Port Hercule (Monaco)

The approach and what lies inside

Port Hercule cuts into the Condamine, the flat ground between the old town on the Rock and the towers of Monte-Carlo. The approach is open and unobstructed from seaward and the harbour is entered between the head of the Digue Rainier III and the lee breakwater, with no bar, no channel and no tidal gate to time. Depths are extraordinary for a Mediterranean harbour. The port entrance carries around 40 metres, the outer pier around 30, and the inner basin runs from 2.5 metres at the shallow end to 55 metres in the deepest part, so draught is almost never the constraint.

The one historic weakness was swell from the eastern sector, which used to push straight into the basin. Studies begun under Prince Rainier III led to the semi-floating dyke that now closes that side, a 352 metre structure of about 160,000 tonnes cast at the foot of the Rock of Gibraltar and towed in. It was completed in 2002 and works with a 145 metre lee breakwater. The extra water it created carries a run of berths for yachts of 35 to 60 metres plus two positions of around 100 metres opposite the Yacht Club de Monaco building.

What the basin actually holds

Monaco's port authority quotes 760 berths across Port Hercule. Around 110 of those are sized for yachts over 24 metres, and roughly 30 are held back for visitors, subject to availability. The largest yachts lie along the outer walls where the water is deepest, and the private craft of the principality fill the inner quays. The biggest single berths are usually quoted at 130 to 135 metres, and the outer pier is built to take cruise ships of up to 300 metres, which gives some sense of the water depth involved.

Berthing is stern-to at almost every position, on lines run to rings in the quay wall with laid moorings forward. Beam is rarely the limiting factor here because the quays are long and the water deep. What limits an owner is the queue. Availability in season is best described as effectively closed for anything above 40 metres unless a berth is arranged months out or bought in through an agent working the visitor allocation.

Monaco does not sell berths and never has, which is the first thing an owner needs to understand about this harbour.

How a berth is obtained, and why one cannot be bought

This is the point that catches new owners out. Berths in Monaco are not property. The Principality funded its own harbour works and did not sell concessions to finance them, so every berth remains state-held and is let, never sold. Nothing in Port Hercule or Fontvieille comes onto the open market the way a lease on the Antibes breakwater does. Anyone offering a Monaco berth to buy is offering something that does not exist.

Annual berths are allocated by the harbour master on availability, yacht size and the applicant's residency status, with priority running to Monegasque nationals first and Monaco residents second. Waiting lists run to years and a non-resident application is often not considered at all. Short stays and event weeks work differently and are handled as advance requests reviewed by the port, with confirmations that stay provisional until close to arrival and repositioning to a nearby anchorage treated as a normal outcome. The practical route for a non-resident owner is a broker or agent with standing relationships at the port office.

What it costs and what it is priced on

Pricing is by length, by season and by position, and the position element is unusually large here because a trackside berth is a commercial asset for the week of the Grand Prix. Race pricing is zoned. Zone 1 is trackside, Zone 2 sits around the swimming pool, Zone 3 has no view of the circuit, and Fontvieille across the headland is cheaper again. For the 2026 Grand Prix, press reporting put a 50 to 59 metre yacht in the best trackside position at about EUR 110,135 for the week, with the smallest category under 19.5 metres at about EUR 22,316.

Away from race week the numbers are more ordinary but still at the top of the market. A 2026 Monaco cost guide put an annual berth for a 20 metre yacht at roughly EUR 25,000 to EUR 35,000 and superyacht annuals above EUR 100,000, with 50 metre-plus yachts from about EUR 1,500 a night before event loading. Treat those as indicative and dated to 2026. The comparison worth making is Cala del Forte at Ventimiglia, which Monaco Ports owns and where a berth concession genuinely can be bought, quoted at around EUR 1.6 million for a 35 metre position in the same reporting.

