Noel, should’ve said something when we were out last weekend. I’m sure some of those saugers would’ve given us a chance to practice up.
The hard part is letting them run with the bait and holding off on the desire to rap the bail closed and lay into ’em. The real trick is picking up the slack and knowing when to throw in the hookset. Basically just like B said, and when you feel the tick, drop the line. Pull line from the reel and feed it out with your left hand for a few seconds, then close the bail. Now comes the hard part. Start reeling very slowly and when the line tightens up, if you feel any weight or bounce, stick ’em with the hookset.
As far as boat control (your original question), I usually do it in relatively still water where there’s enough wind to push the boat. Heavy current causes a lot of problems with the rig itself, since the boat is drifting downstream, dragging the weight downstream with the current taking the bait in front of it downstream (see a trend here?) I usually end up with a tangled nightmare if the current is too swift, but if you can slip the current with the electric motor and keep the entire rig downstream, it can still be effective. One thing to remember is that the rig is designed for lakes, where the fish is essentially running away from you.
