The rebuilt Nacra 17 tracker keeps a box score for every boat in every race. We ran all 15 races of the 2026 European Championship in Eckernförde through it, along with 6,530 starts from across the season.
Emil Järudd and Hanna Jonsson won the Open Europeans, and the numbers show where they did it. They also turn up two things nobody in sailing had measured before. The tracker then went live for the first time at the NACRA Cup Valencia last week, where the European champions lost the title by a single point.

Best new numbers: the box score
Baseball keeps a box score for every batter in every game. The tracker now keeps one for every boat in every race.
One row per boat covers the start, every mark rounding, places gained on each leg, tacks and gybes, top speed and pace against the fleet. The numbers come from the same engine that draws the race on screen, so what the stats say and what you see always match.
The Marks panel lists every boat at every mark, with places gained or lost on each leg and leg pace against the fleet median. The Moves panel lists every tack and gybe with the meters and the seconds it cost. The charts compare up to four boats on speed, VMG, rank and distance behind the leader. Click anywhere on a chart and the replay jumps to that moment.
The laylines are measured. The tracker draws them from the angles the fleet is actually sailing right now against the measured wind, refreshed every five seconds. It does not use a textbook polar. If fewer than two boats are steady on a tack, it draws no line.
The new Nacra 17 stats page rolls those box scores up into six jerseys, Tour de France style. After the Europeans the boards read:
The white jersey, for the best young crew, goes to the best yellow-jersey score among crews where both sailors raced the U24 Junior Worlds. It is on the stats page with the rest.
Järudd and Jonsson won the title, took yellow and green, and were second on red with 49 places gained after the first mark. Offerman and Houtman won four races, led round the first mark in four, and own the start line: an average start score of 3.18, the best in the fleet.
The red jersey belongs to the other Australian Liddell. Jake Liddell and Niamh Meehan finished 19th overall but gained 54 places between the first mark and the finish, more than anyone. They were often back in the pack at the first mark and spent the rest of each race coming through it. Their season page has it race by race.
Brin Liddell and Rhiannan Brown (AUS 5), the crew that made the top ten at every regatta of the season without a podium, sit fourth on green and fourth on polka-dot. Fast and sharp off the line, every time.
Best minute: the start, one minute in
The Start panel now has a second view. It shows the state of play one minute after the gun.
For every boat it shows where on the line they started (pin, boat end, middle, port tack below the fleet, second row, late or over early). It shows whether they took the favoured end and whether they had clear air at the gun and every 15 seconds after. It shows whether they held their lane, got rolled or tacked clear, and who won each end.
To build it we scored 6,530 starts from seven regattas this season, across the 49er, the 49erFX and the Nacra 17. We then compared each crew’s position at the top mark with their own usual result.
Crews that held a clear lane to one minute rounded the top mark about a place better than their norm. Crews in bad air at one minute rounded a place and a half worse. Winning an end was worth about two places.
Here is the one that will start arguments. Crews that got rolled and tacked away to clear their air lost more than a place on average. Crews that stayed in the lane and fought gained a little over half a place. Sailors are taught that tacking out for clear air is the safe call. On this season’s data it isn’t.
The stats pages turn all of this into a start score for every crew, from minus 3 for an early start to plus 5 for winning an end and holding the lane, averaged over the season. How the start score works.
Biggest number nobody measured before: 64
Nacra 17 sailors get two numbers no other tracker gives them.
The first is flying time: the share of each beat a boat spent up on its foils. In the breezy races at the Europeans, boats flew about 75 to 90 percent of their upwind time. On the light days they flew none of it. The fleet split into two speed groups upwind, one at 8 to 11 knots and one at 14 to 17. The gap between them is the difference between sailing on the foils and sailing on the hulls.

Flying time is a column on the stats page leaderboard. Across the Europeans, Bouwer and Hin flew 74 percent of their upwind time, the most in the fleet.
The second is the splashdown. Any time a boat drops off its foils downwind, the tracker marks it on the map and flags it on screen as it happens. Across the 15 Europeans races the fleet came off the foils downwind 64 times. Twenty-five of those were hard landings, where the boat fell below 6 knots or took more than 30 seconds to get back up to speed.
The Nacra 17 sails three distinct upwind modes, by the way: high and slow when it cannot foil, a medium mode once it foils easily, and a low, fast mode while it is trying to get up. A tracker that assumed one upwind angle would get the wind wrong all race. Ours calibrates from each boat’s relative speed before it estimates the breeze, and its laylines widen and narrow as the fleet changes mode.
Valencia, one week on
Järudd and Jonsson arrived in Valencia as European champions and the crew to beat, and on day two they took the lead. Mateo Majdalani and Eugenia Bosco (ARG), silver medallists in Paris, took it back on Friday with a 3, 1, 1, 3 day that included back to back wins in races eight and nine.
Saturday never got going. There was no wind at all, the last race was cancelled, and the regatta finished after ten of its eleven races. Majdalani and Bosco won on 27 points, Järudd and Jonsson were second on 28, and Micah Wilkinson and Kate Stewart (NZL) were third on 51. Twenty four crews from 17 countries raced.
The difference this time is that everyone could watch it happen live, box scores and all.
Best ending
Every boat in every race now has a box score, and every crew has a season page.
Fifteen races in Eckernförde produced 516 rows of them. Valencia added ten more races to the count, and this time the rows filled in live as the fleet sailed.
