The history of Sassnitz is shown, such as the development of the island's first seaside resort, seaside shipping, port development, the start of regular postal steamer services and the opening of ferry services to Scandinavia, the history of fishing and fish processing, the naval location and the sea rescue service. Special pride is the walk-in museum ship "HAVEL", a 26.5-meter steel cutter, which is the only one preserved true to the original of once 50 vessels used in Sassnitz fishing.
The development of regional fishing in Sassnitz over the last 150 years, the ferry connections to Sweden and Lithuania, and the ports of Sassnitz and Mukran are the focal points of the Sassnitz Fisheries and Port Museum in the island town. These are vividly documented with the help of port models, among other things. The highlight of the exhibits, however, is the walk-on museum ship Havel in front of the museum, a steel cutter that measures 26.5 meters and is the only one of the 50 cutters once used in Sassnitz fishing to have been preserved. Once a month, following an old fishing tradition, so-called storm talks are held. They go back to the meetings of the fishermen, when the storm at sea prevented them from sailing and instead they spun sailor's yarn together. At today's storm talks, which incidentally also take place in good weather, interested people are informed about topics such as fishing and town history.
