Features

Every passage, logged in full.

Nautis records the whole trip: your track, the conditions, the notes worth keeping. Then it turns the passage into an examiner-ready RYA logbook. It all works offline, the moment you leave signal behind.

The log

Every detail, in its place.

Course and speed, wind and gusts, barometric pressure, sea state, the sails you set, the engine hours. Every field a proper logbook asks for, ready the moment you need to write it down.

And room for the note. The squall that came through, the watch handover, the dolphins off the bow. The part you actually go back and read.

RYA G73 export

Your sea time, examiner-ready.

Every trip becomes a logbook in the RYA's own G73 format: miles run, days aboard, your capacity on board, tidal or non-tidal, and the night hours worked out for you from the sun. Export it as a branded PDF or a CSV.

Automatic

The passage records itself.

Your position tracks the whole way. Speed, course and pressure read straight off the phone. And at the interval you set, Nautis records these on its own. The miles and the readings are captured while you sail, not after.

Offline-first

Works with no signal.

Every entry saves to your phone the moment you write it, signal or not. The cloud is only a backup, a way to reach your other devices, and how you share a trip with friends or On Watch. You never lose your sea time, even mid-ocean.

For sailing schools

Get your students logging.

Nautis is in closed beta. If you run an RYA training centre or sailing school, get in touch and we'll get it into your students' hands: a logbook they'll actually keep, that turns their sea time into an examiner-ready G73.
