A boat tells you how it lived if you know how to listen.
1. The Bilge Line
Look at the high-water mark in the bilge. Is it oily? Is it 6 inches above the keel bolts? This boat has a history of flooding or pump failure.
2. Chafe Gear
Look at the chocks and cleats.
Heavy Wear on Starboard Cleats? The boat was likely docked starboard-to for years. Check the starboard rub rail and hull side for impact damage hidden by wax.
3. Sun Fading
Pull up a floorboard or a cushion. Is the varnish underneath dark and rich, while the exposed varnish is bleached? This tells you how much UV exposure the vessel has seen (e.g., Caribbean vs. New England).
4. Tool Marks
Look at the nuts on the engine. Are the corners rounded off? Are there plier marks?
Diagnosis: The owner used the wrong tools (Imperial vs Metric) or generic pliers. This indicates a lack of professional maintenance.
Conclusion
Wear patterns act as a truth serum for the seller's claims. "She was always stored indoors" is easily disproven by UV damage on the gelcoat.
