For race car nuts, it's the 24 hours at Le Mans. For big-game fishermen, it's the five tournaments that make up the annual Bahamas Billfish Tournament. Ever since 1973 when Bimini, Cat Cay, Chub Cay and Walker's Cay created the first Bahamas Billfish Championship, the best sportfishermen have been coming to the Bahamas each spring with the latest in depth sounders, radars, underwater cameras, infrared, high-speed engines, and all the design tricks money can buy. No wonder last year's championship saw record numbers of fish hooked: In the five events 383 billfish were caught compared with 301 in 2004 (only nine of them were weighed in; the rest were released). You might think the fish have gotten stupider. Not true: boatbuilders and their fishing clients have just gotten smarter.
