Yacht inspections are often seen as “formal requirements”. In reality, they are something far more important: the only reliable way for an owner to understand the true condition of their vessel, prevent failures and avoid unexpected expenses during the season.
And here lies one of the biggest misconceptions in the Greek yachting market:
Commercial yachts are required to undergo Class, Flag and Insurance inspections. Private yachts are not — but that doesn’t mean they don’t need them.
In practice, most costly issues come from private yachts precisely because no inspection is required.
For owners, this translates into risk, reduced value, safety concerns and technical failures that could have been prevented with a simple seasonal check. This guide was created to give you a clear, structured and honest overview: What types of inspections exist, what each one includes, and how to prepare your yacht properly, whether it is small or large, private or commercial.
Commercial Yachts: What Class, Flag & Insurance Surveys Actually Look For
Commercial vessels follow a strict framework of mandatory inspections.
Class Surveys
Performed by classification societies, covering:
- machinery & generators
- structural integrity
- safety equipment
- navigation systems
- operational systems
- documentation
- follow-up on previous remarks
Flag State Inspections
Ensuring the vessel complies with the requirements of the flag:
- certificates
- operational readiness
- safety equipment
- conformity in areas such as ISM / ISPS / MLC (where applicable)
Insurance Surveys
Insurers require surveys to verify whether the yacht meets safety and condition standards.
Minor observations can increase insurance premiums.
Commercial inspections are demanding, but at least they follow predictable rules.
Private Yachts: Why Preventive Inspections Are Essential (Even If Not Mandatory)
Most private yachts, especially smaller ones, never undergo a technical inspection. This is where the majority of problems originate.
Without a seasonal technical assessment:
- the condition of engines and systems is unknown
- safety equipment may not operate correctly
- electrical issues go unnoticed
- no structured technical file is kept
- minor findings turn into expensive failures
Small private yachts (RIBs, day boats, 25–40ft motor yachts) are statistically the most exposed, because owners assume “everything is fine”, until something breaks.
Preventive inspections offer:
- lower long-term maintenance costs
- early detection of hidden issues
- safer operation for family and guests
- higher resale value
- better performance at sea
- peace of mind before the season begins
For a private owner, a yearly or semi-annual inspection is not a luxury, it is the only way to truly know the condition of the yacht.
The Four Types of Yacht Inspections Every Owner Should Know
1. Preventive Technical Inspection (Private Yachts)
A full assessment covering:
- engines, generators, pumps
- electrical systems
- navigation & deck equipment
- fuel, bilge & fluid condition
- safety equipment
- documentation & technical file
The purpose is simple; to know the condition of your vessel before you go to sea.
2. Class / Flag Surveys (Commercial Yachts)
The mandatory inspections defined by international regulations.
3. Insurance Surveys (All Yachts)
Required by insurers, especially for higher-value yachts.
4. Pre-Purchase Surveys
The most important inspection before buying any yacht. Evaluates hull condition, mechanical systems, sea trial performance and documentation.
What a Proper Yacht Inspection Should Include
Documentation & Certificates
- expiry dates
- manuals and logs
- records of previous works
- operational history
Safety Equipment
- life-saving appliances
- fire-fighting systems
- radio equipment (VHF/EPIRB)
- readiness in case of emergency
Machinery & Technical Condition
- main engines
- generators
- electrical panels
- bilge & fire systems
- pumps and valves
Structural & System Review
- watertight integrity
- deck fittings
- navigation systems
- hotel/comfort systems
Sea Trial (When Required)
Verifies the real operational behavior of the yacht.
What Happens When a Yacht Is Not Inspected
- sudden mechanical failures
- electrical breakdowns
- leaks and corrosion issues
- expired or non-functional safety equipment
- high fuel consumption
- lower resale value
- costly last-minute technical work
- negative findings on future surveys
Most of these issues are preventable with a simple, structured seasonal check.
Frequently Asked Questions
1. Do small private yachts really need inspections?
Yes. It is the only way to know their actual condition before the season.
2. How often should a yacht be inspected?
Once a year, or before seasonal operation.
3. What is the difference between private and commercial inspections?
Commercial yachts undergo mandatory Class/Flag surveys.
Private yachts do not — which is why preventive checks are essential.
4. Does an inspection improve resale value?
Absolutely. A yacht with documented technical oversight retains higher value.
