I use a stiff rod 1-6oz and conventional reel (penn 535 6:1) and power pro 50lbs. I slide a 1/4 oz egg weight on main line and then tie main line to the large Sampo ball bearing swivel. I use 50lb-80lb mono leader around 4 to 5 feet. I use 8/0 cirlce hooks or 8/0 regular gamagatsu hooks on the end of leader. I prefer big eels 12"-18". A 20lber will gobble this up no problem. Push the hook under the chin or mouth and out thru the left or right eye. I use improved clinch knots on everything but that is the anglers choice.
I let out as much line as possible but usually ends up 30-40 yards behind yak. Your trolling speed should be a crawl or if possible a drift. Just enough to take up slack and allow the kayak to have movement. I troll with rod holder up front to watch the action. I troll in areas loaded with structure, especially lobster, crab beds, boulders, mussels beds etc. The fish finder realy helps with this. I leave my drag tight but not tight enough to have a break off. When you are trolling, and watching your rod up front you will see it bounce up and down and then stop, continue your speed and put on your seat belt. That bass will come back and take it so hard it will be incredible. If you grab your rod and lay a set and keep your rod high you will be on. Some oldtimers say when they troll eels and see the rod dancing up and down the bass just whacked it with it's tail and then comes back for it. Who knows. All I know is this method works. I have trolled eels thoughout this season and have nailed many big bass. Next to the tube and worm for the daytime this is another way of catching jumbo bass at night.
I hope you nail a 50lber plus....I know we have that chance while trolling eels at night. For a $1 or $1.50 from most bait shops this is well worth it. This is a great way to get away from smaller bass and get into the lunkers. Bluefish are our enemy when trolling eels. When the big bass are present be prepared to have a dozen eels ready.
Having a soft cooler, ice pack, and damp rag the eels will last. Most important for me is having a green scrubby that are used for dishwashing to handle eels. Here are a couple of pics of the power of a trolled eel:
