As such they are unpredictable. They are eating machines, hungry enough, confused by surf, lack of water
clarity etc they can do a lot of damage even if they spit your dog out regardless if "they are not on the shark diet list". Incidentally, Mules kill more people every year than sharks! Maybe some sharks are onry not hungry!
, I would avoid later afternoons (maybe 3pm on?) as that is when I see most sharks foraging , including right under your boat in 13 ft of water!
