For professional mariners
Your sea time, logged and ready for MMC paperwork
Sea Service Log helps you track sea service days, vessels, and positions— so when you need testimonials or Coast Guard documentation, the numbers are already there.
Built for the way mariners actually work
Less spreadsheet chaos. More confidence when it’s time to renew or advance your MMC.
-
Log sea service days
Record days underway and on vessels with clear dates—no more reconstructing voyages from memory.
-
Vessels & positions
Keep vessel names, official numbers, and the positions you sailed so every entry stays audit-ready.
-
Summaries for testimonials & MMC
Generate clean totals and breakdowns that map to sea service forms and Coast Guard paperwork.
-
Export when you need it
Export your log later for applications, employers, or your own records—your data stays yours.
