The event is set for Sept. 27-29.
Beach tennis is one of the quirkiest and fastest growing sports in the United States and has deep roots in Hermosa, according to organizers and U.S. No. 2 ranked player Mark Bonfigli.
Hermosa Beach in 2010 was certified as having the first internationally recognized beach tennis courts in the country, organizers said.
His company, Dealer.com, is sponsoring the event.
Beach tennis, said Bonfigli, began 40 years ago, in Ravenna, Italy, near the sea.
Since, then, it has taken off all over the world; it is highly addictive, proponents of the sport claim.
The learning curve for the game, said Bonfigli, is easy.
Anyone can walk onto the court off the street and begin enjoying a volley within 15 minutes, he said.
The game is scored pretty much like tennis, though there is no advantage point for a "deuce" 40-40 and there is only one "out" allowed per serve.
You can serve from anywhere behind the boxes and the ball is larger than adult tennis; it is the size of a ball used for children 10 years old and under.
The racquets are also not strung. they are solid, with holes in them, looking more like paddles.
The court is laid out like tennis, however, but the game is always played in doubles, as in volleyball.
According to Bonfigli, enthusiasts -- it is run by the International Tennis Federation -- hope to get it placed on the list of Olympic events.
It is a pro sport but there will also be amateur competitions and prize money will be awarded.
