The Atlantic circuit — the clockwise loop that takes a European sailing boat from the UK or northern Europe down the Iberian coast, through the Canary Islands, across the Atlantic to the Caribbean, north to the US East Coast or Bermuda, and back across the North Atlantic to the Azores and home — is the offshore sailing journey that a particular type of cruising sailor spends years working toward. It is not technically demanding in the way that a Cape Horn rounding is demanding; the trade wind passages that form the Atlantic circuit's core are among the most forgiving offshore routes in the world. But it requires planning, preparation, and financial commitment at a level that separates the sailors who complete it from the sailors who talk about it.
This guide is written for European sailors who are past the conceptual stage and working on the specifics: the timing, the routing choices, the realistic costs, the rally options, and the mistakes that first-time circuit sailors make with enough regularity to constitute a pattern worth naming.
The Classic Clockwise Circuit
The canonical clockwise Atlantic circuit follows the seasonal wind patterns that have been exploited by ocean-going vessels since the age of sail: south with the northeast trades in autumn and winter, west across the Atlantic on the reliable trade wind belt, north through the Caribbean and up the US East Coast in spring, and east back across the North Atlantic on the summer westerlies via the Azores. Sailing with these patterns, rather than against them, is what makes the circuit feasible in a moderate cruising boat.
The departure from the UK is dictated by the Biscay autumn window. The Bay of Biscay is a significant piece of water — 400 miles of exposed ocean from Ushant to the Spanish corner at Finisterre — and its autumn weather is unpredictable, with depressions tracking east across it on a roughly weekly cycle in October and November. The window strategy is to leave UK waters in September or early October, when summer high pressure still offers some stability, and time the Biscay crossing for a settled spell. Most circuit boats make the UK to Portugal or Spain leg in stages: Falmouth or Plymouth to La Coruña or Vigo on one weather window, then south to Lisbon or the Algarve ports (Lagos, Vilamoura) at leisure.
From Portugal, the run to the Canaries is typically timed for October or early November. The passage from Lisbon or Lagos to Gran Canaria or Lanzarote is roughly 1,200–1,300 miles, often coastal (Cascais, Madeira, then the final run to the Canaries) or sometimes direct offshore. By the Canaries, most circuit boats are in place by late October or early November, which puts them in position for the ARC departure at the end of November from Las Palmas de Gran Canaria.
Timing the ARC and the Atlantic Crossing
The Atlantic Rally for Cruisers departs Las Palmas, Gran Canaria, in the last week of November — typically around 22–25 November — and arrives in Rodney Bay, St. Lucia, two to three weeks later depending on boat speed and conditions. The crossing covers approximately 2,700 nautical miles in the northeast trade winds, which are typically well-established at Gran Canaria's latitude (28 degrees north) by late November. The passage itself is almost universally described by first-time ocean crossers as more enjoyable than anticipated: consistent winds, warm temperatures, a straightforward downwind or broad reaching course, and the social dynamic of hundreds of other boats on the same route.
The ARC is not the only crossing option. Independent boats cross in November and December without joining the rally, following the same basic route. The RORC Transatlantic Race departs from Lanzarote in January and targets Grenada — a faster boat race rather than a cruising rally, but one that independent cruisers have used as a social structure for a non-ARC crossing. Boats that choose to stop in Cape Verde before crossing — picking up the trades at 17 degrees north rather than 28 — can also cross on the Cape Verde to Caribbean route, typically December or January.
The Caribbean Season and the Hurricane Window
The Caribbean cruising season runs from December through May. The trade winds are reliable, the weather is settled, and the anchorages between the Windward Islands and the Virgin Islands fill with the circuit fleet arriving from their Atlantic crossings. This is when the Caribbean does what it is famous for: consistent 15–20 knot trades, crystal water, anchorages shared with a global community of offshore sailors, and the infrastructure of the charter and cruising industry to support it.
Hurricane season runs from June 1 through November 30, with the statistical peak in August and September. The circuit sailor's calendar is built around this window: arrive in the Caribbean in December, complete the island chain over the following months, and make a clear decision about where to be when hurricane season begins. The options are: leave the Caribbean entirely (north to the US East Coast, Bermuda, and across to the Azores before June); move the boat south to below the hurricane belt (the ABC islands — Aruba, Bonaire, Curaçao — are technically below the statistical hurricane track, but no location in the Caribbean is categorically safe); or leave the boat in a reputable hurricane hole or boatyard and fly home. Each option has its proponents and its risks; the worst choice is the one that is not made consciously.
