The bow of a ship with headway is steadied by the anchor regardless of which anchor is used, and is not pulled in any particular direction. 

For the anchor to be most effective an amount of chain equal to about twice the depth should be put well in the water and the brake screwed up tight. 

Should the anchor be required during a maneuver, let go only enough chain to allow the anchor to first grab and then break loose and drag. The anchor must not dig in and hold. 

When using a kedge anchor in an emergency, it is especially effective for stopping a ship in a short distance while maintaining her heading, and holding the ship laterally after headway is lost. It is an appropriate tool to work the ship around a bend.

The anchor is called the “Poor man’s tugboat” for good reason. It is often more effective than a tug.
