Why is a soft bottom of mud and clay the most suitable for anchoring?

The soft bottom of mud and clay is particularly suitable for anchoring because it allows the anchor to dig in effectively. When an anchor sets in a soft substrate like mud or clay, its flukes can penetrate deeper into the material, creating a secure hold. This digging action increases resistance against the pull of wind and current, which is crucial in preventing the vessel from drifting.

In contrast, harder bottoms, such as sand or rocky substrates, may not allow the anchor to bury itself adequately, leading to potential dragging. While retrieval can be easier on softer bottoms because the anchor may not be as firmly set, the primary advantage of soft mud and clay is indeed the ability for the anchor to establish a more secure and stable position by digging in, ensuring better holding power.
