#1: This is your basic rigging when fishing from a boat and can be used with everything! In place of the hook you can attach an artificial lure, steel leader or any rig like the #5 diagram below.
#2: You can use removable weights to adjust quickly to drift deeper, fish the bottom or just cast further.
#3: You can use a heavier slip sinker for a Jig & Eel effect but also let the bait run up a little. The bead will stop the live bait from running too far so that you can't feel a strike or snag in the structure. This is a good rig for drifting for grouper.
#4: This is a good trouble free rig for both at anchored and drifting when you know how much weight you will need.
#5: The swivel serves two good prepossess! First, when going from light leader to a much heavier leader, it will work better then a Blood knot. Second, it will work as a stop for any big fish trying to pull you into the structure that could cut your lighter leader or line. This is often the case when fishing grouper in heavy structure. I may make this rig with as much as 200# test mono but that is the extreme. Normally 100# to 150# mono will do the job.
