Greece has gone ahead and tightened measures on board Greek ferries after a sudden spike in Covid-19 cases, the government announced this week.

Starting on Tuesday, passengers will be required by law to wear masks inside and outdoors on ferry boats to the islands through to August 18.

Over the weekend, the government increased the maximum passenger capacity for ferries to 80 percent from 60 percent in view of the August peak holiday season to apply through to August 31. Ships with cabins have been given an 85 percent passenger limit – from the initial 65 percent.
