Unit 23. Inspecting Yacht & Small Craft Engines


The survey may be pre-purchase, insurance, valuation, damage or repair. There are surveyors who restrict themselves to either hull or machinery, however clients generally expect their surveyor to cover both disciplines. The surveyor will be expected to comment on the condition of the vessel. He should also be able to advise on the current condition of the machinery and systems, and to comment on their practicality or deficiencies.

The report must of course bring to the attention of the instructing client any defects found but also problems that the surveyor considers may arise in service. It can be a daunting task to climb aboard a strange vessel and attempt to find all the systems and their components, to get them working, and to discover any problems.

This surveying module is based on non-destructive examination, only portable structure is removed for access, the surveyor does not dismantle equipment or carry out internal examinations of engines, tanks etc. unless specifically agreed. The surveyor has to rely on external evidence to draw conclusions as to the internal condition and operational ability of a piece of equipment.

There will be occasions where specialist engineers (approved by, or representing the manufacturer) will be appointed to dismantle a particular piece of equipment, such as an engine. Their analysis can be added to the surveyor’s report, and the surveyor will comment on the significance of the specialists report. Accordingly, the surveyor examines a piece of equipment for general appearance and paintwork condition. Usually, a replacement item will not be painted to the same shade of colour, which may be immediately apparent. The gaskets of the connecting flange and associated bolts and nuts may show evidence of removal and replacement.

With a motor yacht the most important issue is the serviceability and performance of the engine, or engines. A sea trial should always be recommended as part of the survey process for a motor powered vessel. This is less important for a sailing vessel with a small auxiliary engine.
