Most waters, but not all in the southern part of the state allow trolling. Row trolling has been an art form for muskie and walleye for years here in the Vilas/Oneida counties and is legal on all WI waters far as I know. They actually make a row trolling boat (Looks like a flat stern canoe)!!! Only on the flowages is motor trolling allowed here in Vilas/Oneida. My heaviest muskie (44″, 28#) came while row trolling planer boards and four lines (another fishing with me). One of the intriguing things about fishing the NW WI lakes is the opportunity to motor troll. While there has been great arguement about the 50″ muskie size limit up here on several lakes and it was voted down by the local counties, I would really only go to those lakes in the NW part of the state to be able to troll. I feel comfortable that a 50″ fish resides here in many of waters that I fish.
As for casting frequency, just keep casting or slow the boat down or drift. Many muskie fisherman feel that by casting a plug during the fall season, it allows them to trail a sucker behind the boat. If drifting, in my mind, this is an allowable situation. If the bowmount is in, you’re casting and trailing a sucker, be careful!!! If you’re vertical jig fishing, use the trolling motor to slow yourself down on your drift. Going into the wind while vertical jigging could get you in trouble.
If you slow your boat to a crawl, you could be trolling if you continue to move your boat in a direction that keeps the line at an angle rather than vertical. Hopefully they would view your move of the boat back toward your line an effort to keep your line vertical and thus legal.
Good luck and keep a VERTICAL line!!!
