The Stockholm Archipelago

Region

about 30,000 islands, islets and skerries running roughly 80 km east from Stockholm and 150 km north to south

Stockholm to Sandhamn, the centre of Swedish yachting, is about 25 nautical miles entirely in sheltered water

There is effectively no tide in the Baltic, only a few centimetres of wind driven variation

There is no ocean swell inside the archipelago, and the water is brackish rather than salt

Sea temperature reaches about 18 to 20 degrees in a good August and is colder either side of it

Season

effectively mid June to late August, and the archipelago empties in the third week of August

Allemansratten, the right of public access, allows free mooring in nature on shores that are not private

The local technique is bow to a rock with a stern anchor and a line ashore, and nature reserves have mooring rings set into the granite

Anchoring is forbidden at certain locations within Sandhamn, and the harbour asks boats to contact the tender or an attendant before mooring

The Royal Swedish Yacht Club runs guest marinas at Sandhamn, Lokholmen and Telegrafholmen for more than 400 boats

Sandhamn itself has about 150 guest moorings, open from the last weekend in April to the last weekend in October

There are around 60 guest harbours in the Stockholm area, and practically every sizeable inhabited island has one

Guest harbours provide water, power, showers and usually a restaurant, and are inexpensive by the standards of this directory

The islands to know

Vaxholm and its fortress, Grinda, Moja, Finnhamn, Uto in the south and Arholma at the northern end

Navigation is rock pilotage on marked fairways, where the charted line matters and a metre off it can be a rock

Large yachts lie on the central Stockholm quays at Strandvagen and Nybroviken by arrangement with the port, in front of the Grand Hotel

The Royal Swedish Yacht Club was founded in 1830 and is among the oldest yacht clubs in the world

The round Gotland race runs roughly 350 nautical miles from Stockholm around the island of Gotland and back

Midsummer, the weekend nearest the solstice, is the fixed point of the Swedish summer and the archipelago's busiest

Stockholm is at 59 degrees north, giving about 18 hours of daylight at midsummer and a twilight rather than a night

Air

Arlanda is the long haul gateway about 40 minutes north, and Bromma inside the city is the usual private aviation field

The Waxholmsbolaget archipelago ferries serve the islands year round, so guests can join a boat almost anywhere in the group

Sweden is in the EU but not the euro. The currency is the krona and card payment is close to universal

Sweden's standard VAT rate is 25 per cent, among the highest in the European Union

An archipelago that starts in the middle of a capital

The Stockholm archipelago runs roughly 80 kilometres east from the city to the open Baltic and about 150 kilometres from north to south, and it is usually counted at around 30,000 islands, islets and skerries. It thins as it goes: wooded islands with houses and jetties on the inside, bare pink granite and juniper on the outside, and the last skerries standing alone in the Baltic. Stockholm to Sandhamn, the yachting capital of the group, is about 25 nautical miles through sheltered water the whole way.

The distinguishing feature is that the cruising begins where the city ends. A boat can lie in the middle of Stockholm one evening and be anchored off bare rock the next morning without ever leaving protected water. Very few cruising grounds put a European capital and genuine wilderness that close together, and none of the others in this directory does it without a passage in between.

No tide, no swell, and almost no salt

The Baltic behaves unlike any other cruising ground in Europe. There is effectively no tide, a few centimetres of wind driven variation rather than a range, so a boat lies to the same depth all day and a rock is where the chart says it is. There is no ocean swell inside the archipelago, because the islands break it up before it arrives. And the water is brackish rather than salt, at a salinity a fraction of the Mediterranean's, which changes what grows on the hull and what a watermaker will do with it.

The compensations come with a price. The water is cold, around 18 to 20 degrees in a good August and colder either side of it. The season is short, effectively mid June to late August with shoulders at each end, and the archipelago empties abruptly in the third week of August when Swedish schools go back. And the granite is unforgiving: this is a rock strewn ground where the marked fairways matter, where a chart plotter is a working instrument rather than a convenience, and where a metre off the line can be a metre onto a rock.

Moor to a granite rock in a nature reserve for nothing, twenty five miles from a berth in front of the Royal Palace.

The right that changes how you cruise

Allemansratten, the Swedish right of public access, allows a boat to moor in nature, free of charge, on shores that are not private, and it is the reason the archipelago is cruised the way it is. The local technique is to go bow to a rock face with an anchor out astern, with a line ashore to a ring or a tree, which is why so many Swedish boats carry a bow ladder and why the nature reserves have mooring rings set into the granite. Nobody charges, nobody books and there is no marina involved.

That freedom sits alongside real restrictions in the busy places. At Sandhamn, anchoring is forbidden at certain locations, and the harbour asks that a boat contacts the tender or a harbour attendant before mooring rather than helping itself. Nature reserves have bird protection areas that are closed in the nesting season. The workable summary is that the outer archipelago is genuinely free, the popular islands are managed, and the difference is signposted rather than guessed at.

Sandhamn, and the sixty guest harbours

Sandhamn on Sandon is the centre of Swedish yachting and the home of the Royal Swedish Yacht Club, which runs guest marinas at Sandhamn, Lokholmen and Telegrafholmen for more than 400 boats, with about 150 guest moorings at Sandhamn itself. The marina opens from the last weekend in April to the last weekend in October. The village behind it is a pilot station turned sailing town, and in July it is the busiest small harbour in Sweden.

