A docking guide for a boat includes a platform having front and back sides, a first lateral side for mounting to a dock, and a second lateral side opposite the first lateral side. The platform has an opening, located between the first and second lateral sides, for receiving a front of the boat therein. The docking guide further includes at least one anchoring element secured to the platform on the second lateral side, a first deflector mounted to the platform thereabove to be partially in the opening near an intersection of the front and second lateral sides; and a second deflector mounted to the platform thereabove to be partially in the opening near an intersection of the front and first lateral sides. The second deflector is shifted towards the back side relatively to the first deflector so that, when the boat moves within the opening, it is forced in a parallel relationship with the dock by its contact with the first and second deflectors.
