From the bridge of the three-masted windjammer, the Sea Cloud Spirit, the captain called out the words we’d all been waiting for.

“Let’s set the sails!” he cried, after turning off the engines, while maneuvering to maintain an optimum angle for his 18 deckhands to climb into the shrouds and unfurl the ship’s 44,132 square feet of sails by hand.

Like acrobats, the crew scurried up the masts to the upper topgallant sails that rose nearly 200 feet above us. The ship’s captain, Vukota Stojanovic, later insisted that none of it was for show. “Whenever there is an opportunity to sail, we sail,” he said.

For the next hour, the crew hauled the ropes until the 28 sails were billowing in the wind, propelling the 452-foot-long ship — the world’s largest passenger sailing vessel on which the sails are raised by hand — toward its first port of call, Portofino, Italy.

At a time when cruise lines are packing their ever-more-gargantuan ships with water parks and basketball courts, the 136-passenger Sea Cloud Spirit, with its old-fashioned clipper design and wooden decks, stands out. It is the newest ship from the Hamburg-based Sea Cloud Cruises, and while it is the company’s biggest, Sea Cloud said it wanted to leave space for passengers to connect to the surrounding elements.
