Fonda Huizenga seems as down to earth as a mom in your local PTA. When you come right down to it, her biggest quirk is her fanaticism for blue marlin. Huizenga owns two women's world records for blue marlin fishing. Out of nowhere, she has become a top competitor in big-game sport fishing, and she is determined to collect more world records before she's done.

"Blue marlin for me is the epitome of a game fish. A blue marlin is like being hooked up to a thoroughbred race horse," she says.

World-record fishing for blue marlin is a rarefied sport because it's dangerous and requires enormous focus, patience and stamina--and because it costs thousands to participate.
