It strings together the Atlantic Intracoastal Waterway, Chesapeake Bay, the Hudson River and New York canals, Ontario's Trent-Severn Waterway, Georgian Bay and the Great Lakes, the Illinois and Mississippi/Ohio rivers, the Tennessee-Tombigbee Waterway, and the Gulf Coast back to Florida.\n\nMost boaters ('Loopers') go counter-clockwise from Chicago or Florida and take about a year, following the seasons: Gulf and Florida in winter, the ICW and Chesapeake in spring, Canada and the Great Lakes in summer, and the rivers in autumn. The route has no official start, and boats range from trawlers to sailboats that un-step the mast. Completers switch from a white to a gold burgee, and AGLCA supports the community.\n\nThe Loop is hard in a practical way rather than a wild one. You need about 19 ft 1 in of air draft for the fixed bridge near Chicago, you share rivers with commercial tows, and you have to plan around the Gulf crossing, Great Lakes weather, lock closures and high-water events.",

No tolls are charged.\n\nThe authorized depth is 12 ft from Norfolk to Fort Pierce and 10 ft from there to Miami, but funding limits mean shoaling is common.

Seattle to Ketchikan is about 650-660 nautical miles, including roughly 520 miles in BC.\n\nCruisers usually go from May to September, taking about a month round trip or several months to explore properly. Most boats plan around tides, using slack water at Dodd Narrows, Active Pass and Seymour Narrows. Anchorages are frequent and often deep, and cruisers clear Canadian and US customs at the border.\n\nWildlife and scenery draw boaters to orca, humpback whales, bears and glaciers. The challenges are strong semi-diurnal tides, currents up to about 16 knots at Seymour Narrows, unpredictable weather, fog, deadheads and deep anchorages. The open stretch around Cape Caution adds swell and exposure.",

It is the classic way to go from the US east coast to the Eastern Caribbean, and Bruce Van Sant's book The Gentleman's Guide to Passages South (10th edition, 2012) made it famous.\n\nThe idea is to head east-southeast against the 15-25 knot trade winds, using short hops, night departures and the calmer water under land. Van Sant relies on land-cooled winds and lee effects, and cruisers usually time passages for light winds between fronts. The route is usually done from November to May, outside hurricane season, and takes several weeks to months.\n\nIt stays close to harbors, but it is not easy. The route is about 1,200 miles, mostly upwind, with shoals in the Bahamas and Turks and Caicos, and strong, unpredictable currents in the Mona Passage.",

Around 150 boats leave Las Palmas de Gran Canaria each November for Rodney Bay, Saint Lucia. The fleet ranges from 27 to over 100 feet and includes monohulls, catamarans and motor boats. The ARC course record (2016) is 8 days 6 hours, set by the maxi Rambler 88.\n\nMost cruisers leave in November, after hurricane season ends and as the NE trades fill in. They sail south-west to pick up the trades, then run west on a long downwind leg. A typical cruising yacht takes roughly 18-21 days. Many boats stop at Mindelo in Cape Verde first, or start there to shorten the crossing.\n\nIt is the most popular ocean crossing for first-time bluewater sailors, and it is mostly steady, warm, downwind sailing. The challenges are sustained rolling in the swell, gear wear from weeks of downwind sailing, squalls, and the isolation of a fleet that spreads out over 2,700 nm.",

They pick their way out of Mexico in light airs, cross the equatorial convergence zone with its squalls and calms, then finish with about two weeks of SE trade winds of 15-25 knots.\n\nThis is one of the longest non-stop passages most cruisers make.

Many head south from Tonga or Fiji to New Zealand for refit and rest, then return the next year.\n\nPassages between islands are short, from a few days to two weeks, but the route is not easy.

Roald Amundsen made the first complete ship transit in Gjoa between 1903 and 1906, taking three years.\n\nThe passage is only navigable for about four to six weeks from roughly the second week of August, in a good year. Yachts generally arrive in the second half of July, wait at Nuuk or in Baffin Bay for the ice to clear, then go west. Sea ice usually retreats west to east, so the eastern end clears last.\n\nDistance is about 2,300 nm depending on route. The real challenge is ice, poor charting (only a small part of the Arctic is charted to modern standards), fog, and dozens of permits and permissions. An ice pilot is widely recommended. Only a handful of yachts make it through each year.",

About 430 nm (800 km) wide from Cape Horn to the South Shetlands, it is the shortest crossing from Antarctica to another landmass. The Antarctic Circumpolar Current flows through it with no land in the way, which produces some of the most feared seas in the world. Waves over 12 m (40 ft) are reported.\n\nYachts typically leave from Ushuaia or Puerto Williams, in Chile, after clearing out and waiting for a weather window. The usual heading is about 140-150 degrees true, often towards Cape Shirreff on the northern South Shetlands; from Ushuaia or Puerto Williams to the Antarctic Peninsula is about 600-650 nm. Expedition ships take about two days each way; small yachts commonly take longer. The season is roughly November to March.\n\nThe passage itself is the challenge: fast-moving low-pressure systems, big seas and cold. Every Antarctic yacht expedition must be authorised by the skipper's flag state. Advance notification should start at least six months ahead, and a post-visit report is required.",

The speed limit is about 15 km/h (8 kn), engine under power, with sails normally only as an aid. Until the end of 2026 a fee applies, reported at roughly 12-43 euros by length, and from 1 January 2027 passage for pleasure craft is reported free.\n\nTypical passage takes most of a day, often with a night at a canal mooring, sharing the water with big ships under bridges of 42 m clearance.",
