A sea anchor is deployed off the bow and a drogue is deployed off the stern. The sea anchor keeps the bow up to weather, a drogue is usually smaller, and allows you to move downwind while acting as a brake. Each has wide variations in the sizes used, and this affects their specific role in sea survival.
The Fouled Anchor is the emblem of the Rate of Chief Petty Officer of the United States Navy. The fouled anchor has long been the symbol of the Chief Petty Officer. In terms of the Chief, the fouled anchor symbolizes the trials and tribulations that every Chief Petty Officer must endure on a daily basis. Attached to the Anchor is a length of chain and the letters U.S.N. To the novice, the anchor, chain and letters only identify a Chief Petty Officer of the United States Navy, but, to a Chief, these have a more noble and glorious meaning. The U stands for Unity, which reminds us of cooperation, maintaining harmony and continuity of purpose and action.
