If you are paddling and are not under power of any motor you can not get one. If you are under power (including trolling motor) and are impaired and you get stopped you will get a DUI. No such thing as a BUI. If you are stopped while driving a motorized vehicle impaired, don't matter if it's a car, boat, golf cart or cuttin grass in your yard on the lawn tractor you can get a DUI. They will take your drivers license same as if you were stopped on the highway.
