Why the World's Largest Archipelago Has So Few Marinas

A marina by itself is not complicated infrastructure. It is a protected water body with berths, shore power, water, fuel, and waste disposal. Dozens of countries with a fraction of Indonesia's coastline, a fraction of its marine traffic, and a fraction of its government resources have built networks of them.

Indonesia has, until this year, had effectively none.

Understanding why is not a story about incompetence or indifference. It is a story about policy sequencing, institutional incentives, and the specific type of capital that marina development requires. Getting that story right matters, because the same analysis that explains the gap also points to what closes it.

The scale of what's missing

Let's establish the numbers precisely before diagnosing the cause.

Croatia, a country with approximately 5,800 kilometres of coastline inclusive of its islands, has built 85 marinas and 226 nautical ports generating EUR 180 million in direct port revenue in 2024, employing 2,042 people in nautical port operations alone, and contributing to a total tourism economy worth EUR 15 billion annually.

Monaco, 2 square kilometres, 39,000 residents, generates EUR 1.8 billion in maritime sector revenue, of which EUR 567 million flows directly through the yachting sub-sector.

Singapore, 700 square kilometres with no meaningful natural marine assets, has approximately 60-65 superyacht-capable berths across its marina network, and its maritime sector contributes more than 6% of GDP and supports around 140,000 jobs.

Indonesia, 17,504 islands, 95,000 kilometres of coastline, the Coral Triangle, the Ring of Fire, opened its first serious superyacht marina facility in 2025. One facility. After decades of stated commitment to marine tourism as a national development priority.

The government's own planning target in 2019 was 100 marinas. The gap between that target and the current reality is not a matter of degree. It is a matter of kind.

Why the gap exists: the concession problem

The most precise explanation for Indonesia's marina deficit is structural, not political.

Marina development requires long-term certainty. A marina is a capital-intensive infrastructure investment, tens to hundreds of millions of dollars depending on scale, that generates returns slowly, over decades, as marine traffic builds around it. The investment model is fundamentally dependent on a clear, stable, and legally enforceable right to develop and operate the facility for long enough to recover the capital and generate a return.

In most jurisdictions, that right is established through a concession: a government-granted licence to develop and operate on a defined water body for a fixed, commercially viable term. In Croatia, the concession framework for nautical ports is established in national legislation and administered consistently by the Ministry of Sea, Transport and Infrastructure. In Monaco, the Port Authority's arrangements with the state are perpetual and unambiguous. In Singapore, Marina Bay Sands and the leisure marina operators have clear, long-term licensing arrangements with the Maritime and Port Authority.

In Indonesia, the concession framework for private marina development has historically been complex, multi-agency, and inconsistently applied. Development on the coastline and on water bodies touches the jurisdictions of the Ministry of Marine Affairs and Fisheries, the Ministry of Transportation, the Ministry of Environment and Forestry, and in many cases local government. A developer pursuing a marina concession has needed to navigate a multi-ministry approval process without a clearly defined single pathway, without consistent precedent from previous successful approvals, and without predictable timelines.

Without a clear concession pathway, institutional capital cannot underwrite the development. Without institutional capital, the marina doesn't get built. Without the marina, the traffic doesn't materialise. Without the traffic, there's no proof of concept that persuades the next investor. This is not a capital shortage problem. It is a legibility problem: the risk-return profile of Indonesian marina development has been illegible for institutional investors because the enabling condition, a clear, enforceable right to operate, was not demonstrably available.

What the Bali Gapura Marina actually means

Indonesia's first serious superyacht marina is under construction at Benoa, Bali, 50 berths for vessels to 90 metres, developed jointly by Marina Development Indonesia and Pelindo (PT Pelabuhan Indonesia) under a 50-year government concession, with pilot operations beginning in late 2025.

The 50 berths matter. They matter far less than what the development proves.

It proves that a 50-year concession framework with Pelindo as co-developer is achievable. It proves that the multi-agency approval process can be navigated to a successful outcome. It proves that institutional capital will commit to Indonesian marina development when the concession pathway is clear. And it proves that the government, through Pelindo's willingness to participate as co-developer, is prepared to use state infrastructure capacity as an enabling mechanism for private marina development rather than a competitor to it.

Pelindo's stated position following the Bali Gapura development is that it is open to exploring additional world-class marinas across the Indonesian archipelago. That is the sentence that changes the investment thesis for the sector.

The geography that the gap leaves unexploited

The Bali Gapura Marina is in Benoa, Bali. Bali is the most accessible, most developed, and most commercially established destination in Indonesia. It is the logical first location for Indonesia's first serious marina, and its development there is genuinely significant.

It is also roughly where the interesting geography begins, not where it ends.

The Flores arc, Lombok, Sumbawa, Komodo, Flores, runs east from Bali through some of the most remarkable marine territory on earth. The Banda Sea and the route to Ambon and the Banda Islands. The passage north through the Maluku Sea toward Raja Ampat, widely considered among the world's pre-eminent diving and superyacht cruising destinations. The entire eastern Indonesian arc, from Komodo to the Bird's Head Peninsula, represents a passage of approximately 1,500 nautical miles through the highest marine biodiversity zone on the planet.

That passage currently has, in terms of superyacht-grade marina infrastructure, almost nothing. Vessels transiting it carry everything they need or divert to Lombok or Darwin for resupply. There is no provisioning node between Komodo and Raja Ampat. There is no haul-out capability for vessels above 30 metres east of Bali. There is no crew-change infrastructure at remote nodes, a significant operational constraint for vessels on 90-day passages.

The marina gap is not a Bali problem. It is an eastern Indonesia problem. And eastern Indonesia is, by any objective measure of marine tourism assets, the most important geography in the sector.

What closing the gap requires

The Croatia model is the most instructive precedent, and it contains an important lesson that is often missed: no single marina created the Croatian market. The network did.

Croatia's 85 marinas and 226 nautical ports did not appear at once. They were built sequentially, with each facility generating the traffic and the proof-of-concept that justified the next. Marinas were built ahead of demand in strategic locations, not as a response to existing volume, but as the infrastructure that created volume by making a destination navigable.

The same logic applies to Indonesia. The question is not whether to build a marina at Benoa. That decision is made. The question is what comes next, in what sequence, and whether the concession framework that enabled the Benoa development can be replicated across the strategic nodes of the eastern Indonesian arc.

That sequence, Benoa, then a node in the Sumbawa-Komodo corridor, then a facility at or near Labuan Bajo, then the approach to Raja Ampat, would create, for the first time, a navigable circuit for superyacht-grade vessels through Indonesia's most extraordinary waters. Not a destination with a marina. A circuit with a network.

That is what turns a facility into a legitimate market.
