What is the rest of the story of the wreck of the Covenant?

In Chapter 18, David learned of the events following his capsize. Two more great waves came and toppled the ship upon the reef so that water poured in. The bedridden seamen cried out in such horror that the able bodied men hopped into the dingy and paddled to shore. Another wave pushed the ship in their pursuit but was soon pulled under and sunk to the bottom. The seamen rowed silently to the shore.
