The definitive digital logbook for modern mariners. Seamlessly track your voyage data, manage weather conditions, document vessel maintenance, and coordinate your crew with precision instruments.

SailLog is free. Navigation, logbook, engine, checklist, weather, and tides features are always available at no cost. AI features (Skipper Advisor and logbook diary generation) include 5 free analyses per month; an unlimited monthly or annual subscription is available.

What devices does SailLog support?

SailLog requires an iPhone with iOS 17.0 or later. Data syncs automatically via iCloud across all your Apple devices connected to the same account.

Yes. Navigation data, logbook, and boat information are stored locally on the device and synced via private iCloud. SailLog does not track users or share data with third parties.

How does Skipper Advisor work?

Skipper Advisor is an AI assistant that analyzes the entered route, current weather conditions, and your boat profile (length, cruising speed, range) and returns a GO / CAUTION / NO-GO assessment with recommended waypoints, wind warnings, practical tips, and the optimal departure window.

How do I enter a route?

In the "Route" tab you can type the departure port and destination, or use your current GPS position as the starting point. The AI calculates the route and displays it on the chart.

Can I use Skipper Advisor without an internet connection?

No. Skipper Advisor requires an active connection to query the AI model and download real-time weather conditions.

How do I log engine hours?

In the Engine tab, press "Start engine" when you turn it on and "Stop engine" when you turn it off. Hours are automatically accumulated and update the maintenance counters.

What are maintenance alerts?

SailLog monitors oil change (every 100h), filters (200h), impeller (300h), alternator belt (400h), and anodic zincs (annual). When you approach a deadline the app shows a warning; when it has expired, a red badge.

Can I customize the checklist?

Yes. In Checklist → "Manage items" you can add custom entries, choose the category (Hull, Engine, Safety, Legal Equipment, Radio/Electronics) and mark them as critical.

What happens if I leave critical items incomplete?

If there are incomplete critical items, the app warns you before allowing the captain's signature. You can choose to ignore the warning, but it will be recorded in the session report.

How does AI diary generation work?

In the Logbook tab, after recording the day's entries (wind, heading, speed, sea state), you can press "Generate diary". The AI reads the data and produces a first-person narrative in the style of nautical memoirs, in the language selected in settings.

Can I edit the generated diary?

Yes. The generated diary can be edited directly in the app before exporting or sharing it.

What does the AI subscription include?

The AI subscription unlocks unlimited route analyses with Skipper Advisor and unlimited logbook diary generation. Without a subscription you have 5 free AI analyses per month.

How do I cancel my subscription?

The subscription is managed directly from iPhone settings: Settings → [your name] → Subscriptions → SailLog AI. You can cancel at any time; access remains active until the end of the paid period.

Can I use my personal API key instead of the subscription?

Yes. In Settings → AI Assistant you can enter your Anthropic (Claude) or OpenAI (ChatGPT) API key. With a valid personal key, no subscription is required.

Where does the weather data come from?

Marine weather data comes from Open-Meteo (GFS/ECMWF model) and includes wind, gusts, Douglas sea state, waves, swell, pressure, and visibility.

Is tide data accurate for my port?

Tides use the WorldTides service which covers thousands of worldwide reference stations. Accuracy depends on the proximity to the nearest station to the port searched.

How do I activate MOB?

During an active sailing session, the red MOB button is always visible at the center of the bottom bar. Press it immediately in case of a man overboard: it saves the GPS coordinates, starts the timer, and shows the return route in real time.
