I have a 20 ' sailboat weighing about 2,100 pds. I"m using 15 ' of 1/2 inch braided line as my pendant, but was wondering is a 3/8 anchor shackle and swivel, both rated at 2,000 pds sufficient to connect to the chain? Anything bigger cant connect to the chain. I'm using a 3/8' chain from the buoy down to the anchor which is the min requirment in NY.
