Onda Marina, Cesanatico lies on the Adriatic coast of Italy, 14 miles NW of the port of Rimini and 22 miles SSE of the harbour of Ravenna. The marina provides a total of 300 berths for yachts up to 23 on the Adriatic coast of Italy, 14 miles NW of the port of Rimini and 22 miles SSE of the harbour of Ravenna. The relatively restricted depths in the entrance mean that the harbour is only suitable for entry in settled weather and close to high tide.
