So there we were, on our noisy tourist boat moored next to a beach on Paxos, as hoards of said tourists dived in and swam towards the beach.
Along side us was a massive private motor yacht. As we watched, the back of the yacht opened up to reveal a bay housing a smaller powerboat and to then form a platform for swimming from. Crew members hosed down the platform and carefully placed a director's chair on it.
Moments later we noticed an elderly man sitting in the chair as the crew put flippers on his feet and a snorkel and mask on his head. He then descended the steps into the sea followed by one of the crew who also got in the water. The old man then swam (well I say swam but it was more like controlled drowning) towards the beach. The crew member swam alongside him - towing a life belt - just in case.
We were left feeling more stunned than jealous.
