Prime superyacht berths have evolved from a simple operating expense into valuable long-term rights shaped by scarcity, larger yachts, limited marina capacity and growing investor interest in waterfront infrastructure.
A marina berth used to be regarded as one of the unavoidable costs of owning a yacht. You bought the yacht, found somewhere convenient to keep it and paid the marina each year for the privilege. The berth was infrastructure rather than an asset: a rectangle of water beside a pontoon, useful because the yacht needed somewhere to live when nobody was cruising.
That view has changed dramatically in some of the world's most desirable yachting destinations. A berth in the right marina can now involve a multimillion-euro financial commitment, a long contractual right of use, a secondary resale market and, in some circumstances, the ability to generate income when the owner is away. At the same time, entire marina businesses have attracted infrastructure funds and private-equity investors prepared to spend billions acquiring networks of waterfront assets whose principal economic product is something deceptively simple: somewhere to park a boat.
The reason is not that a strip of water has suddenly become intrinsically valuable. It is that the supply of the right strips of water has become extraordinarily difficult to increase.
A superyacht can move almost anywhere, but it cannot necessarily stay anywhere. The Mediterranean contains thousands of ports and marinas, yet the number capable of comfortably accepting a 60, 80 or 100-metre yacht in a location the owner actually wants to use is much smaller. The yacht needs sufficient depth, manoeuvring room, suitable mooring infrastructure, shore power, security, access for provisioning and crew, and ideally an airport close enough for owners and guests arriving by private or commercial aircraft. Add restaurants, hotels, shipyards, yacht agents and the social attraction of places such as the Côte d'Azur, Balearics, Italian Riviera, Sardinia, Greece or the Adriatic, and the pool becomes smaller again.
That scarcity is what begins to transform a practical necessity into something resembling an investment asset.
Land can be developed vertically. Offices can be added floor by floor, apartments can be built on previously unused sites and hotels can be extended. Prime marina capacity is far harder to manufacture. Coastlines are finite, suitable protected water is limited and new marina developments can involve environmental approvals, public concessions, dredging, breakwaters, planning restrictions and enormous capital expenditure. Even when a marina is expanded, creating another berth for a 100-metre yacht is not the same as adding another space in a car park. The berth may require substantial manoeuvring water, exceptionally strong mooring infrastructure, high-capacity electrical supplies and a large section of valuable quay.
At the same time, yachts have become larger.
This creates an unusual market imbalance. A marina designed decades ago may contain hundreds of berths, yet only a handful may be genuinely suitable for today's largest yachts. The total number of berths can therefore be misleading. What matters to a 70-metre owner is not whether a marina has 800 spaces; it is whether one of perhaps ten suitable spaces is available when the yacht needs it.
Once owners begin competing for that scarce capacity, the economics change. Paying annually for whatever berth happens to be available may no longer feel sufficient. An owner who regularly cruises the western Mediterranean may want certainty that the yacht can return to Antibes, Monaco or another preferred base each season. The yacht itself may change, but the strategic value of having access to a desirable home port can remain.
This is where the idea of “buying a berth” becomes more complicated than the phrase suggests.
In many marinas, the purchaser is not buying a piece of seabed in the way someone buys freehold land. What is being acquired may instead be a long lease, concession-related right, licence or contractual guarantee of use, and the precise legal structure matters enormously. At Port Vauban in Antibes, for example, the current system for vessels over 13 metres uses Guarantee of Use Contracts rather than the older berth-lease structure. These contracts can secure berthing within a specified port zone for up to 21 years in return for a financial contribution, but the arrangement does not necessarily guarantee one permanently private physical berth.
That distinction is important because a berth can behave economically like property without legally being property.
An owner may pay a substantial capital amount upfront for a long-term berthing right and later transfer or sell the remaining term, subject to the contract and marina rules. The value of that right is influenced by location, yacht size, remaining duration, demand, annual charges and the conditions attached to transfer or rental. Brokerage listings for prime Mediterranean berths regularly illustrate the scale at which these rights are marketed, with suitable berths for large yachts sometimes carrying multimillion-euro asking prices.
For an owner accustomed to treating berthing as an annual expense, paying millions for the right to berth a yacht can initially seem irrational. The calculation looks different, however, when the yacht is expected to remain in the same region for many years.
