What is the function of a sea anchor?

• A. To slow or control drift in heavy seas and maintain steering control at low speeds.
• B. To anchor permanently.
• C. To raise the anchor.
• D. To stop the boat.

Answer: (A)

A sea anchor functions as a drag device to manage how a vessel moves in heavy seas. By creating significant resistance in the water, it slows the boat’s drift and makes steering easier when you’re moving slowly or have limited control from the helm. This helps prevent dangerous broaching and keeps the vessel pointing into the waves, reducing pounding and sustaining better handling when wind and waves would otherwise push you off course. It’s not a permanent anchor to the bottom, it doesn’t raise the anchor, and it doesn’t stop the boat entirely; it simply adds drag to limit motion and improve control in rough conditions.
