Captain Jack Sparrow has spent all his life out in the ocean, basically. He started sailing when he was very young and became a captain very young as well. He has fought many battles, faced many foes, dealt with many storms.
But none like this storm. This storm has to be the hardest one he's ever gone through. He was struggling to keep his ship straight. A few men had even fallen off. Many times he's had to retrieve his hat.
He kept giving out orders to keep the ship afloat but it was hard to hear him over the rain and the crew freaking out. Captain Jack tried a few times to go and help them in the deck but he just couldn't leave the wheel, he had to keep the ship from just going everywhere.
They were doing a decent job until one huge came up and started to come down. Captain Jack tried to steer the ship away from the wave but he wasn't able. The wave hit the ship and down they went.
His memories were fuzzy after that. Next thing he knew, he was waking up on an island with the sun shining down on him.