Around it there are some sixty guest harbours in the Stockholm area, and practically every inhabited island of any size has one. Uto in the south, Moja and Finnhamn in the middle, Grinda close in, Arholma at the northern end and Vaxholm on the way out of the city with its fortress in the channel. They provide water, power, showers and usually a restaurant, they are inexpensive by the standards of anywhere in this directory, and in the peak fortnight they fill by mid afternoon.

Where a large yacht actually goes

This is a ground built for boats of ten to twenty metres, and that is the honest starting point. The guest harbours are sized accordingly, the natural harbours are approached between rocks, and a deep draft closes off a great many of the best places. A yacht of 30 metres and more cruises the main fairways, anchors in the larger bays and works the archipelago by tender, which is a perfectly good way to see it but is not the way the place is designed to be used.

In the city itself, large yachts lie on the central quays by arrangement with the port, along the waterfront at Strandvagen and Nybroviken, in front of the Grand Hotel and within sight of the Royal Palace. It is one of the most spectacular city berths in Europe and it is arranged rather than booked. Checked in August 2026, no Stockholm marina publishes a superyacht rate card, and the practical route for anything of size is an agent.

The season, and the light

Stockholm sits at 59 degrees north, so midsummer gives around 18 hours of daylight and a twilight rather than a night, and the whole culture of the archipelago is built on those few weeks. Midsummer itself, the weekend nearest the solstice, is the fixed point of the Swedish calendar and the archipelago is at its fullest and its happiest. July is the holiday month. The first fortnight of August is warm and quieter, and after the third week the water empties and stays empty.

The weather is Baltic rather than Atlantic: generally settled in summer with sea breezes, but capable of a hard blow from any direction with very little warning, and thunderstorms in high summer that arrive quickly. Because everything is close, that is a nuisance rather than a hazard, and there is shelter within half an hour almost everywhere in the group. Outside the season the archipelago freezes, and icebreakers keep the commercial channels open through the winter.

The fixed week, and the racing

The Royal Swedish Yacht Club, founded in 1830, is one of the oldest yacht clubs in the world and it runs the racing calendar from Sandhamn. The offshore classic is the round Gotland race, roughly 350 nautical miles from Stockholm out into the Baltic, around the island of Gotland and back, and it is one of the largest offshore races in the world by entry. The regatta week at Sandhamn is the social fixture of the Swedish summer.

Beyond racing, the archipelago is a cruising rather than a spectating culture. There is no equivalent of Porto Cervo's Piazzetta or Cowes' waterfront, and the Swedish attitude to a large yacht is polite rather than impressed. An owner who wants to be seen is in the wrong sea. An owner who wants to swim off a granite slab at eleven at night in daylight has arrived.

Getting guests in

Stockholm Arlanda is the long haul gateway, about 40 minutes north of the city, and Bromma sits inside the city and is the usual field for private aircraft, a few minutes from the central quays. Both run full year schedules, and the Arlanda Express reaches the centre in twenty minutes. From the city, the archipelago boats of the Waxholmsbolaget serve the islands year round, which gives guests a workable way to join a yacht anywhere in the group without a helicopter.

Sweden is in the European Union but not in the euro, so the currency is the krona and card payment is close to universal, cash close to extinct. English is spoken to a standard that makes an interpreter unnecessary. Sweden's standard VAT rate is 25 per cent, among the highest in the Union, and the treatment of a charter depends on flag, place of departure and itinerary, so the structure belongs with a Swedish adviser before the boat arrives.

Ashore

Stockholm is built on fourteen islands and is one of the best looking capitals in Europe, with Gamla Stan's medieval core, the Vasa museum holding a warship raised whole from the harbour after 333 years underwater, the palace, and a restaurant scene that has been quietly excellent for two decades. The city quays put a boat inside walking distance of all of it. Guests who want a city and a wilderness in the same week can have both here more easily than anywhere else in this directory.

In the archipelago the shore side is deliberately small: a jetty, a summer restaurant, a shop, a sauna. Vaxholm has its fortress, Grinda and Finnhamn have their inns, Uto has a mine and a bakery, and Sandhamn has the yacht club and the hotel. The Swedish sauna and swim ritual is the actual entertainment, and guests either take to it immediately or spend a week explaining that they will try tomorrow.

The honest downside, and what is not published

The season is ten weeks and the water is 18 degrees in the best of them. The ground is built for boats a third the size of most in this directory, and a large yacht spends the fortnight on the main fairways with the tender working. Navigation is unforgiving rock pilotage rather than open water cruising. Sweden's standard VAT is 25 per cent. And after the third week of August the archipelago is beautiful, empty and closed.

Checked in August 2026, no Stockholm marina or guest harbour publishes a superyacht rate card, and none publishes a fuel price. The city quay berthing that large yachts use is arranged through the port and the agents rather than tariffed publicly. The guest harbour fees are published locally and vary island by island with no consolidated table. And nothing published tells an owner how many of Sandhamn's 150 guest moorings are free on a Friday in July, which is the number that decides the weekend.

Pour qui: An owner who wants wilderness and a capital city in the same week, is content with a boat under about 30 metres or with running tenders from the fairways, and does not mind that the whole thing lasts ten weeks.
