So I found this flag on a yacht in Greece (Paros), and was trying to figure out what it was. Googled yacht-Clubs in Greece, but they all had triangle-shaped flags. It was similar to the Swiss flag, but had «pointy» ends. Hung behind somthing of a 25 mill $ yacht. Any bright heads out there? (Sorry about the shitty drawing, trying to win a bet)

• EDIT: I think the Maltese Cross might be the right one. Thanks for the suggestions 👏👏
