It could be tides, or waves, or wind. It could be a movement of cargo or people in the boat. It could be propulsion by oars, punts, paddles, propellers. There is not enough information to answer the question.
if the water is moving then it will exert a force on the side of the boat. Still water will not move a boat.
Terminal velocity, where the driving force = drag force from the water
Terminal velocity, where the driving force = drag force from the water
A force that could cause a object to move in a circle would be centripetal force. That is a product of mass and centripetal acceleration. It is quite a bit complicated.
The force must cause the object to move.
the pressure and force of the water.

Force can cause mass to move, it does not move in itself.
Newton's Third Law: For every force there is an equal and opposite reaction force. The boat (and man) would receive an impulse force opposite to the direction of firing. The boat would move opposite to the direction of firing. To determine how much, you would need to consider the relative masses of the boat/man vs the bullet, and include the duration of the impulse. (The boat would probably not move far, but it would move.)

The force must cause the object to move.
The force that cause Earthquakes as rocks to move and break are called plate tectonics
because the floor exerts the same amount of force which means the net force is balanced causing it not to move
When the force is great enough to overcome the object's inertia.
A force must be applied to cause matter to move.
