A pre-purchase marine survey is a detailed inspection and evaluation of a boat or yacht performed before you buy it. It is similar to a home inspection when purchasing a house and is considered one of the most important steps in buying a used vessel.

Purpose of a Pre-Purchase Marine Survey
The survey helps a buyer:

• Determine the vessel’s overall condition
• Identify existing defects, damage, or safety issues
• Estimate the cost of repairs and maintenance
• Verify that major systems are functioning properly
• Confirm whether the boat is worth the asking price
• Provide information that lenders and insurance companies may require

Why Buyers Get One
A pre-purchase survey can uncover expensive problems that are not obvious during a casual viewing. Issues such as hidden moisture in the hull, structural damage, electrical hazards, or engine problems can cost thousands of dollars to repair. The survey gives buyers objective information to negotiate the price, request repairs, or decide not to proceed with the purchase.

For most used boats—especially larger vessels—a pre-purchase marine survey is considered money well spent because it can prevent costly surprises after the sale.
