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

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.

Excellent description and explanation in non-US vessels the term 'shackle' is more used than 'shots' other than that all is the same.
Good Watch.
Capt Boucher - Thank you for your kind comments, it is appreciated. You're right of course about the terminology, I hadn't thought of it.
Note that the anchor-shackle type-D is the wrong way. The bolt should go through the crownshackle installed on anchors shank.
But its a common mistake :)
Superb explanation as well as description within non-US yachts the word 'shackle' is actually much more utilized compared to 'shots' apart from that just about all may be the exact same.
