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

See practically take a fan tag it on small boat definitely it moves.

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?

The correct question should be on a stationary sail boat, air is blown (at the sail) from a fan attached to the boat. The boat they miss the main detail.

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

Why a helicopter will fly but boat will not?

In both case there is a fan making a force in opposite direction.
