• Free on Wednesdays, when the boat and wind energy exhibitions open from 1pm
• Allow about two hours, the museum's own estimate, spread over three floors with an elevator
• Signs in Polish and English throughout, so kids can follow along without Polish

A branch of the National Maritime Museum in a brick-and-glass building on the Motława. Its interactive hall, "People, Ships, Ports", has over 60 stations: ship and bathyscaphe simulators, a lifeboat and evacuation chute, and a pool with a wind generator where kids sail remote-controlled model ships.

Over 40 traditional boats fill the glass lobby and the "Boats of Peoples of the World" exhibition, from a Venetian gondola to a sampan.
