I totally disagree with amit and shiyas because the force [thrust] acts on a body[boat] in a perpendicular direction.

It will move in opposite direction. But the thrust produced by the fan should be greater than the weight of the boat.

Question is not appropriate!
If the fan is attached to a boat and directed toward its flaps. Then it will not move.

If its so, on what principle do hovercraft run, I think its the fat that pushes the air back. Isn't it?

Air is less denser than water. So large fan is needed. Otherwise it must be a hovercraft.

May be because it doesn't create such impact to move boat. Air just work as regular fan.

Fan attached with helicopter lifts the helicopter upward the same way boat will move.

It will definitely moves in opposite direction in which in which air is blown.
