NautNav
Navegação Marítima Inteligente
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
NautNav is the copilot that keeps you off the rocks. The "Waze of the sea" for sailors and powerboaters: from planning at the marina to arrival at your destination, with safety first.
Here the unit of measure is the demonstrably valid route, not the pretty route. Every track runs through a safety system that rejects paths crossing land or shallow water before you cast off.
GO OR NO-GO?
Check wind, waves, swell, tide, visibility and temperature in real time and make the Go/No-Go call clearly. The day's conditions sit right on the home screen, next to the map.
ROUTES THAT PROVE THEMSELVES
Set origin and destination and get a route validated meter by meter. The Safety Kernel works with a coastline mask, bathymetry and real obstacles (dikes, breakwaters, piers) to keep your keel clear of the bottom.
NAVIGATE AND RECORD WITHOUT THINKING
In free navigation mode, your trip is recorded by GPS automatically and becomes a logbook. Speed, distance and time at sea, all logged.
YOUR FLEET IN YOUR POCKET
Register each vessel with cruising speed, top speed, tank capacity and fuel burn. Keep your boat's data at hand when it's time to plan.
DIGITAL LOGBOOK
Review every passage with map replay, distance covered and total time at sea. Your time aboard, organized.
THE FLEET IS THE PROOF
The more boats sail a region, the better the route gets. The community corroborates real paths and reports hazards, turning the experience of those who went before into intelligence for those about to go.
OFFLINE MAPS
Download entire regions and navigate without relying on signal. Coverage along the coast of Brazil and destinations like the Caribbean, Mediterranean, Portugal and the US East Coast.
MADE BY SAILORS, FOR SAILORS
Trilingual (Portuguese, English and Spanish). An interface built for precise reading under harsh sun, on your phone, at sea.
