What type of bottom should be avoided when anchoring?

When anchoring a boat, it is advised to avoid grassy bottoms due to the way the anchor engages with the substrate. Grass can create a barrier that prevents the anchor from properly digging in or holding securely. When a boat is anchored in grass, the anchor may not have enough surface area to latch onto a solid surface below and can pull free easily with tidal changes or wind gusts, leading to dragging or even a complete loss of the anchor.

On the other hand, choices like sand and gravel or soft mud typically provide a good hold for anchors because they allow the anchor to dig in effectively. Clear rock can also provide a stable platform, although it may be more challenging to retrieve an anchor from a rocky seabed. Therefore, understanding the characteristics of different underwater bottoms helps in selecting an appropriate anchoring spot for enhanced safety and stability.
