How does a fluke-style anchor secure a recreational boat?

A fluke-style anchor secures a recreational boat primarily by burying itself into bottom sediments. This type of anchor is designed with one or more flat, pointed flukes that help it penetrate into the soft material at the bottom of rivers, lakes, or oceans when pressure from the weight of the boat is applied.

As the boat is subjected to wind or current, the flukes dig further into the sediment, improving the hold of the anchor and increasing stability. The effectiveness of a fluke-style anchor comes from its ability to create friction and resistance, locking itself into place within the sediment rather than simply resting on the surface. This method of anchoring is especially useful in soft or muddy bottoms where the anchor can achieve a strong grip.

The other options do not accurately describe the function of a fluke-style anchor. For instance, floating on the surface would not provide any security for the boat, and tying firmly to the hull would pertain to mooring rather than anchoring. Additionally, relying solely on engaging the water's current is not effective for securing a vessel, as boat stability requires a firm hold in the seabed rather than movement with the current.
