Kite surfers are not a threat to the public, say supporters of the sport

Sandra and Garry Taylor, who live nearby, said the situation at Llanddwyn near Newborough was getting worse with kite surfers "tearing" around.

But the chairman of the British Kite Surfing Association said standards of both training and safety were extremely high.

A spokesman for Anglesey Council said a complaint was being investigated.

"This is a blue flag beach and these kite surfers tear up and down the place," said Mrs Taylor.

"They could hit a kiddie in the water. They are really prolific here on any windy or sunny weekend," she added.

The beach is looked after by a management team, of which Anglesey Council is part. A council spokesman said it had received a complaint and was looking into it.

Richard Gowers, chairman of the British Kite Surfing Association, said teaching standards and safety were both very good in north Wales.

Kite surfers usually looked for safe beaches to use, and often went for quieter ones as a consideration to other beach users, he said.

"It is very seldom to have a conflict of interest with other users and if there is it's usually sorted out by a meeting between the two parties," he said.

"In the seven years the sport has been around there has only ever been one accident involved the public that I know of.
