Marine Engineer
Marine Engineer is the broad title captains and agents use when they want a qualified engineer who can hold a watch and fix things without supervision. You keep the main engines, generators, water makers and air conditioning running. You also keep the paperwork straight. Plenty of yachts hire from the merchant fleet, the navy and commercial workboats, so this is a common way in.
The jobWhat fills the day
The work covers everything below the waterline and behind the panels. You check the main engines and generators daily, take readings, change filters and oil, and service the water makers, sewage plant, stabilisers and HVAC. You track fuel, lube oil and bunkering, and record every job in the planned maintenance system. When a guest cabin goes warm at midnight or a toilet blocks, someone calls you. A good engineer fixes it quietly, logs what happened and orders the part before it fails again.
Size changes the job. On a 35m yacht you may be the only engineer, which means you also drive the tender, help on deck and talk to contractors yourself. From 60m you sit inside a department with a chief, an ETO and possibly a third engineer, and you work to a watch rota. With guests aboard, noise, smell and comfort come first. Generator swaps, tank transfers and noisy jobs happen early or wait for a quiet hour. Shipyard periods mean long days with contractors, permits and class surveyors.
Captains hire on certificates and on hands-on proof. A merchant navy officer with a STCW III/1 ticket, a former naval artificer or a commercial diesel mechanic with an AEC and Y4 can all get interviews. What separates candidates is working experience with MTU, CAT or MAN engines, and with yacht systems such as Naiad stabilisers, Heinen and Hopman air conditioning and Sea Recovery water makers. A tidy engine room, clear logs and a calm manner with the interior team count for a lot.
Progression follows the MCA yacht ladder. Engineers with Y4 move to Y3, then Y2 and Y1, adding sea time and college modules at Warsash, Southampton or Glasgow. Those holding merchant tickets can cross to the large yacht fleet at 3000gt and above, where unlimited CoCs carry more weight. Most marine engineers reach second engineer within two or three years and chief engineer on a 40-60m yacht by year eight. Some later move ashore into technical management or refit supervision.
Skills captains look for
- Diesel engine maintenance
- Generator and switchboard work
- HVAC and refrigeration
- Planned maintenance systems
- Fault finding under pressure
- Bunkering and fuel management
- Contractor and yard liaison
A day aboardOwner trip, 62m motor yacht, at anchor off Bonifacio, Corsica
Engine room rounds before guests wake. Readings on both generators, check bilges, water maker output and fuel day tank levels.
Breakfast in the crew mess and a quick handover with the chief engineer on overnight alarms.
Change fuel filters on the standby generator and log the hours in the PMS. Order spares for the next service.
Guest cabin reports a noisy air conditioning unit. Find a loose fan mount, fix it while the guests are on the beach club.
Lunch and an hour off in the cabin.
Help the deck team with a jet ski that won't start, then flush and check the tender's outboards.
Transfer fuel between tanks to keep the yacht trimmed, and check the sewage plant ahead of a full dinner service.
Evening rounds, then watch the alarm panel during dinner in case the galley loads trip anything.
Hand over to the duty engineer and finish for the night.
Pay by yacht sizeMonthly, before tips. Estimates. Bars share one scale.
Rotation of 2:2 or 3:1 is common from 50m, often with slightly lower pay than a permanent post in exchange for the time off. Charter yachts add tips, usually split evenly across the crew. See the Engineer salary guide for figures from live adverts.

Questions crew ask
Can I move from the merchant navy to yachts as a marine engineer?
Yes, and many do. An STCW III/1 or higher certificate is recognised, and on yachts over 3000gt it is often preferred. You will need to learn yacht systems and get used to working near guests, which takes a season or two.
Is a marine engineer the same as a second engineer?
Not exactly. Marine Engineer is a general advert title that can mean a sole engineer on a 35m yacht or a watchkeeping engineer on a 70m. Read the advert for the yacht size and the certificate asked for to judge the level.
Which certificate should I aim for first?
Most yacht engineers start with the AEC and then the MCA Y4, which lets you work as a second engineer on smaller yachts and build sea time towards Y3. Merchant cadets follow the OOW engineering route instead.
Where do engineers find work?
Antibes, Palma and Fort Lauderdale are the main hiring centres. Shipyard periods in winter, in places like La Ciotat, Barcelona and the Netherlands, also create relief and permanent openings.
