Buying any boat is a big decision and is probably the second biggest personal outlay you will ever make. It's a major decision, and bluntly, when buying a used boat YOU'RE ON YOUR OWN.
Remember: "Buyer Beware".
"Caveat Emptor". The axiom or principle in commerce that the buyer alone is responsible for assessing the quality of a purchase before buying. When buying a used boat there are no warranties or guarantees. How do you know...
If there are problems your only recourse is pursuit of the vendor through the courts; which can be a long and costly procedure with unknown results.
Almost everyone you will deal with in choosing and selecting your boat will be working for the vendor. Brokers, advertisers, agents, agencies are all paid buy the vendor.
If you use a broker make sure they are professional, use a recognized form of contract (for example RYA/BMIF/ABYA if in the UK) and that your deposit is secure and returnable. In the United Kingdom, look for membership of the ABYA (the Professional Association of Yacht Brokers) and or the BMIF Boat Retailers/Brokers Scheme, which ensures a high ethical standard and established code of practice, correct paperwork and indemnity insurance.
You need a professional surveyor experienced in the type of boat you are considering.
A good surveyor will help and advise you on suitability and what to look for, he will play devils advocate in your decision purchase. He is your only guarantee and back up.
You need to have trust and confidence in your surveyor.
Surveyors can be found advertising in the yachting press; listed at the professional association's web sites, broker's “local or favourite” lists. Ask around in the yard, yacht club or marina or web forums for a personal recommendation.
Alarmingly there is no legislation, qualification or requisite standard to set up as a yacht surveyor. In the UK, look for a surveyor who is a fully accredited member of an established and tangible, professional body such as the YDSA, Yacht Designers and Surveyors Association, IMarEST, the Institute of Marine Science and Technology, MECAL, or the IIMS, the International Institute of Marine Surveyors (small craft section).
This ensures that the surveyor is fully accredited, scrutinized, and follows a recognized code of practice, but remember that an affiliate, student or technician grade member may have limited experience and knowledge of your type of vessel.
The Surveyor should be flexible to suit your needs or any special requirements and should explain and discuss the types and benefits of different surveys. The surveyor should be receptive to your enquiries, positive, helpful, willing and enthusiastic, never casual or dismissive.
Remember the Surveyor is working for you. It’s your Survey.
If at all possible attend the survey, after all it's your survey. Ask questions and talk to your surveyor, but don't stop him doing his job.
The surveyor should explain what he is looking at and why and what it means. This is invaluable when you need to understand and quantify a technical report.
Digest your report, make notes and discuss it with your surveyor. Ask questions. It is important to understand the findings and implications of the survey report and the advice of your surveyor. You will get more meaningful information from a frank discussion than a formal report.
If you are satisfied that you can make an informed decision, renegotiate, buy the boat, or pull out. Remember that your surveyor should still be willing and available for help or advice on an ongoing basis.
