Complete Yacht Survey Checklist Before Buying

A marine survey is the single most important step in buying a yacht. It can save you tens of thousands in hidden repairs — or confirm you're making a smart purchase.

What is a yacht survey?

A marine survey is a comprehensive inspection performed by a qualified marine surveyor before you complete the purchase of a yacht. The surveyor evaluates the vessel's condition, identifies defects, estimates repair costs, and provides a market valuation.

Who pays for the survey?

The buyer pays for the survey, typically $15-25 per foot of boat length. For a 50-foot yacht, expect to pay $750-1,250. This is non-refundable — even if you walk away from the purchase.

What the surveyor checks

**Hull and structure** - Hull integrity, blistering, osmosis damage - Keel attachment and condition - Rudder, propeller shaft alignment - Hull moisture readings

**Mechanical systems** - Engine compression and oil analysis - Transmission condition - Generator operation - Steering and throttle controls

**Electrical** - Battery condition and wiring - Shore power system safety - Navigation lights and electronics - Bilge pump operation

**Plumbing** - Through-hull fittings and seacocks - Freshwater and waste systems - Holding tank condition

**Safety equipment** - Life jackets, flares, fire extinguishers - Bilge alarms and smoke detectors - Emergency equipment

**Interior and cosmetic** - Headliner, upholstery, woodwork condition - Windows and hatches for leaks - Galley appliances

Sea trial — equally important

The survey usually includes a sea trial. The boat is taken out and tested under power. The surveyor checks engine performance at various RPM, steering response, vibration, and electronics function.

Reading the survey report

A typical survey report runs 20-40 pages. Look for:

• Recommendations marked as "required" vs "recommended"
• Estimated repair costs
• Fair market value compared to asking price
• Overall condition rating

What to do after the survey

If issues are found, you have three options: ask the seller to fix them, negotiate a price reduction, or walk away. A good buyer's broker handles these negotiations on your behalf.

How to find a qualified surveyor

Look for surveyors accredited by SAMS (Society of Accredited Marine Surveyors) or NAMS (National Association of Marine Surveyors). Both organisations require continuing education and adherence to professional standards.
