iVessel keeps every boat you run maintained, documented and ready to go — whether you look after one outboard or manage a whole fleet. LOG IT IN SECONDS - Engine hours in two taps with iVessel Lite — a simplified phone mode built for the dock, not the desk - Service and maintenance records for inboards, outboards, generators and every other machinery item on board - Pre-sail checklists so nothing gets skipped before you leave the berth STAY AHEAD OF MAINTENANCE - Service schedules tracked per machinery item, driven by real engine hours - Overdue and upcoming work surfaced automatically on your dashboard - Issues with photos — snap a problem, assign it, close it out RUN THE WHOLE FLEET - Fleet dashboard with exception views: see only the boats that need attention - Per-boat dashboards for owners and crew - My Work view for technicians: everything assigned to you, in one list - Invite crew, owners and technicians with role-based access EVERYTHING ELSE ON BOARD - Inventory with barcode scanning — scan a part, find it, restock it - Shore-side land store, with transfers on and off each boat - Manuals library shared across your boats - Trip logging with GPS position capture - Works on your phone, tablet and desktop — same account, same data, everywhere BUILT FOR REAL CREWS iVessel was built by people who run boats, replacing spreadsheets and paper logs with something the whole crew will actually use. Two-factor authentication and role-based permissions keep your fleet's data locked down. Add your boat, add its machinery, and start logging.
