But big blues are not limited to deep canyon waters, and will venture inshore to 20- and 30-fathom depths to seek their favorite forage. Last year, Capt. Nick Savene from Oceanside, New York, trolled up an estimated 550-pound blue marlin south of the wreck of the British tanker Coimbra. His angler fought and released the billfish in 180 feet of water south of Shinnecock, New York. Back in the late ’90s, Capt. Billy Martin and “Mako” Mike Townsend lost an even larger blue in only 17 fathoms, southeast of Fire Island, after a punishing nine-hour fight. The moral of these stories is that if you have 73-degree water off Long Island with an abundance of forage like dorado, skippies and other small baitfish in the area, a hungry marlin can make an appearance without warning. If you fish the Island’s fertile offshore waters and get the chance to tackle a big blue marlin, consider tagging and releasing it to fight another day.
