Anchor
An anchor is a device, normally made of metal, used to connect a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin "ancora", which itself comes from the Greek ἄγκυρα ("ankura").
Anchor Step
Different types of anchors will leave the partners in one of three positions:
1) the dancers are not individually centered (with an away resistance), resulting in a heavy active connection (sometime referred to as leverage; 2) partners will be individually centered, resulting in a passive connection; 3) the follower's center point of balance will be slightly forward of being individually centered - resulting in a passive connection.
