It is the meeting point for families, for bathing beauties, daughters and mums, who lie on their paddle boards floating in its vicinity and for the various kids clubs who have kayaked out. The pontoon is surrounded by splashes and laughter.
But to those who know, just beyond but in its shadow, is another world, a submarine world of crystal clear turquoise waters, small shoals of shimmering small fish, greater launce and garfish. Black spiny sea urchins lumber across the rippling sands below and flatfish wriggle their way into the sandy patches between beds of eelgrass.
To enter this world requires snorkel and mask, a watchful eye for dinghies, ribs, SUP's and falling bodies. But it is there, hidden away, another submarine world!
