What to look for when buying a boat

Every used boat is a collection of compromises. The question is not whether it is perfect — it is not — but whether you know what you are buying. A good viewing is part inspection, part detective work, and part honest conversation with the seller. These are the things that are easy to overlook but expensive to miss.

Your nose is the first survey tool

Step below and breathe in before you switch anything on. A boat should smell like wood, salt, fabric, and maybe a little diesel. It should not smell like a florist, a bathroom, or a cleaning crew that left five minutes ago.

Strong air fresheners, recently opened hatches, or the smell of bleach can hide mildew, holding-tank leaks, or a bilge that never quite dries. Lift cushions, open lockers, and sniff around the heads and shower sumps. Musty upholstery and damp plywood are not just unpleasant — they are a sign of trapped water somewhere it should not be.

Start the engines from cold

A warm engine when you arrive is a warning. A seller who has already run the engine may be hiding hard starting, rough idling, smoke on startup, or poor cold oil pressure.

Ask to see the engines start from cold. Listen for the starter labouring, watch the exhaust for excessive smoke, and feel how quickly the engine settles. It should fire promptly, idle smoothly, and pick up cleanly when you advance the throttle. Two engines? Start both, one at a time, and compare them.

Water in the wrong places

Some water is normal. Water in the bilge, in the engine pan, or staining the cabin headlining is not. Look under the engine, inside the bilge, and behind false panels in the heads and galley. Fresh stains on the floorboards, rust on engine mounts, or chalky residue around seacocks all point to a leak that has been going on for a while.

Tapping the deck and floorboards can reveal soft plywood or delamination. Soft spots near windows, hatches, and chainplates are common. They are fixable, but they should be priced in.

Ask for the service record

The service record is the difference between a known boat and a guessed one. Ask for engine service invoices, rigging surveys, anode changes, antifouling dates, safety gear service tags, and any major repairs.

A complete record shows the owner has been paying attention. A folder with a few receipts, or a vague claim that the boat was always maintained, usually means the opposite. If the boat has a digital service book, ask to see it. A history that is dated, costed, and linked to the actual engine is far more valuable than memory.

No boat is perfect — know what has been done

Do not look for a boat with no flaws. Look for a boat whose flaws you understand. Every used boat has a list of open items, and the honest seller will tell you theirs before you find them.

Make your own list of what needs doing now, what can wait, and what is just character. Use that list to negotiate, not just on price, but on how you will spend the first season. A boat that has been loved and documented will almost always cost less in the long run than a prettier one with no history.
