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.

Draw length is the distance that the string will travel from its original position to your anchor point when you have fully drawn the bow. this will obviously vary for different people. so your draw length will be personal to you. depending on anchor point length of arms etc etc. one way to measure it is to use a stick and place one end on your anchor point and get someone else to measure the length to the tips of your fingers, add one inch for safety
1 shackle = 15 fathoms = 90 feet A unit of length used for anchor chain on ships. Anchor chains for ships are made up of 15-fathom lengths of chain joined by detachable links. The joins are distinctively marked so a ship's officer can estimate at a glance how much chain is out. In the merchant marine, the detachable links are painted red. At 15 fathoms, the end of the first shot, the two links on either side of the detachable link are painted white, and 1 turn of wire is wound around the stud of the link on either side of the detachable link. At 30 fathoms, the 2 links on either side of the detachable link are painted white, and 2 turns of wire are put on the second stud on either side of detachable link, and so on for the remaining shots. In the merchant marine, in the command to let go the anchor the amount to be played out is given in shots; in the Navy it is given in fathoms.1
