Since the mid-1990s, surfboard maker James Fulbright has been taking friends and acquaintances into the Gulf of Mexico to surf waves created by oil tankers. In 2010, persuaded that visitors would pay for the thrill, he turned the trips into a business. After the spill, three-quarters of his bookings canceled, despite what Fulbright, 53, describes as a "minuscule" amount of oil in the Galveston region. Board and equipment sales, which account for 60 percent of his revenue, remained steady throughout 2010. Now the surfers are coming back, Fulbright says, and he has booked about two charters a week from May through September.
