I fish near Sarasota not Naples but i know theres really good shark fishing there i would try any of the artificial reefs or wrecks offshore or around the passes on a outgoing tide at night,Try to Catch bonita, Barracuda or anything oily and bloody and set a chum slick im shure u wont have a problem hooking up with big shark over there, as far as makos there not as common here but there around i would fish the deep water wrecks and springs 40 miles plus. in Feb- March when the waters cooler Theres been more makos each year by me in sarasota i know they caught some nice ones in the last two years
