Never lose a day of sea time
Free · In‑App Purchases
New: Bridgedeck on Apple Watch. Start voyages and log watches from your wrist — live watch timer on your dial, every entry synced to your logbook.
Bridgedeck Logbook is the sea-service logbook built for seafarers — a simple, reliable way to record your time at sea and keep it with you for your whole career.
Whether you're a cadet logging your first voyage or an experienced deck or engineer officer, Bridgedeck keeps your sea time, watches, voyages and certificates in one place — and it works completely offline, so you can log a watch mid-ocean with no signal.
LOG EVERY SEA DAY
• Record voyages, vessels, watches and ports in seconds
• Track days aboard on your active voyage in real time
• Works fully offline; syncs securely when you're back online
KNOW YOUR SEA TIME
• Automatic totals by gross tonnage (GT), power (kW) and rank
• Set your own sea-time targets and track your progress
• Monthly breakdowns of your time at sea
STAY CURRENT
• Keep every certificate in one place
• Get reminders before they expire — never get caught out
• Keep photos of your certificates in the vault (Pro) — stored on your device only, never uploaded
EXPORT YOUR SEA SERVICE
• Generate a Sea Service Testimonial in the MSN 1858 Annex E format straight from your logbook — ready to print and sign in ink
• A clean, professional PDF that's yours to keep and share
BUILT FOR SEAFARERS
• Free for your first 100 sea days — Bridgedeck Pro (annual) unlocks unlimited logging
• Your existing records are always free to view and export
• Deck and engine; merchant and yacht
• Your data stays yours — your logbook backs up privately to the cloud, and certificate photos never leave your device
Download Bridgedeck Logbook, log your next watch, and never lose a day of sea time.
