Not waypoints but link to Thorness Bay.
My favourite place to go.
It has a large reef jutting out that catches the unwary. Many props worse for wear after crossing it. You can just make out the dark shadow in the water.
You can reach the beach on the other side (Holiday camp side) of this reef at mid to high tide, but if you stay beyond that, the reef is waiting for you and the land dries out completely. However on the 'Cowes' side of the reef you can come in at low tide carefully and step onto the reef. all smooth clay/sand with no obstructions below. Leave at anchor and wade in.
Best advice, as always, to watch a complete cycle of the tides to see what happens under the water, but always fun having the knowledge to then be more confident running up to the shore at any time.
