Pouring anchor Kenter shackle lead plug - GIF

[mklotz]

Recent aircraft carriers are fitted with 12 shots (180 fathoms, 1080'), at about 10,000 pounds per shot these are very close, if not same size links. Critical to retrieve a 30 ton anchor.

Leagues, fathoms, and now shots. The seafaring community has to accept the blame for some of the more contorted measures of the inferial system.

Am I correct in assuming that the shackles are used to connect 90 foot lengths of chain ? So, each time a shackle shoots by, you count one shot ?

How did the term 'shot' arise ?
