Le Boréal and Le Soléal, two ships of the French expedition cruise shipping company Ponant, have North West Passage from Greenland in the east to Siberia in the west.

"Having achieved a first for France in 2013, Ponant has pulled off a world first with two of its ships crossing the passage three days apart on the historic explorers’ route via the Bellot Strait. This latest achievement is the culmination of more than 15 years’ experience sailing in the Arctic and Antarctic regions," the company said in a statement.

“It is with great pride that we announce this crossing under the French flag, unique in international maritime history,” said Jean-Emmanuel Sauvée, Chief Executive Officer of the company.

Captains Etienne Garcia and Patrick Marchesseau on Le Boréal and Le Soléal ensured their passengers were able to take full advantage of an extraordinary experience aboard these two luxury yachts. Designed to sail in extreme regions, each has 132 staterooms and suites and have obtained the international Cleanship label from Bureau Veritas, the French classification society, for their innovative green equipment.

Along the voyage through the narrow channels and shifting glaciers of this little known region, they explored historic landmarks like Beechey Island of Franklin expedition fame, Gjoa Haven where Amundsen anchored his ship over a century ago, and Cape Bathurst. They also saw hundreds of belugas, around 60 bears and nearly 500 narwhals. Another highlight for passengers was meeting French adventurer Charles Hedrich, the first man to cross the Northwest Passage solo in a rowing boat.
