A few details about the ground tackle of a 6500 unit PCTC (Pure Car Truck Carrier or informally a car carrier) - a 200 meter ship
On all ships the term ground tackle refers to a vessel's anchors, chain and windlass.
The anchor: The anchor type is AC-14 The weight is about 8 tons
|Ship's anchor chain ranged out onto the drydock|
The port anchor chain is 11 shots - 990 feet or about 300 meters - total weight is 44 tons.
The starboard anchor is 10 shots - 900 feet or about 274 meters - total weight is 40 tons.
The weight of a 81mm diameter chain is 0.144 tons/meter - the weight of each shot therefore is 4 tons.
Each shot is connected by a connecting link.

The windlass: There are two separate, hydraulically powered windlass, one for each side, the windlass is capable of recovering the chain at a rate of about 1 shot (90 feet) in three minutes.
Scope refers to the amount of chain used at anchor - that will be the next post: Scope - Amount recommended for anchoring.
