A candidate sends the captain a CV listing eleven certificates. The captain glances at it for four seconds, checks two of them, and forms an opinion. You need to know which two he checked and why — because the other nine are not worthless, they simply answer a different question.
Three Categories, Three Questions
| Type | Example | The question it answers | What happens without it |
|---|---|---|---|
| Regulatory | STCW Basic Safety, ENG1, PSA (Proficiency in Security Awareness) | Are you legally allowed to be on this vessel? | You cannot sail. Non-negotiable. |
| Vocational award | Food Safety Level 2, WSET Level 1/2, barista certificates | Have you been trained to a recognised outside standard in one skill? | You can still work; you look less prepared |
| Industry CoC | The IAMI GUEST Certificate of Competency (Junior, Senior, Chief Steward(ess)) | Have you been assessed as competent against the industry framework for yacht interior work? | You can still work; promotion and better boats get harder |
What Each Is Actually Worth to an Employer
- Regulatory certificates are a filter, not a feature. No captain is impressed that you hold an ENG1 — but a lapsed one takes you out of the running instantly. Track the expiry dates like you track the boss trip dates.
- Vocational awards are proof of external standards. A WSET or a Food Safety certificate says a body with nothing to gain examined you and passed you. That is why GUEST recognises some of them as equivalents for its own units.
- The GUEST CoC is a credibility signal. It says you have been assessed against a shared industry benchmark by an IAMI-approved provider, that you have logged sea service, and that you have kept a training record. On a well-run boat it is increasingly expected at senior and chief level.
The Hierarchy Nobody Prints
For a junior role: regulatory certificates are everything, experience is next, GUEST is a strong differentiator. For a senior role: GUEST Advanced units and demonstrated service start to carry real weight. For a chief stew or purser role: management-level competence — budgets, HR, ISM awareness — is what separates candidates, and GUEST Management units are the most legible way to evidence it.
Say This Out Loud in an Interview
"My STCW and ENG1 are current to [date]. I hold Food Safety Level 2 and WSET Level 1. I have completed the GUEST Introduction units through an approved provider and I am logging service towards Advanced." That sentence tells a captain your legal status, your external standards and your trajectory in about ten seconds.
Onboard Notes
- Build a single certificate table: name, awarding body, issue date, expiry, where the original is stowed.
- Never call the GUEST CoC a licence, and never call an STCW course a "qualification" in the vocational sense — the words matter to people who hire.
- These lessons prepare you; only an approved GUEST Training Provider can assess and certify you.
