what happened on january 2? explain

When the wave walker first set out, the sea was calm and quiet. The first phase of the journey was pleasing. However, on their second day in Cape Town they began to run into strong windstorm which grew worse day by day. On 2nd January, the waves became massive and it was an ominous sign. A threatening silence prevailed in the atmosphere. The wind went down and the sky grew dark. It was a small ship and so they tried to manage its speed in the face of those catastrophic waves. The huge waves tossed and crashed on the deck of the ship. The waves rose to great height, vertically. The narrator lost his stability and was knocked down. He hit the wheel and thus fell unconscious. He was thrown in the overboard repetitively due to waves and was injured very badly. His ribs cracked and blood started coming out of his broken teeth. All the members tried to pump out the water but to no avail as the pump got blocked due to the debris. They took the help of a second electric pump which was under the chatterbox. They all were injured severely after this incident.
