Competing with a Crystal Ball

Published on January 22nd, 2019

With driverless cars soon to dominate the roadways, the sport of Sailing continues to head that direction too. With instruments guiding us to the perfect start, and routing software choosing the ideal course for offshore teams, the buoy racers also have tools that have taken over thinking.

This has been creeping for some time. Ingo Buell’s routing system helped Jochen Schümann plot his route to Olympic victory in his Soling at the 1996 Games in Atlanta, with Buell Software continuing to develop tactical technology to help sailors win.

As its name implies, SailTokyo is a system aimed at those looking to win gold at the next Olympics in Enoshima less than two years from now. Among its clients Buell Software can count the Olympic sailing teams of Belgium, Germany, Switzerland (and some larger sailing nations who prefer to keep their anonymity) along with the host nation of Japan, whose sailors surely know the venue better than anyone.

Yet SailTokyo’s application is much broader than Olympic sailing or the next Olympic venue.

For any race venue in the world, SailTokyo creates the means for sailors, coaches and support staff to build a clearer picture of what the current and the wind are doing, and how the two forces are interacting with each other. The tool can be applied as much to the realms of big boat racing, and even the America’s Cup, as to the high-performance dinghy scene of the Olympic classes. And its scope is not just Tokyo but any racing venue in the world.

“We designed SailTokyo as a cloud-based team solution to prepare your sailing team for the Olympic Games – Tokyo 2020, Marseille 2024 – and all the World Sailing events and Olympic class world championships,” said sales manager Yvette von der Burchard. “But we have been delighted to see the software so well adopted and appreciated by other high-level sailors and race campaigns.”

In the Etchells fleet, for example, SailTokyo has established itself as a must-have for the top performers such as Olympic silver medallist and multiple champion Steve Benjamin from the USA.

“We started working with SailTokyo at the Etchells Worlds in Cowes 2016,” notes Benjamin. “The app was crucially important there and since then has continued to get better and better, and easier to use. The app helped us win the 2017 Etchells Worlds in San Francisco and the beta model in Brisbane worked great, too.”

Indeed, Martin Hill’s winning team at the 2018 Brisbane Etchells Worlds also relied on SailTokyo to help plot their way around the racecourse.

Andrew ‘Dog’ Palfrey is one of the most sought-after coaches at the top end of the sport and has been using SailTokyo since the Dragon World Championships in La Rochelle three years ago. For him and his clients, running the routing software helps provide clarity and certainty when planning a strategy for an upcoming race.

“I guess everyone’s brain works in a different way, but for me the routing aspect of the software is very useful,” said Palfrey. “We can all look at arrows overlaid on a chart, but can we really pinpoint which side is favored all the time? I can’t honestly say I could do that. Sometimes it’s obvious, you know, it’s shallow water over there, but a lot of the time the potential gains or losses across the course are quite subtle, yet they’re still important.

“When I’m running the software, I’m not too bothered about the result itself, but the result will certainly help quantify how important the current is on that day. When it’s start time and the pressure is on and you need to make clear decisions, just having that quantitative result logged in your mind is a real benefit.”

Grant Spanhake is another coach who numbers the TP52 Alegre amongst his high-profile clients. “Last season in the TP52 fleet I got together with a few coaches for other campaigns – people like Tony Rey, Cameron Dunn, Timmy Haynes, John Cutler – and we ended up using the app on our phones and our iPads out on the water.

“We were all committed to make two, three or four current measurements in different areas across the racecourse and then all the collated data would appear on each of our iPads. It’s a great collaborative tool, because it meant that three or four boats could cover the whole racecourse very quickly.

“It gave us the ability to generate an accurate current field around the racecourse that we could all share. It gives the tacticians a lot more information to make their calls on which way to go, which is particularly useful in a complex venue like Cascais, which can feature some pretty strange current movements.”

James Lyne is another TP52 coach, in his case for Quantum Racing, although the new America’s Cup challenge, American Magic, is increasingly taking his attention. SailTokyo is forming an integral part of the Cup campaign, but Lyne is not at liberty to say exactly how.

“Some of the America’s Cup stuff that we’re doing with SailTokyo I’m not really going to talk about, but it has certainly been very useful for the Quantum Racing TP52 campaign over the past season,” shared Lyne. “We’ve been using it as a predictor rather than just relying on our own memories and saying, ‘Oh, remember that Tuesday in 2015 at Palma Vela? Today’s a synoptic day like that’.

“As well as using our own experiences of a venue, we can now bring in SailTokyo and we can input the different models and run the boat up the course. So it’s a whole new way of looking at the day forward.

“From my perspective, as a coach, we are always looking a day behind us. We’re always having a debrief about the day behind us whereas SailTokyo is great because it’s like a pre-briefing about the day ahead of us.”

As well as enabling teams to forecast the likely conditions for the day ahead, the latest version of

SailTokyo also includes some very strong debriefing features, to help sailors and coaches see how – with the benefit of hindsight – they might have played the day differently.

SailTokyo processes readings of currents, wind and tracks. These data – measured on a sailing boat or by coach boats during the race – provide the backdrop for analyses of the theoretically best course. Tracks can be overlaid with this optimal course to gain a deep insight into where things went right and where they could have gone better.

One of the challenges for new users of SailTokyo is to grasp its full capability, but one of the best ways into the software is to find a particular feature that appeals to you and make it work for you until it becomes part of your routine.

Lyne can recall his first encounter with SailTokyo during the build-up to the 2015 edition of the Melges 20 World Championships in San Francisco. ‘We built our own polars and inputted those into the system. We were down on the Berkeley Circle where the current was doing two things, flooding in from the west but also making a big bend, out to the north. So it’s a big, effectively a right bend of current. This can make it hard to get your head around the whole cross-current aspect of the area.

“I suppose that’s where we learned more than anything because we sort of didn’t believe the output to start with. And obviously with the Samba Pa Ti program and the Wild Man program, we had two boats, identical gear, world-class sailors and we spent quite a lot of time each day ‘ground-truthing’ the tidal prediction. In other words, if start time for the championship was at 1pm, then at 1pm each training day we’d have one boat go left up the course, one go right and we tested the course for a hundred days.

“We felt the need to do this validation, this ground-truthing process, because it was our first time using the software and it was predicting things that, when you look just at the tidal data, you wouldn’t think are correct. But the more we sailed there and tested it, the more we realized just how incredibly accurate were the deltas being predicted by SailTokyo.”

John Kilroy’s Samba Pa Ti would go on to win those Worlds comfortably while his 12-year-old son Liam would come third, just a point off second place, skippering Wild Man. There were many good reasons for the success of the program, but Lyne says SailTokyo played a key role in giving the two crews great confidence in their strategic planning and decision making.

Just how Lyne and his cohorts at American Magic will be using SailTokyo to try to win the 2021 America’s Cup, we will perhaps have to wait a few years to see, however, Lyne is very excited about the possibilities.

“Of course we could have developed our own in-house solution, but time is always the most precious resource and SailTokyo gives us a lot of what we need in a package that is very customizable,” notes Lyne. “There was really little point in us spending time trying to do our own thing when we already have a great relationship with Buell. Ingo and Yvette have always been very open to new ideas and we enjoy working with them.”
