“I fish isolated areas that I call cities,” says Helmey, who first fished many of the areas with her father, Moose, who was a charter captain. As she got into the business, she discovered additional cities, which describe areas of natural bottom rising 5 to 6 feet above the surrounding sand. These cities almost always hold big red snapper — her biggest of 2018 was 32 pounds — along with cubera snapper, groupers, amberjack, and cobia. “Cities have the highest population of fish” compared with lower-profile areas on the snapper banks. Helmey has about 40 years’ worth of detailed fishing records, which helps her decide which cities to visit.
