At eighteen metres the inboard installation is a plant room rather than an engine bay, and it is one of the most significant parts of the purchase. A yacht this size runs air conditioning, refrigeration, a watermaker and a substantial domestic load, and needs enough thrust to manoeuvre considerable displacement in a crosswind. The Yacht Collection lists eighteen metre inboard sailing yachts.
The specification reflects that. A main engine typically well over a hundred horsepower, one or often two generators, high output alternators, fuel in fixed tanks measured in thousands of litres with polishing and transfer systems, and bow and usually stern thrusters. The electrical architecture is a designed system with distribution, monitoring and redundancy.
Installation quality is what separates yachts at this length. Beds engineered into the structure, shafts running through thrust bearings, exhaust routed and silenced properly, acoustic insulation specified by frequency, and a machinery space a technician can genuinely work in. On a yacht serviced far from home, access is worth as much as condition. Survey accordingly and with specialists, covering engine and generator hours, oil analysis, heat exchangers and exhaust systems, shaft alignment records, stern gear at lift out, thrusters tested separately and the full electrical architecture assessed. Expect a maintenance programme rather than a service book. Browse the eighteen metre inboard sailing yachts available and speak to our brokers.
