Pacific Passage Planning: Distances, Seasons and the Long Reaches

The Pacific asks more of a sailor than the Atlantic and gives more back. The distances double, the logistics thin out, and the rewards arrive as coral atolls, empty anchorages and passages measured in weeks of trade-wind sailing. The standard route west from Panama to the Marquesas covers roughly 3,800 nautical miles with no stop, the longest landless leg most cruisers will ever sail. Planning a Pacific season is an exercise in respecting two calendars at once: the cyclone seasons that divide the year, and the provisioning maths that divide the boat. Get those right and the Pacific delivers the sailing of a lifetime; get them wrong and the same ocean becomes a very long way from help.

The Two Seasons That Rule the Basin

The South Pacific cyclone season runs from November to April, and the North Pacific hurricane season fills roughly the same months. The working calendar for westbound cruisers follows directly: cross from Panama to French Polynesia between February and April, spend the safe season working west through the Society Islands, Cook Islands, Tonga and Fiji, then commit by November to a cyclone haven, either south to New Zealand or north to the equatorial islands where cyclones rarely tread. The Marquesas leg itself sits in the transition between the two hemispheres' trades, and the first half often serves up the light, squally doldrum conditions of the Intertropical Convergence Zone, usually crossed between three and eight degrees north.

The Long Reach: Panama to the Marquesas

Everything about the big leg is a resource problem. Three thousand eight hundred miles at an honest 130 miles a day means 29 days at sea, and prudent crews provision for 40. Water planning dominates: a crew of two needs 240 litres carried plus a working watermaker or jerrycan reserve. Fuel for the doldrums matters more than on the Atlantic; motoring through three days of glassy calm can burn a quarter of the tankage. The sailing itself is gentler than its reputation once the trades establish: long reaches in 12 to 18 knots, a swell from astern, and the deep routine of a watch system running for a month. Chafe, sail wear and the slow failure of anything not maintained become the real adversaries on a leg this long.

• Provision for 40 days on a leg most boats sail in under 30.
• Top every tank in Panama; the next reliable diesel is in the Marquesas.
• Carry charts and guides for the Gambiers as a bail-out; they sit 300 miles south of the direct line.
• File a float plan and hold a daily check-in; the Pacific is big and traffic is thin.

Choosing the Stops West

French Polynesia grants limited visas and finite time, so route planning is really time budgeting. The Marquesas deserve two weeks; the Tuamotus, with their pass entries timed to slack water, reward slow exploration; the Society Islands close the permit for most boats. From there the choices multiply: the Cook Islands, then either Samoa and the northern route, or Tonga and Fiji on the southern line, converging on the November decision. New Zealand demands a seaworthy boat and honest answers at biosecurity inspection but offers the safest cyclone season in the hemisphere. Each hop west is short by Pacific standards, three to ten days, and the passages between them, with reefs and passes and the occasional late-season trough, demand sharper navigation than the open-ocean legs.

The Pacific Rewards the Patient

What separates a good Pacific season from a grinding one is rarely seamanship; it is pacing. Crews who budget rest weeks after the long legs, who wait for weather windows on the short hops instead of sailing to a calendar, and who treat the November deadline as immovable arrive in their cyclone haven with stories instead of repairs. The ocean is the same water Magellan named for its calm. It simply insists that those who cross it come prepared for its scale.
