At sea, at anchor, in a marina with no signal — your logbook is always available. On the Free plan your data stays on your device; Sync and Share add the KnotWise Cloud, hosted in Switzerland. — NMEA LIVE INTEGRATION — Connect KnotWise directly to your onboard instruments. GPS position, wind speed, heading, depth and log — all flow automatically into your log entries. Enter once. Use three times: logbook record, passage statistics and customs document from a single source. — PROFESSIONAL PDF EXPORT — Generate print-ready documents directly from your log data: - Ship's logbook (A4, fully formatted) - Customs declaration - Crew list for port entry - Ship dossier — COMPLETE VESSEL MANAGEMENT — KnotWise covers the full lifecycle of a passage — and everything between them: - Logbook & passage log — every voyage documented without gaps - Maintenance board — tasks, intervals and service history at a glance - Inventory & stowage plan — always know what's aboard and where - Crew management — crew members, documents and emergency contacts in one place - Offline vector charts — your track drawn automatically from log entries - 16 navigation calculators — tides, waypoints, fuel, provisions and more — OPTIONAL SYNC — Keep KnotWise in sync across your iPad, Mac and PC.

The Inventory is a list now Items appear as a list rather than tiles — grouped by area and compartment, sortable by name, quantity or expiry date and filterable by category. The same row carries the minimum quantity where you have set one, the expiry date in the format of your language, and whether the item is dutiable. Considerably more of your items fit on one screen. Headings stay put Scroll the Inventory and the area and compartment heading stays below the filter bar, so you still know where you are after a hundred items. In the logbook the passage and the column headings stay as well: you cannot read a row of course, SOG, Bft and hPa without them, and on a long passage that keeps both in view. Maintenance scrolls column by column The board fills the screen, and Planned, In Progress and Done scroll independently of one another. All three states stay side by side, the column heading holds still, and the target column stays put under your finger while you move a task. Your unfinished support message stays Close the window mid-sentence and your text is there when you come back. Also: on the chart you move straight from one log entry to the next, and the pop-up stays open. And a maintenance form you only looked at closes without asking.
