We may simply add the length of the anchor cables used and the length of the ship together in estimating the radius of the turing circle of a ship at anchor.
General manoeuvring characteristics of merchant vessels of all types; Definitions of terms: turning circle, advance, transfer, drift angle, tactical diameter, track reach, head reach and side reach; Turning circles of a ship in the loaded and ballast conditions, at different speeds; Accelerating turn and decelerating turn; Stopping distances in loaded and ballast conditions; The effect of shallow or deep water on the turning circle; Directional stability.

This is because the depth of the water has a significant effect for the maximum turning circle of an anchored vessel. In shallow water, the anchor chain has longer catenary than in deep water when the length of the chain laid out is the same. And so, to minimize its turning circle, the anchor chain laid out in shallow water should be less than in deep water. Normally, in moderate weather condition, determining the right lenght of the chain to be paid out is by getting the depth of the water and multiply it by 3-5 times. In bad weather condition, multiply it by 5-8 times or more.

It should be moving forwards or backwards.
it is determined by the length of the shackle passed into water,in addition to the length from the for'd perpendicular to the bridge.sum of these two are known as the swinging circle of the ship.it is radius at which the ship rotates with anchor as the centre.the radius will not exceed the sum of the lengths.it is important to check time to time whether the anchor is dragging or not.swinging circle should be closely watched when the ship's are nearby.swinging circle can be reduced by standing moor.
