New Organization & Leadership


A Message from Jack LeFort, Vice President 12mR North American Fleet

Hello fellow 12 Metre Owners, Crew Members and Enthusiasts!

Jack LeFort

Jack LeFort

As a young kid watching these magnificent boats race in Narragansett Bay, I never dreamed that one day I would own KA-10 and have the joy of sailing in one of the most revered and iconic classes of this century. The past 3 years have been a blast!

As we move into 2020 and beyond our #1 commitment is to help get as many 12mRs as possible out on the water racing. Before I get into some key changes in the 12 Metre Yacht Club and North American fleet, I want to extend several well earned and sincere THANK YOUs.

First to Commodore James Gubelmann for building and stewarding the 12 Metre Yacht Club. Jimmy’s passion and commitment to 12mR racing here in Newport along with the invaluable talent and depth of knowledge of SallyAnne Santos, has created a communication and social foundation which will help springboard us to the next level of participation and enthusiasm for all things 12mR. We are grateful and enthusiastic that SallyAnne will continue her work with the NA fleet and 12MYC. She is an invaluable asset to our team. Jimmy and SallyAnne, Thank You for all your hard work theses many years with the 12 Metre Yacht Club.

Congratulations to outgoing N. American Fleet Captain, Peter Gerard and his incredible 2019 12mR Worlds committee at Ida Lewis Yacht Club for winning U.S. Sailing’s St. Petersburg Trophy for the best managed regatta of the year! This world-class event set the stage for a fantastic rebirth of the 12s here in Newport. Due to the overwhelming success last year, we are looking to host another World Championship in Newport in the near future. We hope it will be as well attended and fun as the last; way to go Peter and team!

Changing of the Guard:

We are very grateful to Commodore Gubelmann and Fleet Captain Gerard. Both are stepping down from their leadership roles with the 12mR Yacht Club and North American Fleet respectively, but have agreed to ‘stay near’ and ‘help out’ as we transition to a new organization model and management structure. With their departures we have retained a professional fleet manager as is done by other successful, sustainable fleets.

Linda Lindquist-Bishop

Given our vision and plans for the future we feel it is imperative that the North American fleet makes this commitment. So I am thrilled to announce that Linda Lindquist-Bishop has joined us as Fleet Manager and Executive Director of the 12 Metre Yacht Club. Linda represents what is terrific about our sport both on and off the water. She will be combining our fleet racing activities into the 12 Metre Yacht Club, which will bring new focus and opportunities in membership, events, participation and partnerships. Linda is our go to person for all your questions and ideas.I ask you to join us in welcoming Linda to our 12mR community.

2020 Racing and Boats:

The 2020 N. American fleet schedule, found here will feature 4 sanctioned events this season, including our North American Championship in late September. In addition to scoring on a boat-for-boat basis we will introduce a handicap system to give all boats the opportunity to be competitive and have the joy of winning. This handicap system is under development and will continue to be a work in progress. Our goal is to get as many boats on one starting line as possible. We are encouraging increased owner participation in the strategy and management of the fleet as we look to innovate and build on our current base of success.

After chartering a boat for the New York Yacht Club’s 175th Anniversary, we are thrilled to have Mr. Okura and his Sled team join the Newport 12mR fleet. Mr. Okura has purchased Freedom (US-30) and will balance 12mR racing along with his TP52 program in the Med. Mr. Bertelli and his team are currently giving Kookaburra II (KA-12) an upgrade and will be joining us on the water in June. We also welcome new owners to our strong charter fleet, comprised primarily of Traditional division boats; they are the backbone of 12mR experiences here in Newport. If you haven’t yet sailed on a 12, I encourage you to experience a day on the water on these boats. As Brad Read, afterguard crew of New Zealand, KZ-3 said to me once, “There is nothing like sailing these boats to windward in 12 knots– it’s just breathtaking.” A bucket list item for sure!

While we welcome new teams and revitalized programs – our hearts are heavy with the loss of Freedom (US-30) owner, Charles Robertson. Charlie exemplified everything that was good and right about our sport. He gave many sailors their first opportunities to compete in the big leagues; he was passionate about racing and the legacy of 12mR yachts, and he loved each day he spent on the water. Charlie will be greatly missed by all of us.

This is a tremendous building year for our 12mR fleet and community here in Newport!

In closing I want to thank everyone who is part of our history now… and into the future.

