Wind AI
Studies how the wind behaves during the race, and race after race. It offers the crew an optional bold route — a bet on the side of the course that pays — always stated as an option, never as an order.
Faster. Sharper.
The coach that has the numbers.
Navigatek builds AI-augmented racing software — a range that goes from free weather to live coaching by six AIs on board, under licence.

LIVE
Audio coaching on board
- COACHING Coaching: Bear away firmly to hold 40° … next tack in ~500 metres … Wind steady.
- VERDICT Gust absorbed: +0.5 kt of speed (peak 12 kt). Good absorption, keep going.
- ALERT Plan C, ⚠️ TACK NOW — VMG collapsed (0.5 kt against 5.1 on the other tack) — header too costly
- VERDICT Well played, you tacked — I had just recommended it (12 s earlier) … Wind will shift −2°
- VERDICT Tack completed in 9 s to regain speed (excellent), with an estimated loss of ~1 s against a perfect tack.
- COACHING Coaching: 🟢 Mark rounded — speed first, heading 243° to mark 3.
- COACHING Coaching: Bear away 10° to hold 152° … Wind will shift +13°.
- COACHING Coaching: Heading good … next gybe in ~1600 metres … Wind will shift +11°.
Real messages, spoken aloud on board during a race.
At the heart of the range: Navigatek 6Ai.
The most advanced product: six specialised AIs that race with the crew. Everything that follows has been in service on a J/70 since summer 2026 — the proof is in the sample report.
- EquipEveryday sensors: the innovation is in how they are read.
- MeasureEvery sensor characterised, and watched by the others.
- UnderstandPolars, VMG, a wind map of your water, six specialised AIs.
- AdviseA call spoken aloud, with its reason.
- ImproveA report in numbers: every manoeuvre timed and its loss counted.
Measured, never guessed.
Every recommendation comes from a deterministic tool: dual GPS at 10 Hz, onboard wind sensor, polar curves, drift maps learned on your own water. The artificial intelligence computes none of it itself — it reads those results and explains them to you in plain language, during the race or after.
If the data does not exist, Navigatek says so. It never invents a wind, a VMG or a time to the line.
Navigatek does not replace your hardware. Already have instruments? It builds on them (integration planned). Missing some sensors, or have none at all? It supplies them, up to the complete kit. Then it steps in during the race, aloud, and checks afterwards whether the advice helped.
It augments the crew. It does not replace it.
No AI touches the helm, the trim or the call. Navigatek widens what the crew can see and measure, so the decision — which stays yours — rests on facts instead of impressions.
Six AIs. One crew.
Six specialised systems work together, share the same data and speak the same language — live coaching during the race, structured debrief afterwards. Together they raise the crew's tactical ceiling.
Race-director AI
Speaks out loud on board: live advice through the boat's speaker while you sail. After the race, it answers any question about what happened, in conversation.
Tactician AI
Trained on tactical computation: VMG, polars, laylines, and headers. It knows when a shift is worth a tack — and when it is not.
Post-race analyst AI
Produces a detailed report of every decision, manoeuvre and condition — so the debrief is structured and built on observable facts rather than memory.
Sensor data engineer
Checks every sensor continuously, corrects its measured biases and sets a bad reading aside: all six AIs work on sound data.
Sailboat racing expert
The crew's racing know-how — tactics, trim, rules. Reads the press and research every day, and answers like an expert.
And together, they correct themselves.
The set of AIs learns, finds its own mistakes and corrects them at every training cycle on the water and after every race. What was wrong last Sunday is measured, named and fixed.
250+ adjustable parameters, used to refine the AI models and improve what they deliver.
The innovation is not in the sensors. It is in how they are read.
The sensors 6Ai can read today are everyday ones — GPS, an industrial compass, a barometer, an anemometer — and the whole boat fits in about $1,000. That is not where the innovation lies: it lies in how they are interpreted. Every sensor is characterised on board, cross-checked by the others, demoted on its own if it drifts — and its readings become decisions.
Without
Numbers on a display that have to be read, trusted and turned into a decision — while helming.
With Navigatek
The same measurements, checked against one another and turned into a call spoken aloud, with its reason.
- 2.9 mmedian gap between two generic GPS units on the same boat
- 3.1°median gap between the industrial compass and the GPS track
- 0sensors taken on trust from a datasheet: every precision is re-measured at each outing
A precision that is measured and published, not claimed “equal” to marine instruments: the side-by-side comparison is the next step. Already have instruments? Their NMEA 2000 integration is on the roadmap. Every sensor in detail: the engine page.
Everything measurable, measured.
The AIs share one sensor suite and follow every action on board, second by second.
- GustsRise predicted before it hits, with its lead time.
- Tacks & gybesDetected, timed, and costed in seconds lost.
- Speed breakdownsA drop the average hides — caught and dated.
- True windDirection, strength, shift and oscillation period.
- Heel & attitudeCompass, gyroscope, calibrated heading.
- PositionDual GPS, ground track, distance to the line.
The debrief writes itself.

