Meaning
A large passenger ship or cruise liner with several decks and a tall funnel. It stands for cruises, ocean voyages and holidays at sea.
Use it for cruise holidays, ports of call and long voyages: “Seven nights on the 🛳️, first stop tomorrow morning”. Travel agents use it for cruise offers. For a short crossing, ⛴️ fits better, and 🚢 is the general-purpose ship.
