Chris Dixon, author of Ghost Wave: The Discovery of Cortes Bank and the Biggest Wave on Earth, will be at the Windjammer on Sat. Aug. 25 promoting his book. Take a break from the beach at 4 p.m., when he’ll be giving a photo and film presentation on the massive waves of the Cortes Bank and the big wave surfers, like Greg Long and Mike Parsons, who’ve ridden the waves.

“The presentation will hold much of the same footage as the Surfrider Foundation party here in Charleston last winter at the Hippodrome, but with a few scary new additions,” Dixon said in a recent email. “Tropical Storm Emily swell will likely be in the water, so once you see some virtual waves on the Windjammer screen, you’ll be able to paddle out and catch some real ones — though they’ll probably not be quite as big as Cortes.”
