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

It depend upon the angle of fan.

A sailboat is a boat propelled partly or entirely by sails. The sail neutralizes the thrust produced by FAN so the boat won't move.

A stationary sail boat does not move because the boat is tight with a rope.

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

Why a helicopter will fly but boat will not?
In both case there is a fan making a force in opposite direction.

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

Dear friends, if the fan is operated through electricity, then that extra electric energy must show some effect when it becomes mechanical! by law of conservation of energy.
