Aluminium Boat Survey

Aluminium Boat Survey

For an aluminium boat survey, the hull thickness is measured with an ultrasonic gauge that reads through paint. Yacht hulls and decks are also visually examined for cracks and weld quality.

Marine aluminum alloys are excellent materials. An aluminium yacht from a reputable builder should have a long life. Aluminium is both light and tough (although not as tough as steel). Because it forms its own protective coating, the hull topsides and deck are sometimes left unpainted. That gives a considerable saving in the maintenance costs. However, aluminium is vulnerable to corrosion if left in contact with different metals. It will also corrode if a defective electrical system allows current to pass through it. Those matters need to be carefully considered when surveying aluminium yachts.

Otherwise, the fittings and equipment are surveyed as for fibreglass (GRP) yachts.