The Northbound: USA, Bermuda, and the Azores
The northbound return from the Caribbean to Europe exploits the summer westerlies that establish themselves across the North Atlantic as the Azores High migrates north and east. Most circuit sailors leave the Caribbean in April or May, working up the island chain toward Puerto Rico and the Dominican Republic, then north to Bermuda — roughly 950 miles north of the Virgin Islands — for the Atlantic crossing preparation. Bermuda is an excellent staging port: excellent marina infrastructure, full chandlery and boatyard capability, a well-established Atlantic crossing community in May and June, and a position at 32 degrees north that is well placed for the westerly window.
From Bermuda to the Azores is approximately 1,800 nautical miles east-northeast, typically taking ten to fifteen days. The passage often begins with a beat into residual westerlies before finding the summer high-pressure pattern that allows a more comfortable broad reach for the last third of the passage. The Azores — Horta on Faial in particular — is the spiritual climax of the Atlantic circuit: every offshore sailors' gathering point in the North Atlantic, the famous wall at Peter's Café Sport covered with the plaques and burgees of boats that have made the crossing, a landfall that confirms the completion of the circuit's hardest leg. From the Azores, the final 1,200 miles home to the UK is typically a straightforward summer passage on westerlies or southwesterlies.
The Anticlockwise Option
The anticlockwise circuit — east to west across the North Atlantic direct from Europe or the Azores to North America, then south down the US East Coast, through the Bahamas to the Caribbean, and back east via the trade wind belt toward the Canaries or Azores — is technically possible and occasionally done, but it is the harder direction for a number of reasons. The North Atlantic westerlies, which deliver the clockwise sailor comfortably home from the Azores, work directly against the anticlockwise sailor trying to reach North America from Europe. The crossing from the Azores or Ireland to Nova Scotia or Newfoundland is an upwind or close-reaching passage in variable and often unpleasant North Atlantic weather. The routing is possible — many boats have done it — but it takes longer, is less comfortable, and offers no particular advantage over the clockwise direction that the wind patterns support naturally. Most experienced offshore sailors choose the clockwise circuit unless they have a specific reason to approach North America from the east.
Budgeting the Circuit
The circuit is expensive. The two most common mistakes in planning are underestimating the boat preparation cost before departure and underestimating the annual maintenance cost while cruising. A realistic budget for a European sailor completing a full clockwise circuit — UK to Caribbean and back — over 18 months to two years, with a suitable bluewater cruising boat already purchased, runs to £50,000–£100,000 depending on the style of the trip, marina usage, flights home, and what breaks.
The 10% rule — budget 10% of the boat's value per year for maintenance and operating costs — is a reasonable starting point for boat-specific costs. A £150,000 offshore cruising boat will cost approximately £15,000 per year in insurance, maintenance, repairs, and equipment, not including marina fees, fuel, or provisioning. Marina fees along the circuit are highly variable: the Canaries are reasonable (€20–40 per night for a 40-footer), the Caribbean is expensive (US$60–100 per night in the BVI and USVI; cheaper in the Windwards), Bermuda is expensive (US$100+ per night), and the Azores and Portugal are again reasonable by European standards.
The ARC entry fee for a 40-foot boat is approximately €3,000–4,000 and includes some services in Las Palmas and St. Lucia; independent crossers save the fee but miss the social infrastructure. The World ARC — the round-the-world organized circuit — runs to substantially higher figures, with entry fees of €15,000–25,000 for the full circumnavigation. Budget the circuit honestly before you go; underestimating the financial commitment is the single most reliable predictor of a truncated circuit.
Rally Options
The Atlantic Rally for Cruisers (ARC), organized by the World Cruising Club, is the largest ocean sailing rally in the world and the one that most first-time circuit sailors use for their Atlantic crossing. Its advantages are well-documented: organised fleet, weather briefings, safety net of other boats on the same route, port arrival support in St. Lucia, and a social programme that makes the Caribbean arrival a genuine event. Its disadvantages are equally real: the ARC's late November departure is dictated by the organiser's schedule, not optimal weather analysis; the fleet size means Rodney Bay is crowded on arrival; and the structure of a rally can feel constraining for sailors who prefer to make their own decisions.
