Boatie Logbook

Boatie Logbook is a sailing logbook built for real passages.
Start the log when you slip lines, capture weather and position at each watch change, review the track afterwards, and export a clean PDF for the boat's paperwork, insurance, or certification.

Designed offline-first. Core logging works without an internet signal — because that's what cruising is actually like. Every new download includes a 10-day preview before you choose a plan.

— BASIC (one-time purchase) —
• Passages with departure / destination, crew, vessel, and timed log entries

• Crew building miles on deliveries and club cruises

Your log data is yours. Photos and dictation never leave the device. Track data syncs via your iCloud account (not my servers) unless you export it. I don't sell data or run ads.
