Keel Care and Inspection.
Every keel depends on regular maintenance to remain structurally sound. Inadequate inspection schedules allow;
- corrosion to progress internally
- fasteners to work loose
- seals bolts and washers to deteriorate without detection
A proactive maintenance regime identifies these issues before they compromise the hull-to-keel interface.
Key maintenance tasks include:
- Visual inspection of hull-keel joints and keel-bolt access points at every haul-out
- Torque verification of keel studs against naval-architect or manufacturer specifications
- Scheduled non-destructive testing (ultrasonic thickness, dye-penetrant, radiography) every 3–5 years
- Immediate haul-out and inspection following any grounding event
- Maintaining a detailed service log of haul-out dates, torque readings, NDT results, and repairs supports transparent risk management.
- Comprehensive records enable accurate survey assessments, inform prospective buyers, and help extend the operational life of the keel system.
