Why Spring Commissioning Matters
After months of storage, your yacht faces unique challenges such as moisture buildup, corrosion, and wear caused by inactivity. Proper commissioning prevents mechanical failures, preserves equipment life, and ensures your vessel is safe for operation. Skipping or rushing this process risks costly repairs during peak season.
Key Spring Commissioning Tasks
- Engine Startup and Inspection
Check oil and coolant levels, replace filters if needed, inspect belts and hoses for cracks or swelling. Flush antifreeze from cooling systems, inspect raw water strainers, and verify fuel system integrity, including filters and water separators. Conduct a careful first start, monitoring oil pressure, temperature, and bilge function. - Electrical Systems Check
Test battery voltage and load capacity; clean and protect terminals against corrosion. Verify shore power connections, bilge pumps (auto and manual), navigation lights, and safety alarms (carbon monoxide, smoke detectors). - Hull and Running Gear Inspection
Clean and inspect the hull for blisters, cracks, or damage. Check through-hulls and seacocks for proper operation and security. Inspect propellers and zinc anodes; replace zincs as needed. - Fresh Water and Sanitation Systems
Flush freshwater lines to remove antifreeze and sanitize. Inspect plumbing, water heaters, and heads for leaks and operational integrity. - Safety Equipment Verification
Inspect all fire extinguishers, flares, life jackets, EPIRBs, and personal flotation devices (PFDs) for condition and regulatory compliance. Replace expired items.
Timing and Climate Considerations
Complete commissioning 4-6 weeks before your intended launch for temperate regions, earlier if you live in colder climates. This schedule allows time to order parts, correct issues, and have professionals assist if necessary.

Frequently Asked Questions
How early should I start spring commissioning?
Start 4 to 6 weeks before launching to allow time for parts and repairs.
Can I reuse antifreeze in freshwater systems?
No, always flush and sanitize with fresh water before use.
How often should I change my impeller?
Typically every 300 engine hours or every 2 years, whichever comes first.
What should I do if I find water in my fuel?
Drain the fuel tank or use water-separating filters. Get professional help if contamination persists.
Is professional help necessary for spring commissioning?
Basic tasks can be DIY, but complex engine or electrical work is best left to professionals.
Following this spring commissioning checklist ensures your yacht is ready for safe, reliable cruising and protects your investment year-round.
