Sandy Cove flyover. Posted on February 12, 2021 at 5:23 pm. This is an artist’s impression of Sandy Cove to give a vision of Newlyn Harbour. The curved breakwater will reduce the impact of storm waves and tidal surges at the same time provide deepwater berths that will cater for much larger fish, sail and commercial vessels who ply their trade on the sea around Cornwall. Please not, as this is an artist’s impression the scale and dimensions are an indication of how the planned development may appear.
