How the interior career works
Interior crew, stewards, stewardesses, housekeepers and chief stewardesses, are the only department in yachting without a formal MCA Certificate of Competency ladder. There is no statutory qualification that must be held to progress from junior stewardess to chief stewardess. What drives careers in interior is experience, demonstrable service standards, captains' references, and leadership ability.
The two documents every interior crew member needs regardless of any other factors are STCW Basic Safety Training and an ENG1 seafarer medical. These are mandatory for all professional crew under the Maritime Labour Convention. Without both, no captain can hire you. The MCA sets out the basic training requirement in MSN 1865 (M) Amendment 1:
"Seafarers employed or engaged in any capacity on board ship on the business of that ship as part of the ship's complement with designated safety or pollution-prevention duties in the operation of the ship shall, before being assigned to any shipboard duties: successfully complete those elements of basic training given by an MCA approved training provider. The 4 elements of basic training are: Personal Survival Techniques (STCW Code, Table A-VI/1-1); Fire Prevention and Fire Fighting (STCW Code, Table A-VI/1-2); Elementary First Aid (STCW Code, Table A-VI/1-3); Personal Safety and Social Responsibilities (STCW Code, Table A-VI/1-4)."
MSN 1865 (M) Amendment 1, section 3.1 · Read the full notice on gov.uk
There is no interior-specific MCA Merchant Shipping Notice. The statutory requirements that catch interior crew are the general seafarer ones: STCW basic training under MSN 1865 (M) Amendment 1, an ENG1 medical under MSN 1886 (M+F) Amendment 3, PDSD on vessels of 500 GT and over, and, for crew who handle or prepare food, the catering staff food hygiene requirements of MSN 1846 (M) Amendment 1. That absence is an answer in itself: with no MCA ladder to climb, interior progression runs on experience, service standards and references. Under MSN 1886 (M+F) Amendment 3, the ENG1 certificate (form MSF 4104) is valid for a maximum of 2 years for anyone over 18, and 1 year for candidates under 18.
The voluntary industry framework is the GUEST programme (Guidelines for Unified Excellence in Service Training), with Certificates of Competency issued by PYA on behalf of IAMI. GUEST is widely respected and increasingly expected on larger yachts, but it is not a statutory MCA requirement.
Entry level for interior crew. STCW BST and ENG1 are the only statutory requirements to start working. GUEST I (Yacht Junior Interior Crew CoC) requires no previous yacht service and is a good first step that demonstrates commitment to professional development. Practically, hospitality experience, food handling certificates, and fine dining or cocktail knowledge are valued by captains and crew agents at this stage.
Sea time: no minimum to startAfter one or more seasons as junior interior crew, progression to steward/stewardess is performance-led. PDSD (Proficiency in Designated Security Duties) becomes mandatory on vessels over 500 GT at this stage. GUEST II requires a minimum of 12 months total yacht service plus 60 days guest service and covers advanced food and beverage service, laundry, and housekeeping at an intermediate level.
Sea time: 12 or more months interior experience (industry norm)The second officer of the interior department on most medium yachts. Crowd Management and Crisis Management/Human Behaviour STCW endorsements are required on passenger-carrying yachts and larger commercial vessels for senior crew. GUEST II requires 12 months total yacht service and 60 days guest service to apply.
Sea time: 2 or more years interior experience typicallyA senior department-head position responsible for the entire guest experience, provisioning, budget management, and managing the interior team. There is no MCA statutory qualification unique to this role beyond those already described. GUEST III requires a minimum of 24 months total yacht service plus 120 days guest service, and covers destination and event management, human resources, budgeting, and leadership. In practice, most chief stew positions require substantially more experience than the GUEST III minimum.
Sea time: 3 or more years interior experience typically · GUEST III minimum: 24 months total yacht service + 120 days guest serviceOn the largest superyachts (typically 70m or more), the Interior Manager is a standalone senior role that oversees both the service and housekeeping tracks, often managing a team of 6 to 10 interior crew. This is an industry role designation, not a statutory qualification. It requires a track record as chief stewardess on multiple large yachts.
