One time on an 80lb bat ray hook-up using 10lb test, it hauled me from Belmont Pier to 55th Street on the peninsula, about one mile. In late summer and fall they are spawning actively, and easy to hook-up but sometimes difficult to land. Rat tails or bat sting rays can weigh over 100 lbs and measure 6 feet wide from wing tip to wing tip. There's no common average size. One hook-up may produce a 2 pounder, while the next can be a 100 pounder.
Shovelnose sharks are the most abundant biters.
They can reach 30 lbs but they usually average 2 to 15 lbs. The leopard shark is also a fighter like his cousins the gray and oilier or brown shark but gets much bigger. He can reach 45 to 50 lbs and 6 feet in length. Smoothhounds resemble closely the pelagic deep ocean sharks but lack the large teeth of their relatives. Late summer and fall is the best time to fish for these bottom dwellers.
