How does a boat move forward into the water when the boatman presses one end of the pole against the ground?

According to Newton's Third law of motion, " When a force is applied to an object, the object also exerts the force of same magnitude in the opposite direction." In other words, There is a reaction for every action. This law is also known Newton's law of reaction. In the give figure the force  is applied on a block and the block also exerts the same force in reaction which is denoted by $$-F$

Similarly when the boatman presses one end of the pole against the ground, it means a force has been exerted and in reaction a force of same magnitude causes the boat to move forward.