Jack LeFort,
Vice President North American Fleet
Owner, Challenge XII (KA-10)

Message from the Commodore

Dear 12mR Friends,

12MYC Commodore James Gublemann at the 2017 12 Metre North American Championship, Newport, Rhode IslandWhat an incredible summer we had! Looking back, I have to say that Newport put on one hell of a show for the 2019 12 Metre World Championship. The feedback that we have received from our International competitors has been extraordinarily positive. So much so that US Sailing recently selected Ida Lewis Yacht Club for the 2019 St. Petersburg YC Trophy– awarded for outstanding race organization of the 12mR Worlds– based primarily on comments provided by participants.

As you may know, North American Fleet Captain, Peter Gerard and I are stepping down from our leadership roles. We will continue to support organizational restructuring that combines the N. American fleet with the 12 Metre Yacht Club. Challenge XII (KA-10) owner, Jack LeFort was elected by fellow 12mR owners as the new ITMA North American Vice President and Fleet Captain. He will be assisted by Linda Lindquist-Bishop, now engaged as our N. American 12mR fleet manager.

Since the 2019 Worlds, there has been much change in the wind for the Newport fleet. Meanwhile our organization, leaders and members have been acknowledged and awarded for excellence. I sincerely thank each of you for your participation, assistance and support of the 12mR Class throughout my tenure as Commodore.

The Third Rule– Before and Since

David Pedrick

The Twelve Metre Class has operated under the so-called Third Rule since 1933. Using an unchanged rating formula for more than 80 years, although with some changes in secondary technical details, Twelve Metre designs have evolved significantly within the Rule’s envelope.

The basic structure of the (First) Rule was created in 1906, with a similar formula as the Third Rule, but having additional terms that were subsequently discarded and changes made in the weighting of other terms.

Rating = (L + B + 12G + 3d  + 13SF)/2 = 12.000 m

The basis of L, d, S and F are close to the way that they are used in the current Rule, although S was based on gaff rigs. L included girth corrections for the overhangs at the ends of L, similar to now. G was a midships girth measurement taken under the keel, which forced keels to reduce their draft forward of the rudder post – a poor design influence.

12, by the way, was meant to be the approximate waterline length, but LWL has grown toward 14 m in evolutionary design development.

Shortcomings of the Rule were apparent early on, and a lot of effort went into improvements after WW I. The Second Rule in 1920 abandoned maximum beam B and replaced it with a minimum beam limit. The weighting of G was halved, the factor on d was reduced to 2 and √S was taken at full value. The denominator was changed to 2.5 to keep existing yachts’ ratings close to 12.

Also, the reference plane for L was raised from the LWL to 112% of Class rating above the LWL, the lower end for measuring d was set at 1212% of rating below LWL. The fore triangle area was discounted by a factor of 85%. And a formula for minimum displacement was introduced, along with prohibiting hollows in the topsides.

The Second Rule is actually quite close to the Third Rule except for one term. The girth G under the keel was eliminated in the Third-Rule formula, and the denominator re-set to 2.37 to keep ratings close to 12. With these most recent changes in the rating formula in 1933, the Third Rule became the familiar:

Rating = (L + 2d – F  + √S)/2.37 = 12.000 m

There are many detailed requirements and restrictions within the text of the Class Rule, but separate rudders and trim tabs, and then winged keels, have nonetheless broken through design barriers while fitting within these same, basic Rule parameters. Even Appendix E, created in preparation for the America’s Cup Jubilee in 2001, is built on this basic Rule formula with credits for age, design type and propulsion.

The Rule’s girth measurements in the overhangs and the separate displacement-length formula cause the long overhangs and U’d end shapes common to all Twelves. The specified location of the midships d measurement, also coupled with displacement-length, forces the hull’s slack-bilged shape. And the fixed, maximum heights of the mainsail and fore triangle dictate the rig. All pretty simple and durable since the Second Rule of 1920, yet leaving liberty for a century of distinctly different designs.

Joop Sloof Presentation, 5/1/16

Joop Sloof - The KeelMembers of the 12 Metre Yacht Club, Newport Station gathered at the Clarke Cooke House last evening for an event organized by 12MYC member, Dan Nerney. Retired Dutch fluid dynamacist, Joop Sloof, presented a slide show revealing his part in the design of the winged keel of the 12 Metre Yacht Australia II based on his newly published book “Australia II and the America’s Cup – The untold inside story of the Keel.”  As the photos reveal, the event was attended by many luminaries of Newport’s America’s Cup halcyon days including sailors, designers, race officials, supporters, photographers, members of the press, and NYYC Commodores- both past and present.