Found primarily on 70m+ vessels with dedicated interior management structuresThe GUEST programme in plain English: GUEST is issued by PYA (Professional Yachting Association) on behalf of IAMI. It is voluntary, not mandatory. GUEST I has no sea-service entry requirement. GUEST II needs 12 months total yacht service and 60 days guest service. GUEST III needs 24 months total yacht service and 120 days guest service. These are industry certificates, not MCA CoCs. PYA website
What actually moves interior careers
Unlike deck or engineering, where each stage is gated by a formal MCA qualification, interior careers advance on the strength of:
- Captain's references, a strong reference from a respected captain is worth more than any voluntary certificate
- Service standards, fine dining, silver service, cocktails, wine knowledge (WSET is widely valued), and high-end hospitality experience from shore
- Housekeeping skills, on 50m+ yachts, specialist housekeeping, floristry and yacht detailing experience is sought
- Discretion and professionalism, interior crew work in close proximity to UHNW owners and guests; discretion is valued at all levels
- Seasonal consistency, working the same vessel across multiple seasons demonstrates reliability and trust
Day to day at each rank
Junior / 3rd stewardess
Most of the day is housekeeping and laundry: cabin turndowns and full turnarounds between guest trips, heads and detailing, guest laundry, crew uniform pressing, and supporting service at meal times by polishing glassware and silverware and running plates. On charter you will also set cabins up from the guest preference sheets, the document the interior team builds for every trip covering everything from pillow firmness to how each guest takes their coffee. You report to the 2nd or chief stewardess.
2nd stewardess
Usually the head of service or head of housekeeping, depending on how the chief stew splits the department. On the service side that means table settings, silver service and synchronised plating at formal dinners, wine and cocktail service, and bar stock. On the housekeeping side it means owning the cabin and laundry programme and its standards checklist. The 2nd stew is also the chief stew's deputy: running the interior when the chief is off rotation or ashore, briefing juniors from the preference sheets, and training new stews on the job. Reports to the chief stewardess.
Chief stewardess
A head of department alongside the chief officer, chief engineer and chef. The chief stew owns the whole guest experience: preference sheets and guest liaison, interior provisioning and budget, uniform and wardrobe, florals and tablescaping, themed dinners and events, plus rotas, appraisals and written references for the interior team. On most yachts the chief stew reports directly to the captain and works hand in hand with the chef on service timing.
How the team scales with vessel length
Typical interior teams: a sole stew or a two-stew team on yachts around 30 to 40m, where everyone does everything; roughly three to five interior crew on 45 to 60m, which is where service, housekeeping and laundry start splitting into dedicated roles; and six to ten or more on 70m+, often under an interior manager or purser, with specialists in laundry, housekeeping, service and sometimes floristry. These are industry norms rather than fixed rules; every programme staffs differently.
STCW endorsements that apply to interior crew
- PDSD, required on vessels over 500 GT (no expiry)
- Crowd Management, required on vessels carrying 12 or more passengers
- Crisis Management and Human Behaviour, required for senior interior crew with muster station responsibilities on passenger-carrying vessels
How much do superyacht interior crew earn?
Interior pay rises with rank and the size of the interior team:
| Role | Indicative monthly pay |
|---|---|
| Junior stewardess | €2,500 to €3,500 |
| Second / service stewardess | €3,000 to €4,500 |
| Chief stewardess | €4,500 to €8,000 |
| Purser | €6,000 to €10,000+ |
Indicative monthly ranges in euros, the industry standard currency. Pay scales with vessel size, rotation and flag, and excludes tips and bonuses. Figures are blended from published 2026 yacht crew salary guides (YPI Crew, Foreland Marine and others); always confirm current rates before relying on them.
Where to train: superyacht interior and stewardess courses

Official source documents
Everything statutory on this page traces back to these MCA Merchant Shipping Notices on gov.uk:
- MSN 1865 (M) Amendment 1, STCW basic training: the four elements quoted above, given by an MCA approved training provider
- MSN 1886 (M+F) Amendment 3, the seafarer medical examination system: the ENG1 certificate is form MSF 4104, valid for a maximum of 2 years for anyone over 18 and 1 year for candidates under 18
- MSN 1846 (M) Amendment 1, food and catering under MLC 2006: the food hygiene requirements for catering staff, which cover interior crew who handle or prepare food
Note what is missing: there is no MSN for interior ranks themselves. The stewardess, 2nd stewardess and chief stewardess ladder is industry convention rather than MCA regulation, which is why experience and references carry the weight, and why GUEST is an industry programme issued by PYA on behalf of IAMI rather than an MCA certificate.
