Stock Photo - 05 January 2022, Mecklenburg-Western Pomerania, Greifswald: A man takes down the fairy lights on a traditional sailing vessel in the museum harbor. About 60 historic sailing ships, fishing trawlers and pilot vessels are winterized in the museum harbor. Due to the Corona protection measures, hardly any guest cruises were possible on the aged ships in the last two years, and the new adaptation of the ships to the new Ship Safety Ordinance poses major problems for many operators. Some traditional ships have already had to be scrapped in recent years. Photo: Jens Büttner/dpa-Zentralbild/ZB. - Greifswald/Mecklenburg-Western Pomerania/Germany
