Pre Purchase Vessel Surveys

Pre Purchase Boat Surveys

Buying a vessel is usually a significant purchase and slightly daunting, so you need to know the facts about the current condition of your potential purchase. 


The Pre Purchase Survey is conducted on behalf of the potential new owner and will usually be conducted once the price has been agreed upon and a deposit has been placed with the broker. This deposit will not usually be refundable unless there are any structural or serious defects found during the survey, which may end in the buyer either pulling out of the sale or as is more common, negotiating with the vendor for a proportion of the costs involved to have any defects rectified.


At Marine Sea Services, we will look over all aspects of the vessel and report on the condition, systems, and defects that are present. Our reports are in plain English and are often used to discuss prices with the broker, raise finance and obtain insurance.


Oil analysis
Oil samples can be taken and are sent for laboratory analysis to undertake an assessment of wear on the engine and indicate if water or diesel is present. This is a useful tool in the ongoing monitoring of a vessel's propulsion and power generation systems.
