The BC Buoy is a well-known mark on the east-of-Chatham grounds, sitting in deeper water near the shipping lanes about ten miles east of Crab Ledge. Anglers often scan the area around it for marked bluefin as they work between the inshore ledges and the outer wrecks.
The ground
The deeper water and the lane structure hold bait and fish. Because it is deeper, the tuna often hold down, so your sounder does the finding.
How to fish it
Give the area a good scan for marks, then jig fish you find and troll to cover water. Mind the commercial traffic in the lanes.
Mind the traffic The BC Buoy sits in and around the shipping lanes. Watch AIS and the radio, stay out of the traffic separation lanes, and keep clear of large vessels that cannot maneuver around you.
About the coordinates The coordinates on this page are an approximate reference to orient you, not a navigation waypoint. Fish move, and numbers vary boat to boat, get exact, current marks locally and always run on a plotter with proper charts.
Regulations Tuna are federally managed highly migratory species requiring an HMS permit, with category, size and retention rules that change through the season. Confirm current rules with NOAA Fisheries HMS before fishing.