The ARC PLUS is the Cape Verde variant — departing the Canaries, stopping in Cape Verde for approximately a week, then crossing to St. Lucia. The Cape Verde stop is an excellent addition for sailors who want to extend the southbound leg and experience the archipelago in a structured context. The RORC Transatlantic Race departs Lanzarote in January for Grenada — a competitive race rather than a rally, but followed by independent cruisers who want a January crossing. The World ARC is the circumnavigation rally, operating on a two-year cycle with a full-circuit itinerary that includes the South Pacific, Indian Ocean, and South Africa; it is genuinely global in scope and priced accordingly.
The Most Common Mistakes
After decades of circuit sailors arriving in the same places at the same times, the patterns of error are well-established. Leaving the UK too late is the most common: a boat that departs UK in late October is rushed to the Canaries for the ARC, has no margin for delay or mechanical trouble, and arrives at every stage with less time than it wanted. The window for comfortable circuit departure is September; October is acceptable; November is already a scramble.
Underestimating the boat is the second consistent problem. The Atlantic circuit is not technically extreme, but the distances involved mean that anything marginal — a worn rigging component, an ageing impeller, a diesel injection pump that "has been making a noise but seems okay" — will find a way to fail at sea, in a position where the nearest help is a day's sail away. The circuit-standard practice is to replace all questionable components before departure, not to save money by hoping they hold. The cost of a new impeller at the dock is trivial compared to the cost of drifting in the Canaries with an overheated engine.
Failure to plan the hurricane season exit is the third perennial error. Sailors who arrive in the Caribbean in December with no plan for what to do in June consistently find themselves scrambling in May — either rushing north in suboptimal weather to make Bermuda before hurricane season, or leaving a valuable boat in an arrangement that was planned in two days rather than two months. The hurricane question should be answered before you leave the UK, not on arrival in Antigua.

Frequently Asked Questions
When should a UK boat depart to start the Atlantic circuit? The ideal departure window is September, with October acceptable but already compressed. A boat leaving UK in late October has no margin for mechanical delays before the ARC's late November start from Las Palmas. The Bay of Biscay crossing strategy is to time the passage for a settled weather spell, typically staging through Falmouth or Plymouth to La Coruña before heading south.
How far is the ARC crossing and how long does it take? The Atlantic Rally for Cruisers covers approximately 2,700 nautical miles from Las Palmas, Gran Canaria, to Rodney Bay, St. Lucia. Most cruising boats complete it in two to three weeks, with typical passage times of 18–21 days. The crossing runs in the northeast trade winds, which are usually well-established at Gran Canaria's latitude of 28°N by late November.
What are the hurricane season options for Atlantic circuit boats? Hurricane season runs June 1 through November 30 with the statistical peak in August and September. The three options are: leave the Caribbean entirely by heading north to Bermuda and then to the Azores before June; move the boat south to the ABC islands (Aruba, Bonaire, Curaçao) below the main hurricane track; or leave the boat in a reputable hurricane hole or boatyard and fly home. Each choice has advocates and risks — the worst outcome is no deliberate plan.
What is the realistic budget for a full Atlantic circuit? A realistic all-in budget for a European sailor completing the full clockwise circuit over 18 months to two years, with a suitable bluewater boat already purchased, runs £50,000–£100,000. The 10% rule — budget 10% of the boat's value per year for maintenance and operating costs — is a reasonable starting point for boat-specific costs alone. The ARC entry fee for a 40-foot boat is approximately €3,000–4,000 and includes services in Las Palmas and St. Lucia.
What is the Azores' role in the northbound return passage? The Azores — specifically Horta on Faial — is the spiritual climax of the Atlantic circuit and the key staging port for the final leg home. From Bermuda to the Azores is approximately 1,800 nautical miles east-northeast, typically taking ten to fifteen days. From the Azores, the final 1,200 miles to the UK is usually a comfortable summer passage on westerlies or southwesterlies.
What rally options exist beyond the standard ARC? The ARC PLUS stops in Cape Verde before crossing to St. Lucia — an excellent addition for sailors wanting to extend the southbound leg. The RORC Transatlantic Race departs Lanzarote in January for Grenada, attracting competitive cruisers who want a January window. The World ARC is the circumnavigation rally on a two-year cycle, with entry fees of €15,000–25,000 for the full circuit through the South Pacific, Indian Ocean, and South Africa.
