You can cross an ocean with a lot of small annoyances, but a new vibration isn’t one of them. The boat’s telling you something, usually before it gets expensive. At the helm you feel it first: a buzz in the wheel, a shudder in the sole, a change in the engine note that doesn’t belong.
The trick is to stay calm and get methodical. Make a few deliberate changes, one at a time, and pay attention to what shifts. Most of the time you don’t need heroics—just a notebook, a cautious hand on the throttle, and the good sense to stop chasing ghosts when the evidence points elsewhere.
