Every role aboard, measured and improving.
Sailing Performance turns the data your boat already produces into feedback for the people sailing it — individually, by role, and as a crew.
Onboard AI that coaches the crew,
not just the boat.
Most sailing software shows you numbers and leaves the reading of them to you. Sailing Performance works out what they mean aboard, and says it to the one person whose next decision it changes.
- No refit — your existing NMEA network
- Runs entirely on the boat, fully offline
- Advisory only, receive-only by construction
Your current instruments and data, now powered by local AI.
Masthead wind, boat speed, depth, heading — whatever is already on your network. Sailing Performance reads what you have and does the thinking on the boat, not in a data centre.
Sail the boat faster.
The race side: targets, shifts, and the cost of every manoeuvre.
- Polar targets and VMGTarget speed and angle for the conditions, and how you are tracking against them.
- Shift callsLift and header called as the breeze swings, with gust and lull separated from the trend.
- Manoeuvre analyticsEvery tack and gybe measured for recovery time and distance lost.
- Race geometry and laylinesWhere the corner is, and what the next leg looks like from here.
It talks to you.
Wind, shifts, laylines, time to the mark, polar percentage — called into your ear as it happens, so your eyes stay on the boat and the water.
Everyone hears what they need.
A screen is one route, not the only one. Calls go to the person whose job they change, in the form that suits where they are standing.
- Auditory firstScreen, headphone or speaker — whichever suits where a crew member is standing.
- Optimised information flowEach call routed to the people it affects, not broadcast to everyone.
- A view per roleHelm, tactician, trimmer and bowman each get their own picture.
- Communication and safetyManoeuvre briefings, role checklists and SOPs, delivered when they matter.
From the dock to the debrief.
Briefing before you leave, feedback while you sail, assessment when the sails come down — and the trend across a whole season. One programme, one record.
Run the programme around it.
Before the dock lines come off, and after the sails come down.
- Pre-race briefingThe plan, the course and the roles, shared before anyone leaves the dock.
- Post-race analyticsWhat happened — by leg, by manoeuvre and by person, across the season.
- Crew coordinationWho is aboard, their assignment, and the device each person is on.
- Runs entirely on the boatReceive-only and fully offline. It cannot write to your network.
A picture built for each position.
Role displays served to any browser on the boat's WiFi — sunlight-readable by day, red-on-black at night. Every call is also available as audio.
Whole fleets, replayed and compared.
The same engines that read one boat read a whole fleet — every boat, every leg, scored on the same terms.
Whole fleets, replayed and compared.
The same pipeline that reads one boat reads all of them — live during the session, and afterwards leg by leg.
Polars from the trim you actually sailed.
Depth, twist and entry angle read off the sail at every height, with the airflow across it — so the polar you are measured against comes from how the boat was really set up that day, not a number from a table.
Polars from the trim you actually sailed.
Depth, twist and entry angle are read off the sail at every height, with the airflow across it. So the curve you are measured against is built from how the boat was really set up that day — not a number from a table.
Your polar, and what you did against it.
The curve the boat is capable of, and the record of how close you actually got to it — session by session, across the season.
See where the weight is.
Cameras aboard read crew position and movement directly, so hiking and weight placement stop being matters of opinion.
In development, alongside the simulation work below.
The same intelligence.
A bigger deck.
Forty metres and up, the crew questions are identical: is everyone improving, is everyone briefed, did anything get lost between watches. Observation-only, worded conservatively, and never as an instruction.
Safe operation, for crew and guests.
Above forty metres the job changes. It is about running the vessel's people well: everyone briefed, everyone coordinated, and everyone able to reach each other.
Advisory only. Not a navigation, collision-avoidance or safety system; emits no COLREG directives; not a replacement for a qualified watchkeeper, radar, ECDIS, AIS or certified alarms.
Everything that gets the crew to the boat.
Travel and arrivals, accommodation, dietary requirements, uniforms and kit, shore events — the logistics of running a crew, managed in the same place as their performance.
