The question that most first-time charter guests ask is where to go. The question they should ask first is how big. The size of the yacht is not a luxury gradient - more money for more space. It is a choice about the kind of experience you want, and it shapes everything from the anchorages available to you to the relationship you have with the water, the crew, and the other guests.
There is no right answer. There is only the answer that fits what you are looking for, and the purpose of this guide is to help you find it.
Under 30 Metres: The Intimate Experience
A yacht between 20 and 30 metres - roughly 65 to 100 feet - is the size that most people picture when they think of a charter, and it is the size that delivers the most direct connection to the sea. You feel the water. You hear it against the hull at night. When the yacht is under sail, you feel the heel and the acceleration in your body. When it is at anchor, you feel the gentle rock that research suggests improves sleep quality.
The crew on a yacht of this size is typically four to six people: a captain, a chef, a steward and one or two deckhands. This is small enough that the dynamic is personal. The captain is not a distant figure on the bridge; they are the person who sits down with you over coffee on the first morning and asks what you want from the week. The chef is not behind a closed galley door; they are visible, accessible, often eating with you. The relationship that develops over the course of a week on a smaller yacht is closer to a collaboration than a service transaction.
The practical advantages of a smaller yacht are significant for a wellness charter. Smaller yachts access shallower anchorages, narrower channels and more secluded bays. They can tuck into coves that a larger vessel cannot enter. In the Greek islands, this means anchoring in bays where the water is three metres deep and the nearest road is a goat track. In Croatia, it means threading through the channels between the smaller islands where the larger charter yachts cannot follow. In the Maldives, it means anchoring inside the atoll lagoons where the water is calm and the reef is directly below you.
The accommodation on a yacht of this size is comfortable but compact. Cabins are well-designed, typically with en-suite bathrooms, but they are not suites. Storage is limited. Deck space is shared, and on a yacht carrying eight to ten guests, the foredeck, the cockpit and the swim platform are communal spaces that function best when everyone is comfortable with proximity.
For a wellness charter, this intimacy is usually an advantage. The enforced closeness, the shared meals, the fact that you cannot really avoid anyone for long, produces a social dynamic that is more like a house party than a hotel stay. Guests who might maintain polite distance in a larger setting find themselves in genuine conversation by the second day, because the yacht does not allow the kind of selective engagement that a larger space permits.
Best for: couples, small groups of friends, families with older children, anyone who values connection to the water over space and amenity.
30 to 50 Metres: The Balanced Charter
A yacht between 30 and 50 metres occupies the middle ground, and for many wellness charters it is the sweet spot. There is enough space for privacy - a master cabin that feels like a proper bedroom, guest cabins with room to unpack, multiple deck areas where you can find a quiet corner. But the yacht is still small enough that you feel the water, still manoeuvrable enough to access most anchorages, and still crewed at a scale where the service is personal.
The crew on a yacht of this size is typically six to twelve people, and the division of roles becomes more defined. There is often a dedicated chief steward managing the interior, a chef with a sous chef or assistant, and a deck team responsible for the water toys, the tenders, and the sailing. The captain coordinates the itinerary but delegates more of the day-to-day guest interaction to the steward team.
The deck space is the key difference. A 40-metre yacht typically has a foredeck large enough for yoga, an aft deck large enough for dining, a flybridge with its own seating area, and a swim platform that deploys to create a genuine waterside terrace. This means that a group of eight or ten guests can spread out, find their own spaces, and come together for meals and activities without feeling either crowded or isolated.
The water toys expand significantly at this size. A yacht of 35 metres or more will typically carry paddleboards, kayaks, snorkelling equipment, and a tender large enough to take the whole party ashore. Larger yachts in this range may carry a jet ski, a sailing dinghy, or diving equipment with a compressor. For a wellness charter focused on active engagement with the water, this range of equipment matters - it means the water is not just something you look at but something you interact with in multiple ways throughout the day.
Best for: groups of six to twelve, families with children of mixed ages, corporate retreats with a small leadership team, anyone who wants both togetherness and the option of solitude.
