How can I tell if a used boat has been in an accident?
A used boat that has been in an accident may look fine at first glance, especially if it has been cleaned and repaired for sale, but there are usually clues if you know where to look. Start with a slow walk around the outside of the boat in good light, looking for areas where the paint or gelcoat does not quite match, where the finish looks thicker or rougher than the area around it, or where a repair has been blended in. Look for cracks that run in a straight line, chips along the edge of the hull, and dents or scrapes on the keel, the bow, and the rub rail.
Pay close attention to the structure underneath the finish, because a repair that looks neat on the surface can still hide weakness below. Press gently on the deck, the transom, and the sides of the hull, and notice whether any area feels soft, flexes more than the area around it, or sounds hollow when tapped. Check the transom for cracks around the engine mount. Look inside lockers and under floor panels for new fibreglass, fresh sealant, or mismatched materials, and check for water staining or dampness that could point to a crack that was not fully sealed. If the boat has a trailer, look for bent frames, damaged rollers, or a hull that does not sit evenly on its supports.
The engine and running gear can also show signs of an impact, even when the hull looks sound. Look at the propeller and the lower unit for bent blades, chips, cracks, or a new part fitted beside older, worn components. Check the steering for stiffness or play, and look for leaks around seals and joints that may have been disturbed. Inside the boat, check the dashboard, wiring, and fittings for loose panels, cracked mounts, or fresh screws that do not match the rest of the boat. Ask the seller directly about any accidents, groundings, or collisions, and ask for service records and repair invoices that explain any work you can see. A seller who is open and can show paperwork is far more reassuring than one who avoids the question.
Finally, take the boat for a sea trial and notice how it behaves under power. Watch for vibration, pulling to one side, difficulty holding a straight course, or a hull that feels uneven in a turn, because these can point to damage to the hull, the propeller, or the steering. Listen for new noises, and check for water coming into the bilge during the trial. If you have any doubt, arrange a professional marine survey before you buy, because a surveyor can spot structural damage and poor repairs that are easy to miss. If the history is unclear or the signs do not add up, walk away and keep looking for a boat with a clearer past.
