The device consists of 84 inches of buoyant, fluorescent-green fly line tipped with a blaze-orange cork at one end and a four-foot fiberglass handle at the other. "Through 15 years of promoting tournaments, we've found that a 165-pound striped marlin is, on average, going to be very close to 84 inches long," explained Harvey Hunnicutt, president of International Gamefish Tournaments. "A striped marlin is brought alongside the boat and billed. The boat is then kept moving very slowly. The measuring stick is used by placing the front of the fly line at the tip of the fish's lower jaw and allowing the floating line to trail back to the fork of the marlin's tail," said Hunnicutt. "If that distance along the marlin's body is shorter than the fly line, chances are great the marlin will not qualify for weigh-in and should be released. If the fish is longer than the measuring line, obviously, it should qualify to be taken."
