Why Do You Need This Checklist?

In my more than 30 years of international naval expertise, I have inspected more than 1,500 yachts in 40 countries. I have seen how Family Offices and investors lose millions of euros by not identifying critical defects during the inspection.

This checklist is the result of decades of experience. They are the50 points that you should NEVER overlookwhen inspecting a yacht, organized into 7 critical categories.

💡 Key Data

78% of second-hand yachts have at least 3 critical defects that are not detected in a superficial inspection. These defects can cost between €100,000 and €5,000,000 in repairs.

How to Use This Checklist

This checklist is designed to be used during the physical inspection of the yacht. I recommend:

  • Print the final version(pages 10-12) to take on board
  • Mark each pointas you inspect it
  • Take picturesof any anomaly
  • Document everythingin the notes section
  • Hire a certified expertfor a professional inspection

⚠️ Important Warning

This checklist is an educational guide. It does not replace professional inspection by a certified expert (SAMS, NAMS or IIMS). A professional inspection includes non-destructive testing, laboratory analysis and legally valid documentation.

01

Property Title and Registration

Verify that the property title is free of encumbrances, mortgages or embargoes. Check that the owner's name matches the official record.

02

Classification Certificate

Review the certificate from the classification society (Lloyd's, DNV, ABS, RINA). Verify that it is current and without pending conditions.

03

Maintenance History

Request the complete maintenance book. Verify that services have been performed according to the manufacturer's recommendations.

04

Claim History

Investigate whether the yacht has suffered accidents, fires, groundings or floods. Request reports of repairs carried out.

05

Statutory Certificates

Verify SOLAS, MARPOL, IAPP, IOPP, etc. certificates. Check that they are current and comply with international regulations.

06

Plans and Specifications

Request original shipyard plans (as-built). Verify that there are no unauthorized modifications to the plans.

07

Actual Engine Hours

Verify the operating hours of main engines and generators. Compare with maintenance history.

08

Insurance and Policies

Review current insurance policies (hull, machines, P&I). Check coverage, exclusions and claims history.

🔍 Expert Advice

If the seller cannot provide all the requested documentation, that is a red flag. A well-maintained yacht has complete and organized documentation.

09

Visual Hull Inspection

Examine the hull forcracks, deformations, dents or visible repairs. Pay special attention to the waterline.

10

Thickness Measurement

Perform hull thickness measurements with ultrasound. Compare with the original shipyard thicknesses.

11

Weld Inspection

On steel/aluminum yachts, inspect welds with penetrating dyes or magnetic particles. Look for microcracks.

12

Cathodic Protection System

Check the status of the sacrificial anodes or the ICCP system. Check that they work correctly.

13

Keel and daggerboards

Inspect the keel for damage, corrosion or repairs. Check the ballast system (if applicable).

14

Rudder and Steering System

Check the condition of the rudder, blades, hinges and steering system. Check for clearances and excessive play.

15

Propellers and Shafts

Inspect propellers for cavitation, damage or repairs. Check the condition of the axles and their seals.

16

Handrails and handrails

Check the solidity of handrails, railings and attachment points. Verify that they comply with safety regulations.

17

Hatches and Covers

Check the tightness of hatches, manhole covers and access to the hull. Check joints and closures.

18

Paint and Antifouling

Evaluate the condition of the paint system. Check the antifouling and the interval since the last application.

⚠️ Critical Point

The hull inspection must be carried out with the yacht out of the water (in a slipway). A superficial inspection from the water is NOT sufficient to detect structural defects.

19

Main Engines – Visual Inspection

Examine engines for oil, fuel or coolant leaks. Check the general condition and cleanliness.

20

Engine Oil Analysis

Take oil samples for laboratory analysis. Detect wear metals, fuel or water contamination.

21

Refrigeration system

Inspect heat exchangers, water pumps, thermostats and hoses. Check absence of corrosion.

22

Exhaust System

Examine manifolds, turbochargers, mufflers and exhaust pipes. Look for signs of corrosion or leaks.

