I have a Cutwater 30cb. with a Rocha 15, heavy duty swivel, 50ft. of 5/16 chain plus 200ft line on an Electric Windlass. I’m thinking of keeping the boat’s original 22lb claw anchor as a spare. I already have 200ft of 5/16 double braid and 15ft 5/16 chain that will match the windlass. My question is should I also add a swivel to the spare? I’ve had conflicting advice, some saying the swivel becomes a weak link.
