Monaco Superyacht Marinas: Berths, Maximum Length and Costs

Monaco has one of the most concentrated superyacht berth markets in the Mediterranean, but a request for “a berth in Monaco” can mean very different things depending on yacht length, season and the owner's priorities. Port Hercule is the Principality's principal large-yacht harbour, Port de Fontvieille is a smaller and more constrained basin, while Cala del Forte in nearby Ventimiglia expands the Monaco Ports network beyond the Principality itself.

The important numbers are not simply the total berth counts. For superyachts, the practical questions are how many positions can accept a yacht of a particular length and beam, what the published 2026 tariff is for that size, and whether a berth is actually available for the required dates.

Monaco's superyacht marina network at a glance

Monaco has two principal yacht harbours inside the Principality, with Port Hercule carrying the bulk of the large-yacht role. Cala del Forte is about 7.9 nautical miles away in Ventimiglia and is operated by Monaco Ports as a complementary marina, giving owners another way to remain closely connected to Monaco without occupying scarce space inside Port Hercule.

Those figures must be read carefully because a tariff band is not the same thing as a guaranteed berth. Beam, draught, berth geometry, manoeuvring room, weather, harbour operations and existing allocations can all reduce the number of positions that are genuinely usable by a particular yacht.

Port Hercule is Monaco's main large-yacht harbour

Port Hercule is the harbour most closely associated with Monaco's superyacht identity and the Monaco Yacht Show. The current Superyacht Guide marina record lists 760 berths, including 30 visitor berths, and records a 130-metre maximum yacht length for the directory profile.

The official 2026 outside-dike tariff, however, contains pricing bands all the way through 210 to 219.99 metres. That does not mean an ordinary 219-metre marina berth can be booked on demand; it shows that the published commercial schedule has provisions for vessels far beyond the size normally associated with standard marina allocation.

What does Port Hercule cost in 2026?

Ports de Monaco publishes separate low- and high-season passage prices for Port Hercule outside the dike, with high season running from 1 May to 1 October. The rates include the applicable 20% VAT and rise sharply once yacht length moves into the larger superyacht brackets.

A 50-to-54.99-metre yacht therefore moves from €500.40 per day in low season to €1,258.80 in high season, while a yacht in the 100-to-109.99-metre bracket is listed at €2,964 per day during high season. These are published passage rates, not a promise that a suitable berth will be available for every yacht in every size category.

Wintering in Port Hercule changes the calculation

Ports de Monaco also publishes a seven-month wintering schedule from 1 October 2026 to 1 May 2027. The rate is €48,114 for a 40-to-41.99-metre yacht, €97,456.80 for 50 to 54.99 metres, €116,722.80 for 60 to 64.99 metres and €136,762.80 for 70 to 74.99 metres.

At larger sizes, the seven-month figure reaches €158,611.20 for 80 to 84.99 metres, €213,506.40 for 100 to 109.99 metres and €261,309.60 for 120 to 129.99 metres. For an owner considering Monaco as a seasonal base, the berth therefore becomes a significant annual operating line rather than a simple nightly marina charge.

Fontvieille serves a different part of the fleet

Port de Fontvieille sits beneath the western side of the Rock and is a much smaller marina environment than Port Hercule. Superyacht Guide's current directory profile records a 30-metre maximum length, while the official 2026 tariff itself extends through the 38-to-39.99-metre bracket.

That difference is precisely why published tariff limits should not be treated as berth guarantees. A yacht may fall inside a price band yet still be unsuitable for the available berth because of its beam, draught, manoeuvring requirements or the geometry of the basin.

What does Fontvieille cost?

Fontvieille's 2026 passage pricing is considerably more compressed because it serves a smaller range of vessel sizes. A yacht between 24 and 25.99 metres is listed at €286.80 per day in low season and €304.80 in high season, with monthly rates of €4,996.80 and €6,406.80 respectively.

The seven-month 2026–27 winter tariff is €35,419.20 for 24 to 25.99 metres, €41,938.80 for 30 to 31.99 metres and €51,441.60 for 38 to 39.99 metres. Fontvieille can therefore be attractive for the lower end of the superyacht fleet, but size and berth geometry become increasingly important as a yacht approaches the upper end of the published schedule.

Cala del Forte expands Monaco's practical capacity

Cala del Forte is not inside Monaco; it is in Ventimiglia, Italy. It is nevertheless operated by Monaco Ports, lies only 7.9 nautical miles from the Principality and officially provides 180 berths for vessels from 6.5 metres up to 76 metres.

The marina materially changes the Monaco berth equation because it gives larger yachts an alternative when the owner needs rapid access to the Principality rather than a berth physically inside it. That distinction can be valuable during busy periods when suitable space in Port Hercule is scarce.

What does Cala del Forte cost in 2026?

Cala del Forte's published 2026 high-season daily rate is €484 for the nominal 40-metre category, €920 for the nominal 50-metre category, €1,350 for the nominal 60-metre category and €1,650 for the nominal 70-metre category. The corresponding high-season monthly figures are €9,930, €19,800, €25,800 and €28,700.

Its winter-season figures are €37,700 for the nominal 40-metre category, €74,800 for 50 metres, €95,300 for 60 metres and €111,800 for the 70-metre category. Water and electricity are charged according to consumption, so the berth tariff should not be mistaken for the yacht's complete port bill.

Standard tariffs are not major-event tariffs

The ordinary passage tables should not be used as a proxy for Monaco Grand Prix or Monaco Yacht Show economics. Major events involve exceptional allocation, security and harbour-management arrangements, and scarcity can become more important than the standard published nightly price.

This matters because a yacht that can obtain a conventional August berth may face a completely different commercial and operational environment during an event week. Captains and managers should therefore budget event periods separately rather than extrapolating from the ordinary seasonal tariff.

Which marina suits which yacht?

For yachts around 24 to 30 metres, Port Hercule and Fontvieille can both be relevant, depending on dimensions and availability. As yacht length rises through the 40-to-70-metre range, Port Hercule becomes the primary Monaco option while Cala del Forte provides an increasingly useful alternative nearby.

Above that range, the number of genuinely suitable positions contracts sharply even though Port Hercule's outside-dike tariff continues into very large yacht categories. For the largest vessels, advance coordination with Monaco Ports, the yacht's management team and local agents becomes part of the berth itself rather than an optional administrative step.

The real Monaco cost is scarcity

The published prices show that normal Monaco berthing is not automatically the largest cost in a superyacht's operating budget. Crew, engineering, maintenance, insurance, fuel and technical work can all outweigh the ordinary berth rate, especially when the stay is short.

What makes Monaco expensive in practical terms is scarcity: the owner may require a particular location, on particular dates, for a yacht whose dimensions fit only a small number of positions. Port Hercule may contain hundreds of berths, but a 90-metre yacht is not choosing from hundreds of interchangeable spaces.

That is why Monaco remains one of the clearest examples of the difference between total marina capacity and useful superyacht capacity. The headline price matters, but the more valuable commodity is a suitable berth in exactly the right place when the yacht needs it.
