Why Are Experienced Yacht Crew Taking AEC1?

June proved to be an exceptionally busy month for our Approved Engine Course 1 (AEC1) programme at Seascope France. What stood out most was not only the number of aspiring deckhands and future assistant engineers attending the course, but also the growing number of experienced yacht officers choosing to gain this qualification.

So, why would an experienced officer need AEC1?

The answer lies in the increasing emphasis on competence, operational flexibility, and regulatory compliance within the yachting industry.

As modern yachts become more technically advanced, captains and management companies are looking for crew who can contribute beyond their primary role. A deck officer with a recognised engineering qualification is often able to support the engineering department during routine maintenance, machinery inspections, bunkering operations, and emergency situations. This additional competence  improves onboard efficiency and strengthens the overall capability of the crew.

One important factor driving demand for AEC1 is the vessel's Minimum Safe Manning Document (MSMD). This document specifies the minimum number of qualified crew required to operate the yacht safely, taking into account factors such as the vessel's size, machinery, operational area, and watchkeeping arrangements.

While the MSMD defines the minimum legal manning level, many yachts choose to exceed these requirements by employing crew with additional qualifications. Having deck crew who understand marine engineering systems provides greater operational resilience and allows them to assist engineers safely during day-to-day operations.

A Practical Example

Imagine a yacht whose Minimum Safe Manning Document requires:

• 1 Chief Engineer
• 1 Engine Rating

Rather than employing a dedicated engine rating, some smaller yachts may choose to employ a deckhand who also holds AEC1 (along with any other qualifications required by the Flag State and the vessel's operating procedures). This crew member can provide valuable support to the engineering department by assisting with daily engine room rounds, generator inspections, fuel and oil transfers, planned maintenance, emergency response, machinery space watchkeeping (where permitted by the vessel's procedures and Flag State).

It is important to note that AEC1 alone does not qualify a crewmember to replace a certificated engineer or automatically satisfy a Safe Manning requirement. However, it provides recognized engineering competence, demonstrates technical knowledge, and makes that crewmember significantly more valuable onboard by increasing operational flexibility.

This is also something surveyors increasingly take into consideration. During annual surveys, flag state inspections, class surveys, or insurance inspections, surveyors are interested not only in the condition of the machinery but also in the competence of the people operating and maintaining it. Questions about machinery rounds, fuel transfer procedures, engine room safety, and emergency response are becoming increasingly common.

For experienced officers, obtaining AEC1 is therefore much more than adding another certificate to their CV. It demonstrates a proactive approach to professional development, broadens technical understanding, and enables crew to work more effectively across departments.

For crew planning to pursue an engineering career, AEC1 also forms the first recognised step towards Approved Engine Course 2 (AEC2) and the UK Maritime and Coastguard Agency's Small Vessel Engineer certification pathway.

Whether you are entering the industry for the first time or are already serving as an officer onboard, AEC1 continues to be one of the most valuable technical qualifications a yacht crewmember can hold. As June has shown, the industry's demand for multi-skilled, technically competent crew is only continuing to grow.
