Was out of manasquan inlet today about a half mile off of bay head fluking. Drift was very slow so we tried slow trolling. After about ten minutes, i saw a nice mark on the fishfinder on the bottom. Didn't think much of it, then one of the rods went over. I grabbed the rod and something started peeling off line. After a few seconds the line snapped off. About 5 seconds later a 5 foot thresher came shooting out of the water about 50 feet behind the boat. The fish jumped straight up into the air and its whole body was out of the water. It jumped a second time the same way. It was an amazing sight which made up for the awful fluke fishing.