Power, fuel, waste and what the port supplies

Fresh water and electricity at 220V and 380V are run to the quays and pontoons. Fuel is taken at the BP station on the landing stage inside the port, which removes the delivery-barge dance that some Riviera ports require. Grey water collectors are fitted on selected quays and black water is pumped by contracted specialist companies, so that is a call the crew makes ahead of arrival. Shore facilities run to a dozen showers, twenty WCs, refuse collection and subscription wifi.

For an owner the more useful fact is what sits within walking distance. Monaco carries a dense bench of marine trades, agents and provisioners in a state of two square kilometres, and the port office actively coordinates movements because the basin is too tight to leave to chance. Serious refit work still goes elsewhere, most often to La Ciotat, Genoa or Palma, since Monaco has no yard capable of hauling a large yacht. Day-to-day attention can be handled without moving the boat.

Privacy, and the fact that there is none

Monaco is one of the most heavily policed and surveilled square miles in Europe, and that reassurance is a real part of what the berth buys. Crime against a yacht or its guests is close to a non-issue. Access to the quays is controlled and the port office knows every movement in the basin.

Privacy from the public is a separate matter. Restaurant terraces, hotel rooms and the Boulevard Albert 1er look straight down onto the water from close range, the quays are a public promenade for much of the year, and during show and race weeks the yacht is photographed continuously from a few metres off the passerelle. An owner who wants the boat unseen should not take a berth here.

Ashore, and getting to it

The harbour is the middle of the town. The Casino square, the Hotel de Paris and the Yacht Club de Monaco are within a short walk of the quays, and the banking and family-office cluster that many owners deal with sits in the same few streets. For a week with family the constraint is that Monaco is small and built up. There is one usable beach at Larvotto, the Oceanographic Museum and a good deal of shopping, and after four or five days most families want the tender or the car.

Access is the strongest argument for the port. Nice Cote d'Azur is the closest airport with long-haul and private-jet handling, and Monacair runs a scheduled helicopter shuttle from there to the Monaco heliport at Fontvieille in seven minutes, roughly every half hour from early morning. The road transfer is around 30 kilometres and unpredictable, sometimes over an hour in summer traffic. Italy is twenty minutes east and Saint-Tropez is a comfortable morning's run west.

When to be there and when not

Two weeks dominate the year. The Formula 1 Grand Prix, which in 2026 moved out of its traditional May slot to 5 to 7 June, packs the harbour rail to rail along the circuit quays and rewrites the port's rules for a fortnight either side. The Monaco Yacht Show follows on 23 to 26 September 2026, filling the basin with around 120 superyachts and the brokerage world that follows them. Both are effectively closed to anyone who did not arrange a place well in advance.

The workable weeks are the rest of the summer, June through to mid-September, when Monaco functions as a base for the Riviera and the Italian coast. Spring and late autumn are pleasant and quiet, and winter berthing is genuinely available at reduced rates because much of the fleet has gone to refit or across the Atlantic. The weather that ends a day here is an easterly, which builds a short sea outside the port and makes the coastal run east towards Italy unpleasant well before it troubles the basin itself.

The honest downside

An owner cannot own the asset. Everything an owner spends on a Monaco berth is rent on something the state can decline to renew, allocated under a system that puts nationality and residency ahead of the size of the yacht or the length of the relationship. For an owner used to buying his way to certainty, that is the hard part, and it is why so many have quietly taken concessions at Ventimiglia instead and accepted the fifteen-minute shuttle.

The rest of it is crowding and cost. The basin is tight, movements are choreographed, wash from the constant traffic makes the inner berths lively, and in peak weeks the yacht becomes public scenery. Event prices have risen sharply since 2019. Most owners who want calm pair a Monaco berth with a quieter home port.

