For a ship with a length of less than 14 meters we always find a place, but you can make a reservation.
Is your ship longer than 14 meters? then it is wise to make a reservation, the number of berths for larger ships is limited.
If you come with a group of ships, it is certainly wise to make a reservation.
Reservations: Call the harbor master or use WhatsApp: 06 51 59 77 16.
