Louisiana Boater Safety Practice Exam

The main feature of a plow anchor is its ability to gain holding power by plowing into the bottom sediment. This design allows the anchor to bury itself deeper into various types of seabed conditions, which enhances its grip and stability. The plow shape helps it to cut through sand or mud, providing a secure hold even in challenging conditions like strong currents or windy weather.

While lightweight design can facilitate handling, it does not define the functionality of a plow anchor. Additionally, although larger boats commonly use plow anchors due to their increased effectiveness in deeper waters, they are not exclusive to that category; smaller boats can also benefit from their holding power. The circular design mentioned is characteristic of other types of anchors, such as grapnel or mushroom anchors, but plow anchors typically have a more pointed structure to aid in their plowing action.