Suppose the owner knows that Antibes, Monaco, Palma, Porto Cervo or another established yachting centre will remain central to the family's cruising. Securing a long-term berth can provide something annual rental cannot always guarantee: certainty. The captain knows where the yacht will return after the season. Crew have a stable base. Cars, storage, contractors and provisioning arrangements can be organised around one location. The owner does not begin every year wondering whether a suitable berth will be available during the busiest months.
That certainty itself has economic value.
It can also affect the yacht. A highly desirable home berth may make ownership easier, and in some circumstances a purchaser selling a yacht may find that access to an attractive berth adds practical appeal to the overall proposition, even where the berth and yacht must be transferred as legally separate assets. For owners with several yachts over time, the berth may actually outlast any individual vessel. The first yacht is sold, another is ordered, yet the strategic foothold in the marina remains.
This is where the comparison with property begins to appear, but it needs to be treated carefully.
A berth with a fixed expiry date is not necessarily comparable with freehold real estate. If somebody acquires a contractual right ending in 2041, time is continuously being consumed. In simple terms, the buyer today is acquiring more years of use than the buyer several years from now. Unless scarcity and market demand rise enough to compensate, the shortening contractual term can place downward pressure on value.
A berth can therefore be both scarce and a wasting asset.
This is one of the most important distinctions for anyone thinking of a berth purely as an investment. A marina address may be prestigious, demand may be strong and comparable berths may rarely become available, but none of those things removes the legal expiry date. The investor must understand exactly what survives at the end of the contract, whether there are renewal rights, whether compensation exists, what approvals are needed for transfer and what annual charges continue during ownership.
The headline purchase price is only the beginning.
There may be annual marina charges, maintenance contributions, utilities, local taxes or fees, transfer costs and contractual obligations associated with the right. Some arrangements may permit the berth to be rented when the holder is not using it; others may place restrictions on subletting or require rental to be handled through the marina operator. The value of potential rental income therefore depends not simply on whether another yacht wants the berth but whether the contract actually allows the holder to monetise that demand.
Where it does, the economics become particularly interesting.
Many yacht owners use their vessels seasonally. A yacht may cross the Atlantic, enter a shipyard, spend winter elsewhere or cruise continuously for months. That can leave a valuable home berth temporarily empty. In a high-demand marina, allowing another yacht to use that space can turn an ownership cost into a partial income stream. The owner retains the strategic benefit of long-term access while potentially recovering part of the carrying cost during periods when the berth would otherwise sit unused.
That does not automatically make every berth a good investment. Occupancy fluctuates, rental rates vary, management charges apply and large yachts have very specific dimensional requirements. A nominal 60-metre berth is not necessarily interchangeable with every other 60-metre berth. Beam, draught, access, manoeuvring space and mooring configuration can determine which yachts can actually use it.
Yet those same limitations can reinforce scarcity.
A well-positioned berth that can genuinely accommodate larger yachts may be difficult to replicate. It cannot simply be moved to another part of town. A restaurant can open across the street from another restaurant; a hotel can be constructed a few kilometres away. Nobody can easily create another deep-water superyacht basin in the centre of an established Mediterranean destination.
That geographical exclusivity is one reason marina infrastructure itself has attracted increasingly serious financial investors.
The clearest evidence is no longer found only in individual berths being marketed for six- or seven-figure sums. It can be seen in the ownership of entire marina platforms. In February 2025, Blackstone Infrastructure agreed to acquire Safe Harbor Marinas, then described as the largest marina and superyacht-servicing business in the United States, in a transaction valued at $5.65 billion. At the time, Safe Harbor owned or operated 138 marinas across the United States and Puerto Rico.
The trend has continued. In July 2026, CVC agreed to sell D-Marin to infrastructure investor InfraVia Capital Partners. D-Marin operates a premium marina network spanning nine countries, placing a business built around waterfront infrastructure and recurring yacht demand firmly within the type of asset class being pursued by major institutional investors.
Other transactions point in the same direction. Antin Infrastructure Partners agreed in 2025 to acquire Aquavista, the UK's largest marina infrastructure provider, with 32 inland and coastal marinas and more than 5,300 berths at the time of the announcement. In Italy, infrastructure investor F2i was awarded a 50-year concession for the tourist port of Lavagna in January 2026, accompanied by plans for €75 million of investment.
These investors are not buying marinas because they particularly enjoy watching yachts arrive.
They are interested in the characteristics behind them.
