Third Engineer

The Third Engineer is a hands-on member of a three to six person engine department on a larger yacht. You work through the planned maintenance system, changing filters, servicing pumps, checking separators and logging running hours. When something breaks, from a guest cabin air conditioning unit to a seized watermaker valve, you are often the first engineer on the job. The Chief sets priorities and the Second runs the daily plan, but much of the actual spanner work is yours.

You stand engine room rounds and watches, both at anchor and underway. That means walking the spaces every few hours, reading gauges, checking for leaks, monitoring generators and noting anything unusual in the log. Overnight you may be on call for alarms. You also look after black and grey water systems, fuel transfers, bunkering checks and the sewage plant. It is not glamorous work, but a yacht cannot host guests without it, and good captains notice who keeps it tidy.

Tenders and water toys often fall to the Third Engineer too. Before guests come aboard you check outboards, jet ski engines and seabob batteries so the deck team can launch without delay. You help with refits and yard periods, working alongside contractors and learning systems in depth. Most Third Engineers hold AEC and MEOL and are building sea time towards Y4. The role is where you turn a trade background into real yacht engineering experience and prove you can be trusted with more.
