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.
If the anchor is old and rusted or the chain and rope is broken the chances of the ship drifting increases many fold. We hope by reading this article you will get a good idea of how does a ship anchor work. Even for fishing boat owners, anchoring is a skill that all must know when they are heading to the sea.
