Anchors are heavy objects used to secure a vessel to the sea floor, preventing it from drifting due to wind or currents. They typically consist of a metal shank with flukes that dig into the seabed when dropped. The weight and design of an anchor determine its holding power, making it essential for boats and ships to remain stable in various water conditions. In addition to marine use, the term "anchor" can also refer to a metaphorical concept in psychology, where it represents a stable point of reference in a person's life. This can include relationships, beliefs, or experiences that provide security and comfort during challenging times.
