Line counters just make things easy. Take the reel, pull line off the reel until the line guide goes all the way across the reel. Measure the line that came off the reel in that "pass". Let out the proper amount of passes to achieve the distance you want your lure out. For Divers, you want a Medium heavy rod. If they are medium or medium light, they are a little on the light side unless you are using smaller divers. I used to fish the lake as a teen out of a 14' smokercraft. You had to really pick and choose your days. You can do it. There is not reason wny you can't add riggers to the boat. I had small cannons on my old 14' boat. They worked great.
