Navigation and the simulator on Deck 1
Deck 1 puts you in the headspace of a captain before GPS: compass, astrolabe, sextant, flags, pilot boats, and lighthouses explain how ships found their way. The simulator adds the physical thrill, with container-ship scenarios that make Hamburg's harbor feel less like scenery and more like a job.
Sails, shipyards, and life on board
The middle decks move from sailing ships and windjammers into shipbuilding, engines, work routines, and naval history. This is where Kaispeicher B feels especially right: a former warehouse explaining the labor, trade, and discipline behind the romance of the sea.
Sea research, art, and the treasure chamber
Deck 7 turns toward ocean science, while Deck 8 shifts into beauty and rarity: marine paintings, precious ship models, and bone ships that reward slower looking. It is a good stretch for couples and solo travelers because the rooms become quieter and more atmospheric.
Miniature ships on Deck 9
Deck 9 is the museum's tiny finale with enormous patience behind it: thousands of miniature ships make maritime history visible at a glance. If you enjoy details, slow down here; the smallest model is only about 5 mm (0.2 in) long, so the best discoveries happen close to the glass.
