Description by Lucas MARCHE(from the App Store)
MyVessel is the logbook for merchant navy officers and cadets. Embarkations, sea time, STCW certificates, renewals: your whole career in one place.
IMPORT FROM THE FRENCH SEAFARERS' PORTAL • Service record: your service lines become embarkations, grouped by ship, with tonnage and ship type filled in from the French-flag ship register. • Seafarer record: certificates, STCW endorsements and medical fitness, sorted by expiry. • Nothing is written without your approval, and every import can be undone.
YOUR SEA TIME • Counted under the French rule of 10 August 2015: a month is 30 days. • Ongoing embarkation, overlaps flagged, leave lines left out.
YOUR STCW CERTIFICATES • Progress towards your next certificate: officer of the watch, chief mate, master, chief engineer. Deck, engine or dual-purpose track. • Simulator: how many sea days until your next certificate?
YOUR CERTIFICATES AND THEIR EXPIRY DATES • Reminders 90, 30 and 7 days before each expiry, in time to book the course. • The notification never names the certificate: nothing sensitive on the lock screen.
YOUR CAREER ON A 3D GLOBE • Passages drawn along real shipping routes, with port calls and waypoints: Suez, Panama, Cape Horn… • Countries, ports, distance sailed, notable passages.
DISCHARGE BOOK AS PDF • A clean record of your embarkations, ready to attach to an application.
100% PRIVATE No account, no server, no data collected. Everything stays on your iPhone, and backups go to the folder of your choice, including iCloud Drive.
MyVessel is not an official maritime administration app. Calculations are for guidance only: the certificate-issuing authorities have the final word.

the same time period. Subscriptions can be cancelled at any time before the renewal.
