Articles Yacht Crew Explained: Who Does What On Board?

15 Jun 2026 | Industry Insight

From the Captain on the bridge to the chef in the galley, every superyacht runs on a carefully structured crew working to a clear hierarchy. This guide explains the departments, the roles within them and how the team scales with the size of the vessel.

Every superyacht that runs smoothly does so because of a precisely organised crew working to a clear hierarchy behind the scenes. Whether you are chartering a vessel for the first time or considering ownership, understanding who does what on board gives you a clearer picture of what makes a great yacht operation and what to expect from the team entrusted with your experience.

Key Takeaways

A superyacht crew is organised into four departments: deck, interior, engineering and galley, each led by a department head who reports to the Captain.
Crew numbers scale significantly with vessel size, from a team of 6 or 7 on a 30-metre yacht to 30 or more on the largest superyachts, with roles becoming increasingly specialised as the vessel grows.
On smaller yachts, crew often work across departments in hybrid roles. On larger vessels, each position is distinct, with clearly defined responsibilities and reporting lines.
Beyond the four core departments, larger superyachts may carry specialist crew including a purser, diving instructor, masseuse, personal trainer or nanny, depending on the Owner's schedule and preferences.

How Many Crew Does a Superyacht Need?

Crew numbers vary considerably depending on the length of the vessel, whether it operates as a private or charter yacht, and the standard of service the Owner requires. SOLAS and MLC regulations set minimum safe manning levels, but most superyachts carry more crew than the legal minimum in order to deliver the experience guests expect. As a working guide, charter yachts typically carry roughly one crew member for every three to four metres of vessel length.

Vessel Length	Typical Crew Size	Notes
Up to 30m	4 to 7	Hybrid roles common; Captain may stand watches
30 to 50m	8 to 14	Core departments established; some role overlap remains
50 to 70m	15 to 22	Fully specialised departments; purser often introduced
70m+	25 to 40+	Specialist crew common; full department head structure

All crew operate within one of four departments: deck, interior, engineering and galley. Each has a head who reports directly to the Captain, and each has a clearly defined sphere of responsibility. On smaller yachts the boundaries between departments are more fluid; on larger vessels they are sharply defined.

The Deck Department

The deck department is responsible for the safe navigation and operation of the vessel, the maintenance of its exterior and the delivery of outdoor guest activities. It encompasses roles from the Captain down to the most junior deckhand.

Captain

The Captain holds ultimate authority and responsibility for the vessel, crew and guests. The role extends well beyond navigation to encompass crew management, compliance, financial oversight and Owner liaison.

First Officer (Chief Officer)

The first officer is second in command and the Captain’s deputy on the bridge. They manage the deck crew day-to-day, oversee watch scheduling, coordinate safety drills and maintain the crew certification records that keep the vessel compliant. In the Captain’s absence, the first officer assumes command. On yachts under 40m, this is not always a dedicated position, and those responsibilities typically rest with the Captain directly.

Bosun

The bosun is the senior deckhand and working team leader for the deck crew. They are responsible for the maintenance and cleanliness of the yacht’s exterior, the condition of deck equipment and the management of the watertoys inventory. The bosun drives tenders, oversees watersports operations and is often the primary point of contact between guests and outdoor activities on board.

Deckhands

Deckhands are responsible for the exterior presentation of the vessel and a broad range of practical tasks, including washing and maintaining the hull and topsides, handling lines during docking and anchoring, watertoys deployment and operating the tender for guest transfers to shore.

The Interior Department

The interior department is responsible for the guest experience inside the vessel. Housekeeping, meal service, drinks, laundry, cabin presentation and the day-to-day wellbeing of guests on board all fall within its remit. On a charter yacht, the quality of the interior team is one of the most direct influences on whether guests choose to rebook.

