What may cause a fluctuation in the strain of the anchor chain?

Fluctuations in the strain of the anchor chain can occur due to both strong currents and wave action. Strong currents exert a pull on the anchor chain as the underwater currents shift and change direction. This can lead to variations in the force experienced by the chain, impacting its tension. Similarly, wave action causes the vessel to rise and fall, which leads to dynamic loads on the anchor chain as the boat moves with the swells and troughs of the sea.

Both factors—strong currents and wave action—can contribute to the overall strain on the chain, creating a fluctuating environment for the anchor system. This understanding is critical for ensuring the anchor remains securely set and functions properly under varying environmental conditions.