Over 50 Metres: The Grand Experience
A yacht over 50 metres is a different proposition entirely, and whether it suits a wellness charter depends on what kind of wellness you are seeking.
The advantages are obvious: space, comfort, amenity. A 60-metre yacht might have a spa with a massage room and a sauna. It will have a gym. It will have multiple dining areas, a cinema, a lounge that could host a cocktail party for thirty. The master suite will be larger than many hotel rooms. The crew - typically fifteen to twenty-five people - will deliver a level of service that is seamless and anticipatory. You will not carry your own towel to the swim platform. You will not wait for anything. The experience is frictionless in a way that smaller yachts cannot replicate.
The trade-offs are less obvious but significant. A yacht of this size does not access the same anchorages as a smaller vessel. The draft is deeper, the turning circle wider, and many of the intimate coves and shallow bays that define the best wellness itineraries are simply not available. In the Greek islands, a 60-metre yacht will anchor in the larger bays and harbours rather than the hidden coves. In Croatia, it will use the main ports rather than the secret anchorages between the islands. The experience is magnificent but it is not intimate in the same way.
The relationship with the water also changes. On a 25-metre sailing yacht, the sea is right there - you can trail your hand in it from the cockpit. On a 60-metre motor yacht, the sea is below you, viewed from a height, and the swim platform feels more like descending to the water than stepping into it. The yacht itself becomes more of the experience. On a smaller yacht, the yacht is a vehicle for the experience of the sea. The distinction matters for a wellness charter, where the goal is often to feel closer to the natural environment rather than insulated from it.
That said, a larger yacht offers something that smaller vessels cannot: genuine separation. On a corporate retreat with ten or twelve people who need both collaborative space and private space, a yacht of this size provides both without compromise. On a multi-generational family charter, it allows teenagers to disappear to the cinema while grandparents read on the sundeck and parents swim from the platform. The privacy is real and it is valuable, particularly for guests who find that constant togetherness, however pleasant, is draining over the course of a week.
Best for: larger groups, multi-generational families, corporate retreats requiring both meeting and social space, guests who prioritise comfort and amenity alongside their wellness experience.
Sail or Motor
The choice between a sailing yacht and a motor yacht is distinct from the choice of size, although the two are related. Motor yachts dominate the larger end of the market. Sailing yachts rarely exceed 50 metres and most charter sailing yachts are in the 20 to 40 metre range.
The experience of sailing is itself a wellness practice, although it is not often described in those terms. The wind in the rigging, the heel of the hull, the rhythmic motion through the water, the silence when the engine is off and the yacht is moving under sail alone - these produce a sensory environment that is qualitatively different from motor cruising. The pace is slower. The route is shaped by the wind as well as by the itinerary. There is an element of engagement with the natural environment that motor cruising, for all its comfort and efficiency, does not provide.
Motor yachts offer stability, speed and space. They get you where you want to go faster and with less dependence on conditions. The ride is smoother, the deck space is more usable in all conditions, and the interior layout is typically more generous. For guests who are prone to seasickness, or who value a predictable schedule, or who want to cover more ground in a week, a motor yacht is the practical choice.
Many wellness charters compromise with a sailing catamaran, which offers the space and stability of a motor yacht with some of the sailing character of a monohull. Catamarans are particularly popular in the Caribbean and the Maldives, where the calm waters and steady trade winds suit their design perfectly.
The Right Question
The right yacht is the one that matches your intention for the week. If you want to feel the sea, choose smaller. If you want to feel held, choose larger. If you want to sail, choose a sailing yacht. If you want to arrive, choose a motor yacht. If you want both, choose a catamaran.
The charter broker’s job is to help you navigate these choices, and a good broker will ask about your experience before they ask about your budget. They will want to know how many guests, what ages, what activities, what level of physical engagement with the water, and what your idea of a perfect day looks like. From those answers, the right yacht reveals itself, and it is not always the one you expected.
Yacht selection is one of the most important decisions in planning a wellness charter. Your charter broker will guide you through the options based on your group size, destination, activity preferences and wellness goals. We recommend discussing your requirements early, as the best yachts for wellness charters book well in advance, particularly in peak season.
