I prefer to use hand lines for trolling while sailing. On occasion though a stout pole is handy when you are in mahi or wahoo country
I have sailed and fished all along the west coast of Florida and have always had good luck with the setup described in a thread I created on one of the other sailing forums. Pretty easy to make and not expensive.
A Simple Handline for Trolling while Sailing
A bunch of the guys with kids around the marina made pairs of them up and the kids have been having a ball catching fish.
Hope you give it a try and good luck with your fishing.