A well-located marina has finite physical capacity and can generate recurring revenue from berthing, services and associated commercial activity. Customers may remain for years. Larger yachts require increasingly sophisticated facilities and tend to generate significant spending beyond the berth itself. Prime sites are difficult to reproduce and, in many jurisdictions, the right to operate them depends on long concessions or other arrangements that can create relatively predictable operating horizons.
The berth, viewed from this perspective, begins to resemble a small unit within a much larger piece of infrastructure.
For the individual yacht owner, however, the motives for acquiring a berth can be very different from those of an infrastructure fund. The owner may care less about yield calculations and more about knowing that when the yacht turns towards the Côte d'Azur in May, it has somewhere to go.
That emotional and practical value should not be underestimated.
Superyacht ownership is filled with uncertainty. Weather changes itineraries, shipyards delay refits, crew rotate, maintenance plans evolve and popular destinations become crowded at exactly the time everyone wants to visit them. A permanent or long-term home-port arrangement removes one recurring uncertainty from the operation.
For some owners, that is enough to justify the cost even if the berth never produces a conventional investment return.
For others, the calculation becomes more strategic. They may look at long-term yacht growth and conclude that high-quality large-yacht berths will become increasingly difficult to obtain. They may expect a waterfront destination to improve as restaurants, hotels and residential developments are added. They may believe the remaining contractual right can later be transferred at an attractive value, or that rental income will offset part of the cost of ownership.
Sometimes those assumptions prove correct.
Sometimes they do not.
A fashionable marina can lose appeal. A new competing development may open nearby. Regulations can change. Annual charges can increase. A redevelopment may alter the character of the port. Most importantly, a contractual right with a fixed end date continues getting shorter regardless of what happens to the surrounding property market.
This is why buying a berth should never begin with the assumption that “prime waterfront always goes up”.
The first question should be: What exactly am I buying?
Is it freehold ownership, a lease, a concession-linked right, shares in a marina company, a licence or a guarantee of use? How long does it last? Can it be sold freely? Can it be inherited? Can a company own it? Can it be rented to third parties? Does the marina retain control over which physical berth is allocated? What happens if the yacht becomes larger? What annual charges apply? What rights remain when the underlying concession expires?
Two opportunities described casually as “berths for sale” can have completely different legal and financial characteristics.
The marina itself also matters as much as the paperwork. An investor may be tempted by a prestigious address, but yacht owners use infrastructure, not postcards. A berth becomes more desirable when the marina works operationally: good security, reliable power, deep water, easy manoeuvring, strong shore services, competent staff, nearby technical support and convenient airport access. The presence of restaurants and luxury boutiques may enhance the destination, but the captain still needs to get the yacht safely alongside and keep it functioning.
This is one reason integrated marina destinations have become so powerful. Porto Montenegro, for example, combines large-yacht berthing with residential, hospitality, retail and crew infrastructure and advertises capability for some of the world's largest yachts. The marina becomes part of a wider destination rather than simply a place to connect shore power.
Once that happens, the economics of the waterfront begin feeding one another. Attractive marinas bring yacht owners and guests. Those visitors support restaurants, hotels, retail and property. Better amenities make the marina more desirable. Greater demand for berths supports further investment in the waterfront.
The berth is no longer merely where the yacht is parked.
It becomes an entry ticket to a particular location.
For superyacht owners, this explains why the best berths can sometimes appear absurdly expensive when measured simply by square metres of water. Their value is not determined by the water itself. It comes from scarcity, access, certainty and the infrastructure surrounding them.
The yacht might be worth €50 million and move anywhere in the world.
Yet on a Saturday afternoon in August, there may still be nowhere suitable to put it in the one place the owner actually wants to be.
That is the contradiction driving the berth market.
Yachts are mobile assets competing for immobile infrastructure.
As yachts have become larger, marina development more difficult and the most desirable destinations increasingly congested, control over that infrastructure has acquired financial value of its own. At one end of the market, an owner pays millions for a long-term right to keep a yacht in a particular port. At the other, some of the world's largest investment firms acquire entire networks containing thousands of berths.
Both are responding to essentially the same thing.
You can build another yacht.
Creating another Antibes, another Monaco or another naturally protected harbour in the right place is considerably harder.
That is why the humble marina berth has evolved from an annual operating expense into something owners, brokers and institutional investors increasingly examine as an asset.
But the smartest buyers understand one final distinction.
They are not really investing in a rectangle of water.
They are investing in the right to occupy a scarce piece of waterfront infrastructure for a defined period of time.
And the value of that right depends entirely on how scarce, secure and transferable it really is.
