St George catching an anchor, Nautilus yanking St George

He pushed himself out of the wreckage just in time for the anchor to rush at him. He got his hands up and caught it, grabbing hold of the shaft. A thousand pounds, easy, with a lot of momentum behind it.
Nautilus jerked on the chain and yanked St. George off his feet. The hero sprawled forward on the yacht’s deck, but didn’t let go of the anchor. Nautilus snapped the links like a whip, and the big piece of iron thrashed in St. George’s hands. Another lash of the chain tore the anchor away.
