Marine Logbook: Boat & Sail

Your boat's entire life. One logbook.

Marine Logbook is the complete record of everything that happens aboard — voyages, fuel, maintenance, expenses, marina stays, inventory and more. Built for sail and power, it replaces your paper logbook and scattered spreadsheets with one beautifully simple app you'll actually keep. No account required, works fully offline, and your records are never locked in.

Why Boat Owners Choose Marine Logbook Log a voyage in seconds Departure and arrival, distance, speed, crew, engine hours and sailing mode — capture a full passage in a few taps. Add notes, photos and sea conditions while they're still fresh. Everything works fully offline, so you can log from the helm, mid-passage, anywhere at sea.

Your boat's complete service history Record every service with what was done, when, and what it cost. Track engine hours across entries and keep the full picture of your boat's condition. A complete maintenance history pays you back at resale — hand the next owner or your surveyor a clean PDF service record instead of a shoebox of receipts.

Smart reminders Set a due date and get notified before it arrives — on the day, days ahead, or at the exact date and time you choose. Engine service, safety equipment expiry, document renewals: nothing slips through.

Know what your boat really costs A dedicated fuel log with volume and cost. Expense tracking by category. Marina stays and berthing fees. See where the money goes — in your currency and your units, metric or imperial.

Purpose-Built Categories - Voyage - Fuel - Maintenance - Expense - Inventory - Weather & Sea - Marina - To-Do

No generic note fields. Every category has fields designed for exactly that job, so logging is fast and your records stay consistent.

Photos and documents, attached Attach photos and files to any entry — receipts, survey reports, engine plates, harbor documents. Everything stays with the record it belongs to, backed up together.

Find anything fast Search your entire logbook and filter by category in one tap. That impeller change from two seasons ago? Found in seconds.

Reports That Prove It One-tap PDF logbook reports and CSV export for spreadsheets. Ideal for insurance claims, charter licensing, warranty questions and resale. Your logbook, ready to hand over.

Private by Design No account, no sign-up, no tracking. Your logbook lives on your device and backs up automatically to your personal iCloud. Export everything anytime — your data belongs to you, forever.
