STCW. ENG1. GUEST. RYA. Every guide to working on a superyacht throws acronyms at you from the first paragraph. Here's a plain-language breakdown of what you actually need — and in what order.
One of the most common mistakes people make when trying to enter the superyacht industry is spending money on the wrong qualifications first. There's no shortage of training providers happy to sell you courses — but not all certifications are equally valuable at the start of your career, and the wrong sequence can cost you both time and money.
Let's break this down into three clear tiers: what's mandatory, what's genuinely useful early on, and what can wait until you're already working.
Tier 1 — Mandatory. You Cannot Work Without These.
Required before any yacht over 24 metres
- STCW Basic Safety Training (BST) — This is the foundation. It covers personal survival, fire prevention, elementary first aid, and personal safety. It's an internationally recognised certificate required on any commercial vessel over 24 metres. Without it, no agency will register you, and no captain will hire you. Do this first.
- ENG1 Medical Certificate — A fitness-for-sea medical examination conducted by an MCA-approved doctor. It confirms you're medically fit to work at sea. Required for all crew on commercial yachts. Book this at the same time as your STCW — they're both prerequisites, not optional extras.
Tier 2 — Highly Recommended. Will Significantly Improve Your Chances.
Not mandatory, but expected by most captains
- GUEST Interior Crew Training — The industry standard for hospitality crew on superyachts. Covers service, housekeeping, laundry, wine and cocktail basics. If you're applying for a steward or stewardess position, this significantly strengthens your application. Many captains expect it.
- Powerboat Level 2 (RYA or IYT) — Allows you to operate the yacht's tender (small boat). Even interior crew are often asked to assist with tender operations. It's a short course, relatively inexpensive, and it immediately makes you more versatile onboard.
- VHF Radio Licence (SRC) — A short online or in-person exam. Qualifies you to operate marine VHF radio. Small investment, genuinely useful onboard, and it signals initiative to hiring agents.
Tier 3 — Wait Until You're Working.
Build these once you have sea time
- STCW Advanced Modules — Advanced fire fighting, medical first aid, security training. Typically required only as you progress into more senior roles. Your yacht will often fund these once you're employed.
- OOW / Deck Officer Qualifications — Relevant if you're pursuing a deck career path and want to eventually progress to officer or captain level. Not relevant for interior crew or early-stage entry.
- Wine, Sommelier, or Culinary Certifications — Genuinely valuable for experienced interior crew looking to specialise. Worth investing in once you know the direction your career is taking — not before your first season.
The Honest Advice Nobody Gives You
The superyacht training industry is a business. Many providers will suggest you take every course they offer before you even look for work. The reality is that STCW Basic Safety Training and an ENG1 medical are all you need to be registered with most crew agencies and to be considered for your first position.
Once you have those two things, register with agencies, start applying, and consider the Tier 2 courses as parallel investments — ideally before your first season begins. The GUEST interior course in particular is worth completing early if you're pursuing a steward or stewardess role.
Everything in Tier 3 can wait. In fact, many yachts fund advanced training for crew they want to retain — so you may not need to pay for those yourself at all.
