When we approached the anchorage there was a fender used as a marker bouy and i could see a white spot. When we all went swimming later i had the mask with me to check the anchor and so i also swam to that white spot and it was a fresh sunken yacht. Maybe around 8-10m long, the name is "Duck" and the port of registration Freiburg. So it was a german sailboat. I could see the spinnaker pole and lifevests and other stuff, so it was not emptied by anyone. Of course i am now curious to know what happened. I will investigate :-) Check out the pictures.
