The four hour trip is perfect for when the pelagic are just outside of the reef, target species fishing like shark or tarpon, reef fishing for bottom species and snappers, or if you have time constraints. This one's great for the smaller kids.
Six hours is ideal for going off shore to troll for Mahi, Sailfish, Tuna; wahoo and more or the reefs and wrecks.
The eight hour trip gives you ample time to mix things up. Head out to the deep blue looking for those wall filling trophies, fish the wrecks and still get some fast paced action from Snapper or Mahi.