1 · Synthesis
Race 4 of 4 October 2026: 46.7 minutes, southerly wind (161.3° on average, 11.35 kt). 10 legs, 5 tacks and 4 gybes. Pointing is optimal, but the wind turned 63° over the race, skewing the measured angles. The boat slid 8.0° to leeward of its course, with a suspect compass offset of 3.0°. The coaching missed 9 shifts out of 19. Vent's safeguard serves persistence, not the model. No speed breakdown, but costly gybes (30.8 s at 10:37:33).
The anomalies found by the coaching audit, from one report to the next: 52 on 30 August (out of 18 checks), 7 on 12 September, 3 on 4 October (out of 22). We publish our errors — and we fix them.
And the analysis that comes with it.
The report runs 12 pages: conditions, start, speed, manoeuvres, wind, tactics, AI-coaching audit, fleet, progression, crew decisions and an action plan.
Autonomous on board. No cloud, no tokens.
Specialised race algorithms, run by AIs on hardware dedicated to you — entirely on board, or remotely when there is network on the water. No token bill, no growing subscription.
The reasoning is simple: running race operations on cloud AI would be far too expensive, and the network to reach it may simply not be there. A lake, a bay, an offshore leg — coverage is never a promise. So the system has to stand on its own: to cut the cost of a race, and to depend on no network at all.
The problems it is built to solve
Spot an anomaly nobody sees
A rope trailing in the water, weed on the keel — a drag that costs speed the whole leg while the crew looks for the fault everywhere else.
Measure every manoeuvre
From the plain tack to the harder ones — absorbing a gust without losing the groove — detected, timed and scored against a perfect execution.
Remember the wind across the course
Learn how the breeze behaves as the boat moves through it, so a bold tactical plan can be offered — the side that pays, argued with measurements.
Read any sensor worth reading
Heel, drift, heading, wind — through sensors of every kind, including ones never meant for boats. If a sensor exists and can be useful, Navigatek can read it and put it to work.
Who it is for.
Four products, and the expertise that built them — to integrate in whole or in part. Four ways in.
01Racing teams
Professional and amateur teams who build — or commission — their own race tools, and who are looking for deep expertise in the method rather than one more product.
Advanced expertise to fold into your development methods, for the technology you use during a race as much as for the technology used to debrief it.
- What you already haveA review of your tools, your data, and how decisions are actually made on board today.
- Where the measurement is missingWe name what is decided on impression for want of a number. That is where the gain sits — not in one more sensor.
- The method, not the recipeHow to instrument, how to verify, and how to refuse to conclude when the data does not allow it — the part that cannot be copied.
- Handover to your teamYour people leave with the approach and can run it again without us. Expertise that creates a dependency is not expertise.
Your involvement: your technical team and your race data. Expertise is handed over, not rented indefinitely.
02Sailing schools & academies
Schools that want a debrief in numbers without building the technical chain — or buying marine instruments for every boat.
A complete post-race coaching kit, integrated at your school: sensors, recording and report, ready to serve as teaching material.
- What the session has to produceWe start from the lesson you teach, not from the sensor we could fit.
- The kit, fitted to your boatsSensors and recording installed, ready to use. Nothing to operate during the session.
- The debrief becomes the lessonEvery manoeuvre timed and costed, every decision dated: the report is the material, and it no longer has to be prepared.
- Your instructors own itThey read the report and use it without us — the condition for the kit to still be useful two seasons from now.
Your involvement: your boats and one typical session to calibrate the kit. During the lesson, nothing: the instructor keeps their eyes on the students.
03Makers of racing technology
Instrument makers who want AI in their products — or the software that makes a sensor trustworthy: calibration, cross-checking, self-diagnosis.
Two questions, one answer: how to integrate AI into your products, and which capabilities from this project to take over directly, under licence or as a technology partnership — the coaching, or the engine that makes an everyday sensor trustworthy.
- What your instruments already knowAn inventory of the data you capture, of what is missing, and of what AI can genuinely draw from it.
- What can be taken as it standsAmong what this project already runs in a race, what integrates into your products without being reinvented — and what does not lend itself to it.
- Measure before promisingWe establish on real data what is actually reachable, and we say so when it is not. A capability announced and never delivered costs more than one refused.
- Integration, then proof on the waterNothing ships on a bench result alone: it races first, then goes into your instruments.
Your involvement: your data and your product constraints. The measuring and the proving happen on our side.
04Sailing clubs
Clubs that want simpler and richer races, a body of water better known every season, and administration that runs itself — with no instrument budget or expensive software.
Tools for the club's activities — races, weather, planning, administration —, several of them free today, which grow richer with every race. For the boats that want to go further, Navigatek 6Ai on the same water.
- Simpler races, and richer onesNavigatek Juge and Navigatek Bord, free and coming soon: start, clock, early starts and published results, each boat tracked by its crew's phone. No tracker to buy.
- Water that is learnedThe fleet's tracks, aggregated and anonymous, learn the lake's wind race after race. Navigatek Meteo, free, turns them into a wind map that knows your water better every season.
- Planned courses, and bolder onesIn Navigatek Meteo, the committee places its marks on the map and picks the race time: the fastest route is computed in the forecast wind, leg by leg. Enough to set the marks where the race will be tactical.
- The club, administeredNavigatek Club: members, memberships, billing, treasury and reserve fund, with an AI assistant and bookkeeper. On request; the club has to be accepted.
Your involvement: one volunteer on the committee, one in the treasury. The rest is set up with you, at the dock.
Built on the water, not in a lab.
Navigatek was born on Lac Tremblant, aboard a J/70, over a full season of racing. Every function was tested in a real race before it was added to the product — not the other way round.
The watch: what sailing publishes, read for you.
Every morning, Navigatek reads the sailing press and the blogs, keeps only what a racing crew can actually use, and says why. Each item carries its source link — so you can always go back to the article.

What to take from it: On a course closer to shore, and therefore shiftier, a bad start can be made up by working the shifts and the puffs.
