Racie Puts the Regatta on the Phone

Field notes

Racie is organized around a phone-based sailing workflow: record a track offline, synchronize it after returning to shore, and optionally broadcast a boat’s position during a race. Its analysis layer is intended to turn the track into sailing-specific measures such as tacks, VMG, starts, and wind shifts. The page shows a sample Baía Norte chart at 1:50,000 scale, cites Brazilian Navy, NOAA, and DIHIDRONAV chart sources, and describes a night mode designed as a separate red-on-black palette.
