Out offshore, the sea’s honest about what it can do, and the boat’s just as honest—you simply don’t always hear it the first time. Most breakdowns don’t arrive as a bang; they arrive as a small change you meant to remember, then forgot somewhere between watches and landfalls.
A maintenance log is how you keep your future self from guessing. A few steady notes, taken the same way every time, will show you what’s drifting, what’s holding, and what’s due—especially when the days blur and the engine hours don’t.
Think of it as leaving good seamarks for the next run: clear enough that anyone aboard can pick it up and know what was done, what it looked like, and what you’d want checked again before you shove off.
