021, the chance presented itself to try and take on the speed record.
\n\u201cI have never spent so much time on the computer as I have this past year,\u201d says Ashby, who has been working on the project while unable to leave Australia and go to New Zealand due to covid travel restrictions. \u201cBasically, from the point that Dalts said \u2018let\u2019s look at it\u2019 after the finish of AC36, we have been all go.
\n\u201cFirst 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\u2019s Cup objectives financially or resource wise.\u201d

\nThe New Zealand land yacht
\n\u201cIn doing our research and digging deeper and deeper into the intricacies of the design challenges, it became very apparent that Richard [Jenkins, builder of Greenbird] really did an incredible job with his world record design.\u201d explains Ashby.
\n\u201cAs 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.\u201d
\nNew territory
\nWind power will be very familiar to Emirates Team New Zealand, as will the design, technology, complex composites work, aerodynamics, and many other aspects of building a land speed record holder. But what will be a new challenge for the team will be the wheels and tyres, about which they have almost no experience.
\nThe man leading the charge in the area is Mechanical Engineer Tim Meldrum, a mountain biking enthusiast \u2013 one of the key designers behind the legendary Cyclors mechanical system that was so integral to the team\u2019s success winning the America\u2019s Cup back for New Zealand in 2017.

\nThe team will be using a mixture of off-the-shelf wheel and tyre combinations for the outrigger and twin rear wheels, but have custom designed and manufactured their own front wheel in order to get the steering accuracy they need.
\nWith a craft likely to be so similar to Greenbird, it will take everything Team New Zealand knows about marginal gains to beat the current wind powered land speed record. Areas such as machining their own front tyre might just turn out to be the vital advantage they need to set a new record.
\n\u201cThe objective is to design a craft that becomes the fastest wind powered land yacht ever.\u201d said Glenn Ashby.
\n\u201cAnd no one would have ever been that fast in a wind powered craft on or off the water. So that\u2019s a pretty bloody exciting thing to try to become.\u201d<\/p>\n
