The museum is very large, and it will take two days to look at it roughly. If you look at each presentation board, it will take longer (at least half of the exhibition boards are only in German). I mainly looked at the navigational part, from the earliest sailing boats to the later steamships, the latest yachts are all-inclusive. And the exhibits are very deep, such as 1:1 cabin rooms, various knots, lifting ratchet mechanism objects, various engines, propellers and related technology interactive models, diving equipment of all ages (some very close to bluefin tuna) and so on.
