All over Europe, people are waiting and hoping to find out whether foreign summer holidays will be possible. Many countries are currently banning or strongly discouraging them, and returning travellers have to quarantine on arrival. Greece is among those that are heavily reliant on tourism and looking to open up for foreign visitors who have been vaccinated or who have had a recent negative Covid test. With coronavirus cases still surging in many parts of Europe, the situation is uncertain. April is normally the start of the tourist season for boat owners at the dock of this harbour in Athens, but things are on hold because of the pandemic. Eugene Theodoridis and his team rent out catamarans and yachts for trips to the Greek islands. Their clients come from the UK, the United States, Germany and South Africa. "All through the winter, we have been preparing the boats in order for the tourists to come," Eugene told me. "We will be ready when the borders open and we can welcome all guests throughout the world."
