Ananova:

A couple who use a speedboat as a floating brothel to lure customers from a nudist beach are being hunted by police.

Shocked bathers looked on as a stream of men swam out for one-hour frolics in the cabin.

On one occasion the Bayliner sped off before police could give chase.

The power boat has been a regular visitor to Studland beach this summer.

It weighs anchor then a man swims ashore, alerting punters to the woman on board.

Emma Wright of landowner the National Trust, said: "You know something is going on.

"Men swim out to it one at a time and emerge again after an hour or so."

Swanage police are upping patrols at the beach near Poole, Dorset, which attracts thousands of naturists.
