Which type of anchor is noted for its relatively weak holding power?

The mushroom-type anchor is designed with a rounded, umbrella-like shape that can easily penetrate soft bottom substrates like mud or sand. However, its design leads to a relatively weak holding power in comparison to other anchor types. This is because once it is set, it relies on the weight of the anchor to hold it in place but does not provide the same level of grip on the seabed as fluke-style or plow-style anchors.

Mushroom anchors are typically better suited for temporary mooring or for use in areas where the anchoring conditions are soft and suitable for this type of anchor. Their limited effectiveness in harsher conditions or harder substrates is why they are often perceived as having weak holding power compared to the other anchor types that feature more aggressive designs intended to dig in and secure better in a wider variety of conditions.
