About

CaptainsDeck

Features
Read full description

CaptainsDeck brings your boat's entire operation into one app: pre-departure checks, issue tracking, tank and fuel management, engine-hour based maintenance and a digital logbook. A CHECKLIST BUILT FOR YOUR BOAT - 74 brands, 1000+ models. Model-specific items (IPS pod check, shaft seal, saildrive bellows…) are included automatically. - Boat not listed? Add your own: pick propulsion and equipment, and the checklist is generated for your boat. - Edit technical values (tanks, cabins, seacocks) to match your boat; count targets and liter math update instantly. ISSUES AND NOTES - Photo-based issue logs; compare two photos side by side or as an overlay to track changes (perfect for bilge monitoring). TANKS AND COSTS - Fuel, water, grey/black levels; receipt-photo fuel logs; monthly and yearly fuel cost summary. Liters/gallons and currency options. MAINTENANCE AND REMINDERS - Engine-hour counter, rules like "oil every 100 hrs" with color countdowns, and dated reminders (flare expiry, raft service) with notifications. LOGBOOK AND REPORTS - Trips with departure/arrival, route, crew and engine hours; ending a trip updates the maintenance counter automatically. - Export the checklist as a signed PDF report for marinas, insurers or charter handovers. CREW SHARING - One share code keeps your captain and crew on the same boat: checks, issues, tank logs and trips sync across devices. Joining requires the owner's approval; access can be revoked anytime. Works fully offline — no internet needed at sea. No account required; your data stays on your device. Note: Catalog values are approximations derived from class typicals and can be edited in-app. CaptainsDeck is an aid and does not replace official maritime regulations or manufacturer instructions.
