TF35: FLIGHT CONTROL

A New Class Launches on Lake Geneva

Their take off was a bit delayed but the newly developed foiling TF35 fleet recently met on Lake Geneva for the first of two training weekends. The sessions provide sailors, class organizers and the development team an opportunity to see their vision in action, and trial a format for future regattas. For North Sails, these early training days serve as a chance to analyze the performance of the new TF35 sails.

The TF35 is built on an ambitious design brief; bringing top-level foiling to a wider range of sailors. While the idea of an accessible, high-performance foiler sounds like a strange pairing, a big focus of the training weekend was testing out and then dialing in the boat’s flight control system, which makes the platform more stable and safe. A mere 6 knots of TWS downwind are needed for take-off and the TF35 gets foiling upwind in 8 knots TWS. The flight control system brings stability and safety to the platform, addressing the class’s wish to make a high-performance foiling experience available to more owners.

Lake Geneva is known for varying conditions, but the weekend presented ideal weather for dialing in the TF35. Arnaud Psarofaghis, sail designer and Alinghi co-helmsman said: “Our specific wind conditions on the lake are really challenging in terms of sail range, boat can accelerate quickly, boat speed can vary from 12 to 20 knots within 2 knots of TWS.”

The much anticipated training session saw dream conditions on Lake Geneva, allowing the race committee to complete nine races in winds ranging from 4 – 12 knots. It was a unique opportunity for each of the seven TF35 crews to assess their level and progress within the fleet after training independently over the summer months.

Summarizing the weekend, North Sails Suisse director Pierre Yves Jorand said, “It was a very rewarding weekend we were able to test the TF35 in different sail configurations. The objective of the series is to have boats that offer the great experience of foiling in the typical Lake Geneva conditions. It’s now up to us to optimize the sail combination and boat set up to maximize the level of fun and performance of the boat in the lead up the 2021 TF35 Trophy Championship.”

North Sails has been deeply involved in the development of this new class and our lofts in Switzerland and France worked together to outfit teams with North 3Di.

Patrick Mazuay, North sail designer, member of TF35 Class design team responsible for sail development explains: “We have seen a great improvement already in just one weekend from all of the crews. As one of the sail suppliers, all of us at North Sails are thrilled to see the positive development of everyone on the water. We now have the advantage of the October training session to improve and tweak the sail configuration.”

The overall feeling on sails from everyone involved at the end of the three days training is of great satisfaction, both performance and robustness wise.

Coming up next on October 9-12 is test event #2. Learn more about the class here.

NORTH SAILS RENEWS INTERNATIONAL PARTNERSHIP WITH CAPE 31 CLASS

World’s Leading Sailmaker continues its support of the Fast Growing, Owner Driver One Design Class North Sails is proud to have worked closely with the Cape 31 Class since launching the first boat in 2017, developing the optimal sail wardrobe for One Design and IRC racing. The Cape 31 is a high-performance grand prix design, asymmetric boat designed by internationally renowned yacht designer Mark Mills. The boat has proven itself as an exhilarating one design boat that planes downwind in over 13 knots and rates well under multiple rating systems, making it attractive to many sailors. The Cape 31 Class began racing beneath Table Mountain in Cape Town, SA but has taken the global sailing scene by storm in the last two years. With over 30 boats racing in the UK and several heading to the US, the Mediterranean, and Hong Kong, there are now worldwide class calendars forming for 2023 and beyond. David Lenz, North Sails designer, notes; “It’s awesome to have been involved with the Cape 31 class in the UK since the start. Picking up from the excellent work done in Cape Town, we had a great starting point for the sail designs. Since then, as with any new class, there has been tremendous progress as we work to understand what makes these boats go fast and how to use our technology, experience, and passion to produce the fastest sails in the fleet.” David Lenz is not only a Cape 31 designer but has also been very successful racing in the class, including winning the 2022 Race Circuit overall on Russel Paters’ Squirt. Additionally, the class is filled with North Sails designers and experts, which results in theories being tested firsthand with developments and advancements being made weekly. Commenting on the partnership, Tor Tomlinson Cheney, of Cape 31 Class, shares; “North Sails has worked closely with the class since its inception and has been a major factor in the success of the class in the UK. Their support is invaluable, and we are pleased to extend our partnership with North Sails to an International level.” The North Sails Cape 31 inventory is fully optimised for handicap and one design class racing and consists of one all-purpose 3Di Raw Carbon Square Top Mainsail and three 3Di Raw Helix Jibs. All 3Di sails have carbon leech battens and come ready to race. Downwind there are four spinnakers which all use a string drop system: an A1, A2, and A4 for running, plus an A3 for reaching. As the class expands globally, North Sails is working to ensure that the best sail package can be provided to teams worldwide. Get in touch with North Sails expert Ben Saxton, Cape 31 class leader at North Sails, to learn more about the class and available sail options. READ MORE
