Which type of anchor is commonly used for sandy bottoms?

The fluke anchor is commonly used for sandy bottoms due to its design, which allows it to set effectively in this type of substrate. The flukes create sufficient surface area against the sand, allowing the anchor to dig in and gain a holding position when tension is applied. This design is particularly advantageous in sand because it can penetrate and hold firmly, providing stability for vessels.

Fluke anchors often have a lightweight construction, making them easy to deploy and recover, which is practical for use on sandy bottoms where frequent repositioning may be necessary. Additionally, their effectiveness in sandy environments ensures that vessels remain securely anchored, even in changing conditions such as tidal shifts or currents.

In contrast, other anchor types are better suited for different substrates. Plow anchors are versatile but excel in mixed or harder bottoms, grapnel anchors are less effective for holding capacity, primarily intended for retrieving items rather than anchoring, and deadweight anchors rely on sheer weight without penetration, making them less effective in loose sandy substrates.
