Why is it best to avoid anchoring from the stern alone?

Anchoring from the stern alone can lead to instability and an increased risk of capsizing, especially in rough waters or strong currents. It can also cause the vessel to swing unpredictably, making it difficult to maintain a safe position. Additionally, stern anchoring may not provide adequate holding power, as the bow can be pulled toward the anchor, compromising the boat's overall security. For these reasons, it's generally safer to use a bow anchor in conjunction with a stern anchor when necessary.
