My old roommate and his buddys land smaller ones from the surf at night. Ocean County, but I'm sure Monmouth is no different. They made a video
I've only encountered one large shark in NJ while surfing. About 8 foot. My buddy was taping us surfing so we have it on video somewhere. It was followinng baitfish, and seemed to care less about us surfing.
I spent a week in FL suring, and saw 3 while surfing.
