Hammerheads

Its been a weird year for sharks here in beaufort NC. Usually everyone sees lots of sand tigers around the wrecks and there is usually a big one or two hanging around the fish cleaning station in Morehead city when the sport fishies clean their catch etc but this year we have seen some big hammerheads as the divers call REAL SHARKS....Earlier this season I saw one that looked as big as my little 17 Mako in shallow water eating stingrays, I saw one coming in the inlet about 14 or 15 feet tearing up and eating a 7 or 8 foot sand tiger on the surface and last week I had one right next to my boat eat about a 20 lb king just as I gaffed it and all I got was the head..A dive captain frriend of mine had two of them circle him tuesday when he brought up a big grouper and he thought the bigger one was at least 10 feet long at AR 320 which never holds Hammerneads...I dont know that much about sharks but was wondering if Hammerheads are considered man eaters? IF they are I am going to stop drinking everything except Jack Daniels...Frank
