The above are a snapshot of professional marine surveyors which may be approached to survey a prospective purchase or insurance settlement. Choosing an approved surveyor is a good idea as non-professionals will advertise their services and may prove inferior.
Most finance and boat loan companies will insist on a survey before funds are released and this may also apply to some insurance companies depending on the age and the value of the vessel.
Marine surveyors offer their specialist knowledge and provide a written report on the general condition of the boat or yacht, recommend repairs to any current or potential defects. This can be reassuring if you have seen a craft you are planning to buy for leisure or for business/commercial purposes.
Just like buying a house, a mortgage on a house boat will almost certainly require a marine surveyors report on its condition and its loan to value from a company belonging to an accredited organisation.
