Top end tethering

[zoidberg]

Or should that be 'Bottom end tethering'...?

This pic, from Defense Media, shows an Astute Class submarine taking a tow from a passing helicopter, while preparing to anchor. I note the 40mm Anchorbraid rode and wonder A: what type of anchor is the current favourite, and B: what scope of Anchorbraid is preferred and whether there's a short length of 10mm chain on the far end?

I'm sure there are some long-retired submariners 'on the beach' hereabouts, remnants of last century's Oberon fleet, who may have the answers

Submarines all use an Admiralty pattern fisherman’s anchor as these have been proven in tests to have a much higher holding power than Knoxes, Rocnas and the like . It has been found that the most important part of the gear is the anchor swivel and provided that’s fitted, then a short, 5m length of 10mm chain together with 24mm anchorbraid is quite sufficient.

It’s also been found that the deeper the submarine is dived when it anchors, then the scope needed is less.

Practicing medical evac or some other sort of transfer?

Astute didn't need an anchor when it "visited" the Isle of Skye.
