I am a part time resident of islamorada. I dont have my numbers book with me but you can ask any tackle store employee for the numbers. Ask for the islamorada hump which is about 15 miles offshore and the 409 hump which is about 23 miles from islamorada. Both humps will hold plenty of football sized blackfin tuna. I like to troll small feathers for them. Dolphin have already showed down there in numbers so they shouldnt be too hard to find. Just point your boat offfshore and look for the flock of feeding birds and you will find dolphin. Be sure to bring plenty of fresh hoos.
