Why do ships have anchors?

Answer: Hold position in shallow water

Emergency brake when engines fail — Wrong. Anchors can't stop a moving ship quickly—they drag. Anchors hold stationary ships in place, especially in harbors or shallow water.

Stabilize ship during storms — Wrong. In storms at sea, ships often raise anchors and use engines to maneuver. Anchors work in shallow water to maintain position, not for storm stabilization.

Hold position in shallow water ✓ — Correct! Anchors hold ships in position when stopped, particularly in harbors, bays, or shallow water where the anchor chain can reach the bottom. The anchor's weight and shape dig into the seafloor, and the chain's weight provides holding force. Ships can 'park' without drifting.
