Was there any anchor chain attached to the anchor in question? If there was, how long is it?
1. No chain means it probably rotted off while stowed and just fell in the ocean.
2. If it was less than the usual length for a six ton anchor, perhaps it was probably cut after trolling for cable.
3. If it has a full length of chain then it was probably run out of the chain locker. The last link in the chain locker is weakened so that if the chain runs out, that link breaks rather than ripping out the chain locker.
Thanks.
Any insight into how an anchor on the seabed could shift so as to damage a communication cable?
