I believe it keeps the bow into the wind and or waves to help keep from getting sideways and rolling over, a bucket will help pass as a sea anchor. It will also help slow down (mph) when trolling with a larger engine.
In a storm a sea anchor can help a vessel from drifting off course. It will keep the bow in the wind and slow the speed of the vessel.
Drop a sea anchor off the bow.
Deploy a storm anchor (sea anchor) from the bow; something that will slow the boat's drift downwind. Something like a small drogue parachute in the water. The wind will cause the boat to drift, and the waves to rise; the storm anchor will slow down the drift, and keep the boat pointed into the wind. Bow-on is the safest direction for your boat to meet the waves. Otherwise, the wind would tend to push the boat sideways, and you could easily capsize.

The position of an anchor just clear of the sea floor is called the "anchor rode." This term refers to the length of chain or rope that connects the anchor to the boat. When the anchor is properly set, it should be resting on the sea floor while the rode holds the boat in place.
Held fast by or as if by an anchor. An anchor is a heavy object dropped by a boat which embeds itself in the sea floor and thus provides a mooring to which the boat can be secured.
Well in Christianity it is part of a metaphor that life is like the sea and you are a boat, when a storm comes along your love for God can keep you anchored in place ( to be steady and not sink or be broken on rocks).

No, a sea anchor is not effective against current. Sea anchors are used to stabilize a boat in rough seas or high winds by creating drag, but they do not significantly impact a boat's movement in a current. Other methods, such as using the engine or drift socks, are more effective for managing current.
If your boat is caught in a storm and the engine stops, immediately assess the situation and ensure that all passengers are wearing life jackets. Try to secure the boat by deploying anchors or using a sea anchor to maintain stability and prevent drifting. Monitor the weather and waves, and if possible, use oars or paddles to maneuver the boat to safer waters. Lastly, communicate your location and situation to emergency services if you have a radio or phone available.
A sea anchor, also known as a drift anchor, is used to stabilize a boat in rough seas or heavy winds by creating drag in the water. It slows the vessel's drift and helps maintain a more stable orientation, reducing the risk of broaching or capsizing. Proper use involves deploying the sea anchor from the bow to keep the boat facing into the waves, ensuring that it remains secure and minimizes movement. It's essential to monitor the conditions and retrieve the anchor when conditions improve or when navigation is required.
