Track your sea time automatically, and walk into your CoC application with the testimonials your verifier expects. SeaTime Tracker is built for yacht crew, commercial crews and merchant officers working towards OOW, Master and other CoC qualifications. Add your vessel and we log your days at sea from real AIS data, then produce signature-ready PDF testimonials laid out for MCA, PYA and Nautilus verification. Automatic tracking needs your vessel to transmit AIS. No AIS on board? You can log your sea time manually instead. WHY CREW CHOOSE SEATIME TRACKER β€’ Automatic sea time: pick the vessel and we fill in the dates from its AIS movements β€’ Import past sea time: add passages from your vessel's AIS history for the periods you were aboard before you joined the app (free check first, one-off purchase) β€’ Your progress at a glance: confirmed sea days on Home, matching the report you submit β€’ Testimonial PDFs laid out for PYA, Nautilus and MCA sign-off β€’ Sign in the app: add your signature, then send the PDF to the master to stamp and sign β€’ MCA and USCG pathways, each counted the way that authority counts a sea day, including every MCA yacht ticket from Yacht Rating to Master (Yachts) Unlimited β€’ Commercial crews: clock in and out of a shift so only the hours you worked count β€’ Rotational crew: switch Off board when you go on leave and tracking pauses until you're back β€’ Every service type: watchkeeping, standby, yard and service in port β€’ Night watch hours, trade area and rank recorded on every entry β€’ Certificate expiry reminders at 90, 60, 30 and 7 days β€’ iPhone, iPad and Mac BUILT FOR THE TICKETS YOU'RE WORKING TOWARDS Whether you're a deckhand building time towards OOW (Yachts), a watchkeeper going for Chief Mate or Master 3000gt, a US mariner working towards a USCG credential, or a cadet logging sea phases, SeaTime captures what the verifiers ask for: dates, vessel, tonnage, role, watchkeeping hours, trade area and master sign-off. NEVER LOSE A DAY OF SEA TIME Paper logbooks get lost. Spreadsheets break. SeaTime Tracker backs up every entry to your account, so when you apply your whole history exports in seconds, already laid out. CERTIFICATES THAT WON'T CATCH YOU OUT Keep track of every ticket, medical, visa and STCW course. Reminders arrive well before each expiry date, so your next contract never slips on a lapsed ENG1. For your privacy the app keeps only the details and dates, never a copy of the certificate. ABOUT FORELAND MARINE SeaTime Tracker is made by Foreland Marine, a UK consultancy run by working mariners.
