What do boats like the Pollux, a magnificent steel three-masted schooner, the Amstel Botel, a former riverboat cruise ship that was transformed into a 3-star hotel, and the Sirius, a famous Greenpeace ship, have in common? Nothing, despite the fact that they're all moored adjacent to the NDSM shipyard in the Maritime Quarter, a striking collection of ships and buildings situated around a long jetty. Other impressive vessels include the red Irish lightship Finley that attracts cultural party-goers from around the city, the old Russian submarine and the wooden Mahu M880 minesweeper. Right next to the ferry is the platform for De Pannenkoekenboot (Pancake Boat) where hungry diners can enjoy a cruise and an all-you-can-eat pancake experience.
