ETNZ History Part 1
THE HISTORY OF ETNZ - PART 1 As the 36th America’s Cup draws ever nearer, our lengthy alliance with Emirates Team New Zealand has once again piqued a keen interest in the yachting world from within the Hydraulink community. As such, we have decided to celebrate the return of the upcoming Cup season with a series of emails diving deep into New Zealand’s history in the America’s Cup. Over the next few months, we’ll take you on a journey into the past and back again, with an in-depth insider’s view of Team New Zealand’s triumphs and disasters. TE KAHU - THE HAWK With the team’s recent reveal of their new custom designed and built test boat, ‘Te Kãhu’, we thought this the perfect chance to take a look at this new boat, its purpose and what exactly it means for the team. With a hydraulic system on-board that utilises Hydraulink hoses and fittings, this is a project very near to our hearts and we’re incredibly proud to have contributed to the build of this ground-breaking yacht. Purpose-built by ETNZ’s dedicated team of over 30 skilled boat builders, Te Kãhu was created to allow the sailing crew to continue their on-wa- ter development program without delay, whilst Te Aihe is packed up and shipped to Europe in preparation for the first of the America’s Cup World Series events beginning in April. While the series’ rules on test yachts dictated that this boat be limited to a length of 12m or less in comparison to Te Aihe’s larger 20.7 metre hull, don’t be fooled by her size – Te Kãhu is every bit as technologically advanced as Te Aihe. -

Hydrofoil, Rudder, and Strut Design Issues
International Hydrofoil Society Correspondence Archives... Hydrofoil, Rudder, and Strut Design Issues (See also links to design texts and other technical information sources on the IHS Links Page) (Last Update: 11 Nov 03) Return to the Archived Messages Contents Page To search current messages, go to the Automated BBS Correspondence Where is Foil Design Data? [11 May 03] Where do I go for specifics about foil design? As in how do I determine the size, aspect ratio, need for winglets, shape, (inverted T vs. inverted Y vs. horizontal V), NASA foil specification . My plan calls for a single foil fully submerged with all control being accomplished with above water airfoils (pitch, roll, direction). Everything above water is conceptually set, but I have limited understanding / knowledge about foils. I understand that there are arrangements combining a lower speed and higher speed foil on the same vertical column, with some type of grooving on the higher speed foil to prevent cavitation at limited angles of attack. With respect to the website http://www.supramar.ch/ there is an article on grooving to avoid cavitation. I anticipate a limited wave surface (off shore wind) so elevation could be limited, and the initial lifting foil would be unlikely to be exposed to resubmersion at speed. Supramar is willing to guide/specify the grooving at no charge, but I need a foil design for their review or at least that seems to be the situation. I have not actually asked for a design proposal. Maybe I should. Actually it is hard to know if my request would even be taken seriously. -
Spring 1988 International Sunfish® Class Association Vol
windwardle The Official Newsletter of the Spring 1988 International Sunfish® Class Association Vol. II, No. 6 · ~ : . .I RETROSPECT: Jack Evans Looks Back (Part 1) ~ by Charlot Ras-A/lard It's hard to believe that the Sunfish (and its predecessor, the Sailfish) dates back 40 years. Twenty five North American champions have been crowned, and countless sailors from the America's Cup on down have raced the 'Fish at some point. Few had the vantage points that Jack Evans had. The scoreboard shows he garnered four Sailfish national titles between 1967 and 1970, was runner up at the 1974 Force 5 North Americans, won the first Super Sunfish North American Championship in 1975, sailed the C-Ciass catamaran, Weathercock, at the 1972 Little America's Cup in Australia, and, of course, earned the right to sail with a silver Sunfish on his sail at the 1972 North Americans at Sayville. Evans gained another perspective through his work " wearing many hats" at Alcort from 1969-1977, most notably as Class Secretary from 1969-1975. He later went on to: design and market the Phantom, become a Regional Sales Representative for Hobie, write the book " Techniques of One-Design Rac ing, " and testify in a Congressional hearing on the merits of Micron 33 while working at International Paint, Inc. Currently, he is employed by Beckson Marine, Inc. in Bridgeport, Connecticut. ) caught up with Jack at the 1988 New York Boat Show and later at his home in Guilford, Connecticut, reuniting after a "few" years. In part 1, I take a look back at the Sunfish and its past. -
Update: America's
