Third Engineer

Day to day the work is hands-on. You start with engine room rounds, logging pressures, temperatures and running hours on the main engines, generators, watermakers and sewage plant. Then you work through the planned maintenance system: filter changes, impeller swaps, oil samples, pump overhauls. You will also unblock toilets, fix cabin air conditioning and service the tenders and jet skis. Nobody hands a third the glamorous jobs, and nobody should. This is where you learn how a yacht actually works.

With guests aboard the rhythm changes. Maintenance gives way to keeping everything quiet and reliable. You stand engine room watches on passage, often the night watch, and respond fast to alarms. Guest-facing faults come first: a cabin too warm, a shower with no pressure, a water toy that will not start. In the yard or over winter in Antibes or Palma, you swing back to heavy maintenance, contractor supervision and the jobs that cannot be done while the yacht is busy.

Captains and chiefs hire thirds with an AEC, some workshop background and a good attitude. Ex-mechanics, apprenticed fitters, electricians and deckhands who have spent time below are all common routes in. A marine engineering cadetship gives you a strong start. Chiefs care about tidiness, honest logbooks and a willingness to get dirty without being asked. On 60m yachts you may be the only junior. On 100m+ you will sit in a structured team with clear watch rotas.

Progression runs through the MCA Small Vessel route. Sea time as a third counts towards your Y4, and once you hold it you can step up to second engineer on most yachts. From there, Y3, Y2 and Y1 open the way to first and chief engineer roles. Some engineers take the larger Unlimited route via EOOW if they want ships or the largest yachts. Two to three solid seasons as a third with good references is the usual pattern before promotion.
