Tax, sea time and certificates — in your pocket
You care about protecting your income, not losing sea time, and never getting caught out with an expired ticket. SeaLog keeps the record for all three, offline-first, without needing a managed vessel to get started.
What actually costs seafarers money
Losing your SED claim to a messy day-count. An expired ticket you didn't see coming. Not knowing when you're actually back onboard.
SED Tax Tracker
The Seafarers' Earnings Deduction can exempt your foreign earnings from UK tax entirely — but only if the day-count holds up. SeaLog follows HMRC Helpsheet HS205's eligible-period method so you're keeping the right record from day one, not reconstructing it under a January deadline.
- 365-day qualifying period and 183-day single-visit limit, tracked automatically
- Departure/return "midnight rule" and foreign-port-call checks applied to every trip
- "Import from rotation" turns your onboard schedule into reviewable trips in one tap
- Exports as a supporting record to keep with your Self Assessment — for record-keeping and estimation, not a substitute for your accountant
Certificate Tracker
Every certificate you hold, with a plain colour-coded countdown to expiry — and when one's coming due, SeaLog points you straight at the right renewal route instead of you having to work out where to even start.
- Colour-coded expiry status across ENG1, STCW, CoC and every other certificate on file
- Each expiring certificate matched to a renewal route — official MCA workflow, training refresher, or approved doctor — with real provider contacts
- Your documents stay on your device; upload once and they're there for every renewal
Crew Card & Roster
Set up your own crew card in minutes — no managed vessel required — or scan onto one if your admin's issued a QR code. Either way, your rotation and onboard/off status stay current without you doing the maths yourself.
- Solo self-created card if you're not tied to a managed vessel
- Scan an admin-issued QR to link your device and sync your record to the ship's office
- Live onboard/off status and days-until-next-change, always visible on your dashboard
Exam Tracker
A countdown to your next MCA exam, linked straight to the official reference material for it — no digging through gov.uk to find the right syllabus or exam-date timetable yourself.
- Set up any Deck, Engine or Engineering Small Vessel exam, oral or written — written entries follow the real MIN 710 paper structure
- The Syllabus card links to the exact official MCA document for the exam you're tracking, scoped to your department and exam type
- MIN 710 exam-date timetable and, for oral exams, an Exam Day Prep checklist for the online format
