I've got a 24 volt system and a light boat, I don't experience any jerkiness. In higher winds you do get some drift, but the unit provides a smooth increase in power until it gets back where it needs to be. I've watched it as I've drifted back...it will start on power level "1" and then increase it as necessary to get back to the spot. This is FAR superior to my old method where i had to fight it the whole time. I can tell when I'm drifting off my spot and I simply adjust my casts as necessary.

All systems have weaknesses...but this thing works like a champ for me. It is far and away better than anything else I've used. I don't ever want to own a unit that doesn't have these features.