23

Fuel System

Inspect tanks, pumps, filters and pipes. Check the absence of contaminants and water in the fuel.

24

Generators

Test generators under load. Check voltage, frequency, temperature and oil pressure.

25

Hydraulic System

Inspect hydraulic pumps, cylinders, hoses and connections. Check absence of leaks and correct pressure.

26

Air Conditioning System

Test air conditioning systems in all areas. Check compressors, evaporators and condensers.

27

Water System

Inspect water pumps, tanks, heaters and treatment systems. Check water pressure and quality.

28

Bilge System

Test bilge pumps (manual and automatic). Check water level in bilges and absence of leaks.

💰 Hidden Cost

Repair or replacement of a main engine can cost between €200,000 and €2,000,000 depending on the size of the yacht. A €300 oil analysis can detect problems before they become catastrophic.

29

Main Electrical Panels

Inspect electrical panels with infrared thermography. Detect hot spots, loose connections or overloads.

30

battery

Check condition, age and capacity of the batteries. Check connections and ventilation system.

31

Wiring and Connections

Inspect wiring for deterioration, loose connections or exposed wires. Check insulation.

32

Earth System

Measure resistance of the grounding system. Verify that it complies with safety regulations.

33

Protections and Circuit Breakers

Check that all circuits have adequate protections. Check circuit breaker calibration.

34

Lighting System

Test all lights (interior, exterior, navigation). Check operation of switches and dimmers.

35

Backup Power System

Test automatic transfer system between generator and network. Check UPS and emergency systems.

⚡ Fire Risk

35% of fires on yachts have electrical origin. A thermographic inspection can detect hot spots before they cause a fire. Inspection cost: €500-€1,500. Cost of a fire: €500,000 – €50,000,000.

36

Electronic Navigation System

Test radar, GPS, plotter, echo sounder, AIS and navigation systems. Verify calibration and operation.

37

Communication System

Test VHF, SSB, satellite (Inmarsat, Iridium) and GMDSS systems. Check DSC and EPIRB.

38

Security Equipment

Check life rafts, vests, lifebuoys, flares and safety equipment. Check expiration dates.

39

Fire Fighting System

Inspect fire extinguishers, fixed extinguishing system (CO2, water mist), smoke detectors and alarms.

40

Emergency Government System

Test emergency steering system (reserve rudder). Verify operation and accessibility.

41

Emergency Bilge System

Test emergency bilge pumps. Check flow and autonomy. Check manual operation.

42

Light and Acoustic Signals

Test navigation lights, signal lights and whistle. Verify that they comply with COLREG.

🛟 Safety First

Safety equipment expires. An expired life raft is not only illegal, it can cost you your life. Check all expiration dates before purchasing.

43

Interior Structure

Inspect bulkheads, fixed furniture and interior structure for movement, cracks or repairs.

44

Finishes and Carpentry

Evaluate quality of finishes, carpentry, upholstery and paint. Check general condition and maintenance.

45

Entertainment Systems

Test audio, video, TV, satellite and WiFi systems. Verify operation in all areas.

46

Kitchens and Service Areas

Inspect appliances, countertops, sinks and refrigeration systems. Check operation.

47

Bathrooms and Sanitary Systems

Test toilets, showers, sinks and sewage treatment systems. Check absence of leaks and odors.

✨ Luxury with Substance

Luxury finishes can hide structural defects. Don't be impressed by the aesthetics. A yacht can look perfect inside but have serious problems with the hull or systems.

48

Speed ​​and Consumption Test

Perform tests at different RPM regimes. Measure maximum speed, cruising speed and fuel consumption.

49

Maneuverability Test

Test turns, emergency stops, reversing and maneuvers in port. Evaluate response of the government system.

50

Testing Systems Under Load

Test all systems simultaneously under maximum load. Check temperatures, pressures and voltages.

🌊 The Ultimate Test

Sea trials are MANDATORY. Many defects only manifest themselves when the yacht is in motion: vibrations, noises, overheating, leaks. Never buy a yacht without complete sea trials.
