EWA BEACH, Hawaii: Brian Keaulana is the quintessential Native Hawaiian waterman, well-known in Hawaii and beyond for his deep understanding of the ocean, gifted with surfing and lifeguarding skills passed down from his big-wave rider father.

Now, as one of the islands' standard-bearers of surfing, Keaulana wants to further boost the sport in his homeland by building an artificial wave pool just down the road from the beach — a spot where competitive surfers could always be guaranteed the perfect breaks that are sometimes elusive in nature.
