A pile guide has a collar with a void therein. A planar flange extends from a side of the collar. A bracket has opposing guides constructed and arranged for receiving the planar flange of the pile guide therein. The planar flange is in a slidable relationship with the bracket, and the bracket is constructed and arranged for mounting to a floating dock. The distance of the collar from the floating dock can be adjusted to accommodate for distances of piles from the floating dock.
