SURVEYS

Pre-purchase and insurance surveys include inspection of all normally accessible parts of the boat.

The vessel is normally required to be lifted or dried out to gain access to the outside of the hull, keel, stern gear etc. The structural part of the survey will differ with the hull material, but the internal structure and systems, such as gas and electrics, are carried out in a similar manner whatever the construction method.

Fuel, gas and electrical systems have the potential to be a significant safety issue, and all accessible parts are given a thorough inspection.

GRP/FRP

The usual question asked by a purchaser when inspecting the underwater sections of a hull is "Has it got osmosis?" Quite often the answer is 'yes', but the degree of blistering and moisture content of the hull will vary considerably within this simple answer. Minor wicking and raised moisture content in a thirty year old hull costing £12,000 will be seen differently to a two year old boat costing £200,000.

Any faults found with any hull will be reported, but the significance of the fault will also be discussed with the client, to ensure that they have as complete a perspective of the situation as possible.

TIMBER

Timber hulls come in a variety of forms, which pose different potential problems. Visual inspection is always the first method of assessing condition, with a moisture meter and careful light hammer sounding being used where appropriate. Spikes are used only where necessary, to prevent damage to painted or varnished surfaces.

Always aware that a wooden boat, particularly an old wooden boat, is seldom in perfect condition, so attention is given in the report as to the seriousness of the faults found. Structural problems are given prominence, but also advice on the need for preventative maintenance will be given.

Experience gained from building and repairing many types of timber boats ensures that a wooden hulls strengths and weaknesses are understood, and the most appropriate method of repair can be recommended.

STEEL

Steel and aluminium hulls are inspected using ultra-sonic thickness testing, as well as visual and, where appropriate, hammer sounding.

A number of ultra-sonic readings are taken around the hull at regular intervals, and the results presented in a table describing the location and thickness of the metal found. Suspect areas are also measured and reported on. As with other hull materials, the internal structure and stiffening is also inspected wherever access can be gained.