Chief Steward

The Chief Steward heads the interior department and sets the standard for everything the guest encounters inside the yacht. They oversee all housekeeping, table and bar service, cabin turndown, laundry and interior provisioning, and manage the interior team directly. They are the primary interior liaison for both the Captain and the Owner, and on larger vessels work closely with the purser on budgeting and the management of guest preferences ahead of each voyage. On a large charter superyacht, the Chief Steward typically manages a team of four to six interior crew, maintaining standards comparable to a five-star hotel around the clock.

Stewards

The team of stewards supports the Chief Steward across all interior functions: cabin housekeeping, meal and drinks service, bar management, laundry and guest liaison. On smaller yachts a single steward may carry all of these responsibilities; on larger vessels, team members often specialise in housekeeping, service or laundry roles respectively.

Purser

The purser is found on larger superyachts, typically those of 50m and above. They act as the vessel’s administrative manager, handling accounts, payroll, provisioning budgets, port clearances and crew documentation. The purser frees the Captain from the most paperwork-intensive elements of running the vessel, and typically brings a background in hospitality management or financial administration rather than a maritime career path.

The Engineering Department

The engineering department is responsible for the mechanical, electrical and electronic systems that keep the vessel operating safely and efficiently. It is the least visible department from a guest’s perspective and one of the most consequential. A well-run engineering department is one that the passengers never need to think about.

Chief Engineer

The Chief Engineer oversees all technical systems on board, including main engines, generators, watermakers, stabilisers, air conditioning, hydraulics and all auxiliary systems. They manage the engineering team, maintain planned maintenance schedules and coordinate with shipyards during refit periods. The mechanical complexity of a modern superyacht is considerable, and the cost of a preventable breakdown in a remote location far outweighs the investment in an experienced and well-qualified engineer.

Second Engineer and ETO

The second engineer supports the Chief across all technical areas and covers engineering watches on passage. On larger vessels an Electro-Technical Officer (ETO) is also carried, responsible for the yacht’s audio-visual systems, IT infrastructure, navigation electronics and communications equipment. On smaller yachts, those responsibilities are typically absorbed by the Chief Engineer or a technically capable senior deckhand.

The Galley Department

The galley department covers all food preparation on board, from guest dining to crew catering. On a charter yacht, the quality of the food is consistently one of the most commented-upon aspects of the experience, and a talented Head Chef is a significant asset to the vessel’s charter programme.

Head Chef

The Head Chef manages all aspects of galley operations: menu planning, guest meal preparation, crew catering, provisioning and galley hygiene. They are typically trained to a high professional standard, with experience drawn from restaurants, hotels or private household service. On a charter yacht, menus are bespoke for each guest party, produce is sourced locally where possible and all dietary requirements and allergies across guests and crew must be managed, frequently at short notice and in varying provisioning conditions.

Sous Chef and Crew Cook

The sous chef supports the Head Chef across all galley operations and may independently prepare crew meals on larger vessels during busy charter periods. Some yachts carry a dedicated crew cook as a separate role. On smaller yachts the Head Chef works alone, covering both guest and crew catering without support.

Specialist Crew and Hybrid Roles

Larger superyachts frequently carry specialist crew beyond the four core departments, shaped by the Owner’s schedule. Common additions include a diving, masseuse or wellness therapist, personal trainer, nanny or childcare specialist, and on some privately owned vessels, a security officer. On smaller yachts, these functions are typically handled by existing crew members who hold additional qualifications in the relevant area.

On yachts under 35m, formal department boundaries are more fluid and crew regularly work across two areas. The most common hybrid arrangements are the deck/steward, who moves between exterior maintenance and interior service; the engineer/deckhand, covering both technical and deck duties; and the steward/cook on vessels without a dedicated chef. Hybrid crew are not a compromise. On a well-run smaller yacht, a versatile team often delivers a warmer, more personal experience than a rigidly structured one.

Understanding the Crew Behind Your Voyage

A superyacht crew is a carefully considered team, structured so that every aspect of life on board is managed by someone with the right skills and the right authority. Understanding who is responsible for what gives owners and charterers a clearer basis for asking the right questions when evaluating a vessel or structuring a crew package.
