A hull condition survey includes checking the structural condition of the vessel by using ultrasonic testing equipment, hammer testing, and by assessing pit depths, corrosion, and initial build quality. The inspection also checks the stern gear, weed hatch, and freeboard and normally takes half a day.
I would always recommend having a hull survey carried out as a bare minimum when buying a narrowboat to protect your investment, as a £300 survey is much easier on the wallet than a £10,000 full over plate!
When the survey is complete I will phone you and give a verbal summary of what I have found, then provide the written report by email and post with 3 working days (normally 48 hours)
