I'm fishing in a river system that as current, sometimes can go up to 5 miles per hours average is 1.5 ,to be able to stay in contact with bottom vertical jigging to the boat aint easy ,you gotta drift at the most one mile per hr.
Boat control is critical, you gotta figure wind direction ,current flow ,electric motor speed and weight to use to stay in the zone of targeted fish,once you figure it all out,that put fish in the boat see the result in pictures.
