Recording that doesn’t need a signal
Hit record and put the phone away. The whole track is logged with the screen locked and keeps recording with no internet. Whatever was stored uploads by itself once you are back ashore.
Brazil’s biggest sailing app
Racie records your sail from the phone’s GPS, streams the race live to whoever stayed ashore and gives you the debrief in a sailor’s words. Nautical chart, night vision and five languages, with nothing to install on board.
It will be free on iPhone and Android.
No rented tracker, no extra sensor, no subscription to record. Just the phone already in your pocket.
Inside
The app’s screens, drawn here with sample data. The look is the same: blue and white, glass panels, and the information always on top of the chart.

What it does
Live tracking, debrief, chart, social, season and club. Each of those layers exists on its own out there, and none of them talks to the next. Racie is the join.
Hit record and put the phone away. The whole track is logged with the screen locked and keeps recording with no internet. Whatever was stored uploads by itself once you are back ashore.
One phone per boat and the whole fleet shows up on the map, in real time, for the people on the beach. Standings update themselves while the race is still running.
At the end you don’t just get a map. You get how many tacks you made, what each manoeuvre cost, where the shift came in and how your start went.
Your position on official charts from the Brazilian Navy, NOAA and DIHIDRONAV, with a distance and bearing ruler. Navigation aid: it does not replace the official chart.
When it gets dark the whole app turns red on black. It is not a filter on top: it is a second palette, drawn in full.
Your sailor profile, your registered boats, your season in miles and hours. Post photos, follow other sailors and push your sails to Strava.
Live racing
Every boat broadcasts its own position. Whoever stayed ashore follows it in the app and watches the course draw itself, with standings updating on their own. The club rents no tracker.
After the race
The report is made of sentences with a number inside, not of charts for an engineer. And when the track doesn’t allow a wind estimate, the app says so, instead of showing a pretty number that is false.
Where there’s time to gain
Two beats hit the layline far too early. Leaving no tack for the end costs metres.
Manoeuvres
Tacks 8 · Gybes 4 · Average loss 17 m · Best manoeuvre 6 m
Strong point
Favoured end: pin (7°). Distance to the line at the gun: 4 m.
Pace
Beat 1: 4.9 kn of gain · 96% of best. Beat 2: 4.4 kn · 87%.
The analysis runs on your phone, on the track that is already there. It does not depend on sending your sail to any server.
Nautical chart
Three layers: nautical, the official navy chart and satellite. A distance and bearing ruler in two taps, a compass that orients by heading or by north, and the chart source always written on screen.
Racie does not replace an official nautical chart or navigation equipment. Do not navigate by it.

Night vision
Scotopic vision, the rods, the ones that work in the dark, is virtually insensitive to wavelengths above ~620 nm. So at nightfall the whole app turns red on black: not one white, blue or green pixel on the screen. It is the same reason aircraft cockpits, observatories and chart tables use red light.
And because roughly one man in twelve cannot tell green from red, no information in the app rests on colour alone: the state is also written out and shown by an arrow.
The whole site swaps palette, exactly like the app.

Pure black background: on an OLED screen an off pixel emits no light at all, and that is extra battery on a long race.
The start
Distance from the bow to the line, from the bow and not from the phone. Time to cross computed from closing speed, not from speed over ground: a boat parallel to the line never reaches it. Favoured end, bias in degrees and the advantage in metres.
ILCA and Optimist forbid electronic instruments on board, and the ILCA test is what the device is capable of, not what you use it for. The start assistant is born disabled and is only unlocked class by class. Always check your Notice of Race first.
ON TIME
The timer jumps to the nearest whole minute when you tap on the gun, because the committee rarely starts on the exact second of anyone’s watch.
Privacy
That is why the privacy zone exists: a circle around your home port inside which your track arrives cut off for everyone, except you.
The track disappears inside the circle you draw around your marina.
The location stored inside a photo is stripped on upload, and an automated test proves it.
Every sail is public, followers only or private. You choose one by one.
Download everything of yours whenever you want and close the account from inside the app, without asking anyone.
Clubs and marinas
Publish the calendar, take entries and stream the race to the beach. The live map is free. The per-boat tracking bill that today blocks live coverage of a club race simply does not exist here.

SEARCH
Survey closed on 2 September 2026: the CBVela calendar, 55 Brazilian yacht clubs checked one by one, state federations, the sailing press and 276 notices of race read in PDF.
Five languages
Each language carries the racing vocabulary of its own country (cambada, tack, virada, empannage, virata) and the RRS wording as it is used there. The numbers change with the sentence: 7,4 kn in Portuguese, 7.4 kn in English, 7,4 nd in French.
Who builds it
Racie was not born in a meeting room. It was born from two people who spend their weekends wet.
Ocean sailing
Theodora PradoThe first woman to complete the Cape2Rio single-handed, the crossing from Cape Town to Rio de Janeiro. Some 3,500 miles of South Atlantic in 29 days, aboard a 31-foot boat built in 1981, with four-metre waves on the final stretch. She left a career in finance at 23 and, in four seasons, added five Atlantic crossings. She sets the bar for what Racie has to survive out at sea.
Product and engineering
Fernando ZomerOffshore sailor and developer. He races aboard Pangea, of the Iate Clube de Santa Catarina, overall champion of the 51st Ilhabela International Sailing Week and winner of the 70th Santos to Rio Race in RGS Overall, 53 hours upwind against 15 to 25 knots. Ashore he runs EZA Engenharia, in Criciúma, Brazil, and founded Easy Alert. He wrote Racie from scratch: the app, the server and the sailing maths.
There is no signal out at sea. The track lives on the device and the upload queue waits on disk with growing back-off. No point is lost because 4G dropped on the way back from the mark.
When the track doesn’t allow a wind estimate, the card says so and asks for the data. The estimate carries a confidence from 0 to 1, and the app behaves differently below 0.5.
The sailing maths (VMG, cost of a manoeuvre, bow-to-line distance, scoring) is covered by automated tests that run on every change.
Apple, Google or Strava. And if you want, your sails go to Strava on their own.
