How are you going to hunt the gator? If you are using a catch line and baited hook, then you can just use your normal setup to dispatch the gator once he is caught.
If all bow, then I would recommend shooting him with a bowfishing setup first. The line on the bowfishing arrow should be attached to a float. You probably won’t need the float, but you don’t want the line attached to your reel, just in case!!!! After you get a couple bowfishing arrows in him, then you can maneuver him into position for a kill shot. Again, you can use your normal arrow/Broadhead combination for that. This is the method I used to take my 11’1”, 390# gator here in Tx. The bow I used was a 52# Bob Lee recurve.
Gators make some of the coolest looking euro mounts there are!