The shore power on the Rainier III dyke, in numbers

The port publishes what it built for mega yachts on the Digue Rainier III and the figures are unusually specific. Six shore power points deliver 410 V at 2,000 A, rated 1,250 kVA each, and a single high-voltage point delivers 6,600 V at 300 A, rated 3,400 kVA. The high-voltage position is the one to plan around, because a yacht taking it steps the supply down through her own transformer rather than plugging a standard cable, and it has to be arranged with the Capitainerie before arrival. Six units at 410 V and one at 6,600 V is also the practical measure of how many mega yachts the dyke can serve at once. All figures from the port's own superyacht infrastructure booklet, updated 20 March 2025.

Frequency is not stated anywhere in that booklet. Monaco sits on the European 50 Hz grid and the port advertises no 60 Hz supply, so a yacht built for 60 Hz converts on board. Running generators instead is not an option, because connection to shore power is compulsory at the dyke and discharge of sewage is prohibited. Fluids are metered rather than bundled, at EUR 0.4188 per kWh and EUR 6.2245 per cubic metre of fresh water, both with VAT included, on the March 2025 schedule. Two further port rules catch crews out. Radars must be switched off at the port entrance, and pilotage is compulsory for any movement inside the port by a yacht of 80 m or over.

The published tariff, and the winter number that matters more

Monaco publishes a passage tariff for Port Hercule outside the dyke, with VAT at 20 per cent already included. On the 2026 card a yacht of 50 to 54.99 m pays EUR 500.40 a day in low season and EUR 1,258.80 a day in high season, and a yacht of 60 to 64.99 m pays EUR 662.40 and EUR 1,549.20. High season runs 1 May to 1 October 2026, low season either side of it. The same card gives monthly rates of EUR 13,749.60 and EUR 25,207.20 for the 50 to 54.99 m band, and it runs in length bands all the way to 210 to 219.99 m. A multihull pays 60 per cent on top. Berths on the dyke itself are not on the passage card and are quoted by the Capitainerie.

The winter card is the one that shapes a season. Hivernage 2026-2027 covers 1 October 2026 to 1 May 2027 and is quoted as a single figure for the whole period, VAT included: EUR 97,456.80 for a 50 to 54.99 m yacht and EUR 116,722.80 for 60 to 64.99 m. Worked through, a 62 m motor yacht wintering at Hercule commits EUR 116,722.80 for the berth, then adds metered power at EUR 0.4188 per kWh and water at EUR 6.2245 per cubic metre on actual consumption, then adds the diver. Divers are chargeable to the yacht every time a dyke position has to slip and re-connect its ground lines so a neighbour on La Cloche can lift her anchor, which happens on someone else's schedule and not on the owner's.

The wind that empties the dyke, and the 8 m that is the real depth

Port operations have a published weather limit and it is asymmetric. For a yacht under 200 m on the Rainier III dyke, the threshold to remain alongside is Beaufort 10 with the wind off the land, which the port gives as 48 to 55 knots, and Beaufort 8 with the wind off the sea, 34 to 40 knots. Above either figure the port authority can require the yacht to leave the berth. It takes a full gale off the land to move a boat off the dyke and only a strong breeze off the sea, which is a plain statement of where the exposure lies. The sea wind here is the easterly, and it closes the coastal run east towards Italy long before it troubles the inner basin.

The depth figure that binds on the dyke is not the 30 m under the outer pier. The mooring system is dimensioned for winter conditions and works on four ground lines rated at 60 to 80 tonnes of horizontal traction, with concrete blocks and submerged buoys sitting at 15 m. Those lines must be held in tension for the entire stay, and the yacht is required to tell the Capitainerie if tension cannot be maintained, because the tension is what keeps 8 m of water clear above the lines. A diver sets marker buoys on the 8 m point when a yacht connects. A hull drawing more than that has a problem the headline harbour depths do not disclose. The fender wall she lies against runs to 22 units of 2,300 x 3,000 mm, 200 tonnes in total, rated at 299 kNm.

Who it is for: An owner who wants the boat at the visible centre of the Mediterranean season and can accept renting a berth he will never be allowed to buy.