maxon motor Australia Pty Ltd Unit 1, 12 -14 Beaumont Rd. Mount Kuring -Gai NSW 2080 Tel. +61 2 9457 7477 [email protected] www.maxongroup.net.au October 02, 2019 The much -anticipated launch of the first two AC75 foiling monohull yachts from the Defender Emir- ates Team New Zealand and USA Challenger NYYC American Magic respectively did not disappoint the masses of America’s Cup fans waiting eagerly for their first gl impse of an AC75 ‘in the flesh’. Emirates Team New Zealand were the first to officially reveal their boat at an early morning naming cere- mony on September 6. Resplendent in the team’s familiar red, black and grey livery, the Kiwi AC75 was given the Maori nam e ‘Te Aihe’ (Dolphin). Meanwhile, the Americans somewhat broke with protocol by carrying out a series of un -announced test sails and were the first team to foil their AC75 on the water prior to a formal launch ceremony on Friday September 14 when their dark blue boat was given t he name ‘Defiant’. But it was not just the paint jobs that differentiated the first two boats of this 36th America’s Cup cycle – as it quickly became apparent that the New Zealand and American hull designs were also strikingly differ- ent.On first compar ison the two teams’ differing interpretations of the AC75 design rule are especially obvi- ous in the shape of the hull and the appendages. While the New Zealanders have opted for a bow section that is – for want of a better word – ‘pointy’, the Americans h ave gone a totally different route with a bulbous bow that some have described as ‘scow -like’ – although true scow bows are prohibited in the AC75 design rule. -
Costs and Benefits of Hosting the 34Th America's
LEGISLATIVE ANALYST REPORT: COSTS AND BENEFITS OF HOSTING THE 34TH AMERICA’S CUP IN SAN FRANCISCO EXECUTIVE SUMMARY The America’s Cup is the premier sailing event in the world. Hosting the 34th America’s Cup in San Francisco, an event reported to be the third largest in all of sports behind the Olympics and the World Cup, would make San Francisco one of only seven cities in the world to have hosted an America’s Cup. In addition to the prestige of such an event, hosting the America’s Cup would also bring significant economic benefits to the region. The Budget and Legislative Analyst wants to make it very clear that the disclosures made in this report, pertaining to the estimated costs and benefits to the City and County of San Francisco, are not for the purpose of determining whether the America’s Cup should be held in San Francisco. We clearly recognize the importance and prestige of hosting such an event in San Francisco. However, it is the responsibility of the Budget and Legislative Analyst to report the facts to the Board of Supervisors. On February 14, 2010, at the 33rd America’s Cup in Valencia, Spain, BMW Oracle, a sailing syndicate (or team) based out of the Golden Gate Yacht Club in San Francisco, defeated the defending syndicate to become the winner of the 33rd America’s Cup. Under the rules governing the America’s Cup, the winner of the America’s Cup is entitled to select the race format, date, and location of the next race. -
Performance of Wing Sail with Multi Element by Two-Dimensional Wind
Bulletin of the JSME Vol.10, No.2, 2015 Journal of Fluid Science and Technology Performance of wing sail with multi element by two- dimensional wind tunnel investigations Hiroyuki FURUKAWA*, Alexander W. BLAKELEY **, Richard G.J. FLAY ** and Peter J. RICHARDS ** * Department of Mechanical Engineering, Meijo University 1-501 Shiogamaguchi, Tenpaku-ku, Nagoya 468-8502, Japan E-mail: [email protected] **Department of Mechanical Engineering, University of Auckland 314-390 Khyber Pass Road, Auckland, New Zealand Received 30 April 2015 Abstract Following the 33rd America's Cup which featured a trimaran versus a catamaran, and the recent 34th America's Cup in 2013 featuring AC72 catamarans with multi-element wing sail yachts sailing at unprecedented speeds, interest in wing sail technology has increased substantially. Unfortunately there is currently very little open peer- reviewed literature available witha focus on multi-element wing design for yachts. The limited available literature focuses primarily on the structures of wings and their control, rather than on the aerodynamic design. While there is substantial available literature on the aerodynamic properties of aircraft wings, the differences in the flow domains between aeroplanes and yachts is significant. A yacht sail will operate in a Reynolds number range of 0.2 to 8 million while aircraft operate regularly in excess of 10 million. Furthermore, yachts operate in the turbulent atmospheric boundary layer and require high maximum lift coefficients at many apparent wind angles, and minimising drag is not so critical. This paper reviews the literature onwing sail design for high performance yachts and discusses the results of wind tunnel testing at the Yacht Research Unit at the University of Auckland.
