Nautilus knocking St George into the water

Nautilus slammed into him. One thick arm wrapped around St. George’s back, squeezing his ribs. The other one came down again and again, driving punches into his face. They wrestled in the air before St. George realized the ship’s hull was next to them. Nautilus twisted around, and the Pacific Ocean crashed into St. George’s back.
Much like he’d heard, hitting the water from a great height was like hitting pavement or concrete.
The waves closed over him, and the sound of wind vanished. Nautilus grabbed the lapels of St. George’s biker jacket and dragged him through the water. The cold pressed in on him. The sunlight dimmed.
They were going deeper.