The programme starts long before the dock lines come off.
Running a crew is travel, beds, kit and dietary requirements as much as it is sail trim — managed in the same place as their performance.
- Travel and arrivalsWho is flying in, when, and what happens when they land.
- AccommodationWhere the crew are staying and who is sharing.
- Dietary requirementsHeld once, against the person, and carried through the programme.
- Uniforms and kitSizes, issue, and what is still outstanding.
- Shore eventsThe parts of a regatta that happen off the water.
- Crew and devicesWho is aboard, their role, and which display or earpiece each has.
Everyone aboard gets better.
Role-based displays served to any screen on the boat — sunlight-readable by day, red-on-black at night for dark-adapted vision. Each person sees their own picture.
Read the boat. Think aboard.
Tell the right person.
Data is normalised, analysed and put through inference on the boat, then each conclusion is routed to the people it actually affects.
Nothing leaves the boat, and nothing is invented: an input that goes stale produces an explicit unavailable state rather than a guess.
However that person can best receive it.
The same call reaches a different crew member a different way. What suits the bow does not suit the nav station.
- Smartwatches
- Phones
- Bluetooth earpieces
- Fixed onboard displays
- Tablets and temporary screens
The displays are web pages on the boat’s own network, so a regatta setup can be retrofitted temporarily and taken off again, and crew can use their own phones and watches rather than kit you have to buy. The honest constraint is battery: over a long day, keeping personal devices alive is what needs planning, not the software.
AI-Powered feedback that knows your role onboard.
Helm, trimmer, pit and mast, navigator, bowman — each position sees what its own job is measured on. The same engine carries the briefing and checklist for every manoeuvre, and prompts the crew on what to check as conditions move.
Rehearse the regatta ashore.
The same engines that read a real yacht’s instruments also drive our simulator, so a crew can sail a regatta on land — every role, every manoeuvre — and replay it exactly afterwards.
- Race it, and be judged on itTake the helm on a windward–leeward course against other boats, scored on the racing rules: start sequence, marks, right of way, penalty turns, finish.
- Your own role, trained for youEvery position aboard has its own place in the session. Each person trains on the job they actually do rather than a generic view of the boat, and the whole crew sails the same race at the same time.
- Your yacht, your proceduresThe 3D model and the manoeuvre procedures can be adapted to a specific vessel, so a crew trains on their own boat, running their own SOPs — not a stand-in.
- Or one boat eachSailors can each take a boat and race one another. It runs on a single machine on the local network, with no internet needed.
In development. It runs on a machine in the room today, and it trains crews — it is not certified training.
A whole crew, ashore, sailing the same leg.
Fifteen people in a room, one boat on the big screen, each of them on their own station — the same engines that read a real instrument network driving all of it.
This is not a game.
It is a simulation built for performance and for safety. Everything in it is there because it changes what a crew does on the water, not because it makes the boat more fun to drive.
- The same code path as a real boatThe onboard product reads the simulator through exactly the pipeline it uses on a real yacht. What a crew trains against is what they will see on the water.
- Performance from real certificatesBoat speed comes from published ORC and ORCsy rating certificates, with the source stamped into every polar file — not numbers we invented to make it feel fast.
- It replays byte-identicallyEvery session is recorded and replays exactly: the same race, the same result, every time. That is what makes a debrief a record rather than an argument.
- Skill is pricedSteering hard costs speed. Trimming well is measurably faster than the autopilot. Doing it properly is rewarded, which is the whole point of training on it.
What each sailor actually sees.
Everyone works from their own device, showing the job they are there to do.
And what the room sees.
One console runs the session; one screen carries the race for everybody in it.
The boat, in the engine.
We are developing the 3D side with Unreal Engine 5, building interactive experiences from outside the boat and from on deck, for racing and for training. Captured from the engine as it runs; the developer overlay has been cropped away and nothing else was touched.
More to come.
