About Bosun's Mate
Bosun's Mate is the quiet, beautiful captain's log every boat owner deserves. Whether you have one boat or a fleet, Bosun's Mate keeps every receipt, every oil change, every fuel fill-up, and every cruise in one place — and across every device you own.
MULTI-VESSEL MANAGEMENT
Powerboat, sailboat, or commercial fishing — each vessel gets its own log with the right categories pre-loaded. Switch between boats in a tap.
MAINTENANCE THAT KNOWS WHAT'S OVERDUE
Schedule service by engine hours, calendar date, or seasons. Bosun's Mate watches the clock and tells you what needs attention.
FUEL & ENGINE HOURS, BEAUTIFULLY
Track fill-ups, engine hours, and your MPG sweet spot across RPM ranges. Plan trips with confidence — know exactly how far you can go on a tank.
CRUISING LOG
Capture every trip: departure and return dates, hours underway, distance in nautical miles, anchorages visited, and photos. Average speed is computed automatically. Your seasons, captured.
AI RECEIPT SCANNING
Snap a receipt with your phone camera. Our AI reads the vendor, amount, and date for you. Multi-photo entries supported.
