Nautog

The boat logbook for liveaboards and cruisers. Track passages, engine hours, maintenance and costs. Works offline. Built by a sailor who lives aboard.

Your boat. Your data. One app.

Nautog is a practical logbook and maintenance app for liveaboards, cruisers, and weekend skippers. Built by a sailor who lives aboard, for people who actually use their boats.

WHAT IT DOES

Passage logging Log trips with route, weather, crew, notes and photos. Quick entry from the cockpit, full edit when you're alongside.

Engine hours Track engine time properly. Service intervals update automatically as hours tick over, so you always know when the next oil change or impeller is due.

Maintenance tracking Plan, schedule, and tick off jobs. Each task shows a clear status: green when you're sorted, amber when it's due soon, red when it's overdue. No more spreadsheet guesswork.

Cost dashboard See where the money actually goes. Fuel, parts, marina fees, insurance, surveys, antifoul. Filter by month, year, or category.

Offline-first Designed for life on the water. Everything works without signal. Syncs when you've got data again.

Photos and videos Document jobs, damage, parts, anchorages. Stored on your device by default, with optional cloud backup on Pro.

PDF export Need a service log for a survey, insurance claim, or selling the boat? Export a clean PDF of any section in seconds.

WHO IT'S FOR

Liveaboards staying on top of systems. Cruisers logging passages and maintenance between ports. Owners who want a real record of what's been done, what's due, and what it's costing.

If you've been keeping notes in a paper diary, a Google Doc, and three different apps, this puts it all in one place.

PRICING

Free to start, no credit card needed. Three months of full Pro access on signup, so you can use it through a real season before deciding. Pro is available from the Nautog website after the trial ends.

PRIVACY

Your boat data stays yours. Photos and videos are stored on your device unless you choose cloud backup. We don't sell or share your data.
