What does STCW stand for?
STCW stands for the Standards of Training, Certification and Watchkeeping for Seafarers — an international convention adopted by the International Maritime Organization (IMO) in 1978 and significantly updated in 1995 and 2010 (the "Manila Amendments").
In plain terms, STCW is the global rulebook that says: if you want to work professionally at sea, you must meet these minimum standards of safety training. Flag states (the countries whose flag a vessel sails under) enforce STCW compliance as a condition of operating commercially.
For crew on superyachts and larger commercial yachts, this means you must hold a valid STCW certificate to be legally employed on board.
What is STCW Basic Safety Training?
STCW Basic Safety Training (BST) — sometimes called the "STCW 95" or the "safety pack" — is the entry-level qualification required for all crew regardless of role. It consists of four separate elements that are usually taught together as a single four-day course:
| Element | What it covers |
|---|---|
| Personal Survival Techniques (PST) | Abandoning ship, survival craft, lifebuoys, hypothermia prevention, distress signals |
| Fire Prevention and Firefighting (FPFF) | Fire triangle and fire spread, extinguisher types, breathing apparatus, firefighting practical |
| Elementary First Aid (EFA) | CPR and AED, treating bleeding and shock, fractures, burns, drowning response |
| Personal Safety and Social Responsibilities (PSSR) | Watch-keeping duties, teamwork, emergency drills, fatigue awareness, crew communication |
Completing all four elements earns you the STCW Basic Safety Training certificate. In some countries this is recorded in a Seafarer's Record Book or discharge book; in others it is a standalone certificate. The UK's Maritime and Coastguard Agency (MCA) issues endorsements into an STCW Certificate of Competency or a Seafarer's Record Book.
How long is the STCW course and what does it cost?
Most providers run STCW Basic Safety Training as a four-day residential course. Some providers offer a five-day format to allow more time on practical exercises. The course includes classroom instruction and practical assessments (including an actual firefighting drill and time in a pool for survival techniques).
In the UK, courses typically cost £350–£600 including all materials and assessments. Accommodation may be additional depending on the venue.
Reputable UK providers include:
- Sea Safety Training
- Warsash Maritime Academy (Southampton)
- Glasgow Maritime Academy
- Falmouth Marine School
- Various RYA-recognised centres across the UK and overseas
Verify the provider is MCA-approved. STCW training must be delivered by an approved provider. Check the MCA's list of approved training providers before booking. Overseas courses are acceptable if the provider is recognised by the flag state your yacht sails under.
How long does STCW last?
Your STCW Basic Safety Training certificate is valid for five years from the date you completed the course.
After five years you must complete a refresher course — typically one or two days — to renew. You cannot simply let it expire and renew later: if your STCW lapses while you are employed, you are not legally compliant to work on board.
Renewal timing matters. STCW refresher courses fill up quickly, particularly in the spring before the Mediterranean season. If you leave it too late you may find no availability before your certificate expires. YachtSync sends reminders at 180, 90, 30, 14 and 7 days before expiry — that gives you six months of warning to book a course.
What other STCW certificates exist beyond Basic Safety Training?
BST is the foundation, but STCW includes many other certifications that become relevant as you progress in your career:
| Certificate | Typically required for | Validity |
|---|---|---|
| STCW BST (Basic Safety Training) | All crew on commercial yachts | 5 years |
| Crowd Management | Crew on vessels carrying 12+ passengers | 5 years |
| Crisis Management and Human Behaviour | Senior crew on passenger yachts | 5 years |
| PDSD (Proficiency in Designated Security Duties) | Crew on vessels over 500GT | Does not expire |
| Medical Care (STCW A-VI/4) | Officers designated as ship's medical officer | 5 years |
| Advanced Firefighting | Deck and engineering officers | 5 years |
Tracking which of these you hold, their expiry dates, and when to book renewals is where most crew — even experienced ones — lose track. YachtSync covers all of them.
STCW and the superyacht industry
Superyachts operating commercially (on charter) must comply with the Large Yacht Code (LY3) in the UK or equivalent flag state codes. These codes reference STCW directly as the minimum crew certification standard.
Most private superyachts voluntarily follow the same standards. Whether a yacht is commercially operated or privately owned, captains and owners expect crew to hold valid STCW — it is simply professional standard.
Crew without a valid STCW certificate are a compliance risk to the vessel and will not be hired by serious captains or management companies.
Never let your STCW catch you out.

How to track and share your STCW certificate
The practical challenge with STCW — and with maritime certificates generally — is that they need to be:
- Stored somewhere you can find them instantly when a captain asks
- Correctly named (not "scan0047.pdf") so they look professional when shared
- Tracked for expiry so you book renewals in time
- Shareable quickly — captains and agents expect your paperwork on short notice
YachtSync handles all four. Scan your STCW certificate with the AI scanner and it extracts the expiry date automatically, renames the file to your preferred naming convention, and adds it to your shareable certificate portfolio. You can then send your full cert folder to a captain or agent in a single tap from your phone.
The free tier covers 20 certificates and 3 AI scans — enough to store your STCW, ENG1 and all your other entry-level certs at no cost.
