Page "Anchor" Paragraph 71

In yachts, a kedge anchor is an anchor carried in addition to the main, or bower anchors, and usually stowed aft.

Every yacht should carry at least two anchors – the main or bower anchor and a second lighter kedge anchor.

It is used occasionally when it is necessary to limit the turning circle as the yacht swings when it is anchored, such as in a very narrow river or a deep pool in an otherwise shallow area.
