What Is STCW and Why Does It Matter?
The STCW Convention was adopted by the International Maritime Organization (IMO) in 1978 and significantly updated in 1995 and 2010 (Manila Amendments). It sets internationally agreed standards for the training, certification, and watch-keeping of officers and crew aboard seagoing ships. Any vessel operating commercially must comply with STCW — and that includes yachts operating under a commercial flag carrying paying passengers or charter guests.
In practical terms, the moment you step aboard a commercially-flagged yacht as a paid crew member, you are legally required to hold a valid STCW certificate. Port State Control officers can inspect vessels at any time and detain a ship if crew do not hold valid documentation. Captains take this seriously, and any reputable crewing agency will require your STCW before even submitting your profile.
STCW Basic Safety Training (BST) — The Foundation
The STCW Basic Safety Training package (Regulation VI/1) is the entry-level requirement for all seafarers. It is made up of four individual courses that can typically be completed in a single week at an approved maritime training centre. The combined cost ranges from approximately £350–£600 depending on the training provider and location.
Personal Survival Techniques (PST)
Covers the practical skills needed to survive a maritime emergency: abandoning ship, using immersion suits and lifejackets, boarding and managing survival craft, and signalling. Includes in-water exercises in a pool. Duration: 1 day. Validity: 5 years (revalidation required).
Fire Prevention and Fire Fighting (FPFF)
Teaches fire classes, extinguisher types, alarm systems, fire patrol procedures, and practical live fire-fighting with breathing apparatus. Fire at sea is one of the most dangerous scenarios a crew will face. Duration: 1 day. Validity: 5 years.
Elementary First Aid (EFA)
Basic first aid skills relevant to on-board emergencies: CPR, bleeding control, fracture management, and medical emergencies in a remote environment where evacuation may take hours. Duration: 1 day. Validity: no formal renewal but many employers prefer recent certificates.
Personal Safety and Social Responsibilities (PSSR)
Covers the human element in maritime safety: crew responsibilities, fatigue and watch-keeping regulations, drugs and alcohol policy, working relationships, and environmental protection. Mostly classroom-based. Duration: half day.
Advanced STCW Certificates — Who Needs What?
Beyond Basic Safety Training, specific roles require additional certificates. The key variables are vessel size (gross tonnage), flag state, and your role onboard. Here is a summary of the most common advanced requirements for yacht crew:
| Certificate | Who Needs It | Validity |
|---|---|---|
| HELM (Operational) | Deck officers (OOW level) | 5 years |
| Advanced Fire Fighting (AFF) | Officers, chief stews, senior crew | 5 years |
| Medical Care (MC) | Captain, Chief Officer, Chief Stew | 5 years |
| Proficiency in Survival Craft (SCRB) | Officers, bosun, senior stews | 5 years |
| GMDSS (General Operator Certificate) | Any officer responsible for radio comms | No expiry (revalidation not required) |
| Ship Security Officer (SSO) | Captain or nominated officer on commercial vessels | No expiry |
The ENG1 Medical Certificate
While not technically an STCW certificate, the ENG1 (or equivalent seafarer medical certificate) is equally mandatory and will be required alongside your STCW. This is a medical examination carried out by an MCA-approved doctor that confirms you are fit to work at sea. It covers eyesight, hearing, cardiovascular health, and general fitness.
Cost: approximately £50–£150 in the UK. Validity: 2 years for crew under 40, annually for those over 40. Some flag states (Marshall Islands, Cayman Islands) accept equivalent medical certificates from their own approved doctors. Always check the specific requirements of the vessel's flag before your joining date.
Where to Get Your STCW Certificates
STCW courses must be completed at an approved training centre. In Europe, the main hubs are in the UK (Warsash Maritime Academy, OOC International, CPSA, BMT), Spain (ISM Ibérica in Palma), France (Antibes Maritime Training Centre), and the Netherlands. In the Americas, Fort Lauderdale and Miami have multiple approved providers including MPT Maritime and STAR Center.
The BST package typically runs Monday to Friday and costs between £400 and £550 in the UK. If you are based in Spain or France, expect to pay €450–€700. Courses are offered multiple times per month and fill up quickly in spring (March–May) when crew are preparing for the Mediterranean season, so book well in advance.
After completing each course, the training centre issues a certificate. You will then apply to the Maritime and Coastguard Agency (MCA) or your flag state's maritime authority for your official STCW Certificate of Competency or Endorsement. Keep digital and physical copies — you will need them for every job application.
