Trawler and Cruiser Surveys

A trawler is bought to go somewhere and live aboard while doing it, which makes the systems survey as consequential as the structural one. A boat that is structurally sound and has a failing genset is still a bad month.

Hull and Structure on Displacement Boats

Displacement hulls lead an easier structural life than planing boats. They do not pound, so the fatigue pattern is different and usually milder. What they do instead is sit, often for long periods, frequently in the same berth.

The inspection is the same one every boat gets. What a trawler produces is the things that come from sitting: boot stripe and waterline blistering, growth and corrosion patterns that indicate stray current in a marina, deck core around fittings that have been weeping quietly for years, and the condition of a hull that has not been hauled as often as it should have been.

On steel and aluminum hulls, which turn up more often in this category, plate condition and coating integrity move to the front of the inspection, particularly in the bilge and under tankage where you cannot see.

Engines, Gensets and Hours

Trawler diesels often show high hours and that is not the problem it appears to be. A well-maintained engine at continuous moderate load is in a far better place than a lightly used one that has spent its life idling and sitting.

What matters is maintenance evidence, cooling system condition, exhaust, mounts and the state of everything driven off the engine. Raw water systems get close attention because heat exchangers and aftercoolers on a boat like this are expensive and quietly deteriorating.

The generator gets inspected as seriously as the main engine. On a cruising boat it runs more hours than people expect and its failure ends the trip in a way an alternator problem does not.

Systems for Extended Cruising

This is what separates a trawler survey from a general one. Tankage capacity and condition, fuel polishing and filtration, the house battery bank and its charging arrangement, inverter installation, refrigeration, watermaker if fitted, heating, and the ground tackle and windlass.

Electrical distribution on a cruising boat is usually the most modified system aboard, because every owner added something. That is assessed against the ABYC standards rather than against whether it currently works, since plenty of non-compliant installations work fine until the day they do not.

Stabilisation, whether fins or gyro, and thrusters are inspected where fitted, along with their hydraulics.

Book a Trawler Survey

Call or email with the vessel, its location and whether you are buying for coastal use or something longer. That last answer changes what I spend time on. Your report is delivered the next day. Not next week.
