Breakdown Inspection of Material during Yacht repair Inspection.
There are different types of materials used in structures and how structures are put together to resist the forces. All of the above has been based on the supposition that the materials remain and function in accordance with their normal properties. However, in practice all materials are subject to degradation over time from a variety of different sources. some examples of materials used for yachts noted in their several years of experience by constellation marine inspectors are as under:-

Timber that has been well seasoned and that is kept in a uniform state of moisture (neither too wet nor too dry) when properly ventilated will remain stable and with no significant degradation for many hundreds of years. However, as a naturally occurring material, wood has naturally occurring enemies which come in the form of fungus (mould), worms and beetles which need to be inspected carefully.
Common Rot noticed by constellation marine surveyors during detailed Yacht/Boat condition inspection and surveys.
This is manifested by the presence of external yellow spots on the ends of the timber and is often accompanied by yellowish dust especially where the pieces of timber are in contact. The main cause is poor ventilation of the timber.
What is Wet Rot and how significant is it to be noticed during Yacht repair inspection?
Moisture, especially in the presence of warmth, will dissolve out some of the constituents of the cell walls and thereby cause decay. However, timber kept constantly immersed in water may soften but does not, in general, decay. It is the cyclical nature of wetting and drying that does the damage.
