Record your sailing on your phone. Marena, your coach, learns from you and the whole fleet, then turns it into the exact drill to do next. On race day, see the wind in 3D over the real water.
Hit record. GPS tracks every tack, gybe and leg. Add a wind sensor, heart-rate band, or just a quick note.
Your numbers join everyone's, anonymously. It learns what speed to expect, how much a tack really costs, and what each place is like.
Pick what to work on. Marena reads your data and builds the drill in the app: the course, the timer, the plan. Then it checks if it worked.
A forecast gives you one number for a few kilometres of water. On the racecourse the breeze squeezes, bends and dies around every headland, bridge and pier. Marena now works that out, and shows you what is coming.
A fluid simulation on a graphics processor works out how the forecast breeze actually flows over the real terrain, bridges and buildings.
Storm cells on radar and when their gust front reaches your race area: the gust, the shift and the lull after. Fronts coming or leaving. The sea breeze's odds, onset and peak. Refreshed every 5 minutes.
See the weather → Pressure & shiftsThe water coloured by more or less breeze than the open course, and by the shifts the land puts in. Every zone gets a sentence. Plus whether today's shifts swing back and forth or keep going one way.
See the zones → Race replayUpload a GPX or Vakaros track after the race. See the wind along every leg, and your VMG against your boat's targets.
Open Race Replay → Race venuesThese venues get a fresh 3D field every hour of the racing day, checked against buoys, piers, airports and sailors' own wind readings.

The more you sail, the better the coaching. The more everyone sails, the better it gets for everyone.
Every session, wind reading, forecast and note goes in. Nothing to type if you just hit record.
Your history, the fleet's combined numbers, and what each beach or lake is like. Anonymous and combined, never personal.
A drill built in the app, with how it will be measured. Next session, the loop checks whether it worked.
Your speed against what the fleet's data says is possible in that wind and angle. A fair yardstick, not a guess.
Every forecast is compared with the wind sailors actually measured at that spot. The most accurate model becomes the default there.
Pins drop automatically and are named after the nearest beach, marina, lake or bay. Typical wind by hour builds up as people sail there.
"I want to be faster from the windward mark onto the reach." Marena reads your own sessions, the fleet, and the venue, then answers with a drill she can build in the app for you.
She bobs, changes colour with her mood, and blows the odd bubble.
