What would you do? #2

You are on a small cruise ship and there is a massive storm approaching. Your captain decides to take a route around the storm but leads you into shallow waters . About half and hour into the journey through the shallow waters your boat hits a huge rock and the hull is breached. The ship is immobile. Suddenly the situation takes a turn for the worst. The storm starts to move towards the ship. The waters rise and the ship is 3/4 underwater. Panic breaks out amongst the ships passengers. You see two islands in the distance. One island is fairly close and has what looks to be a cave. The second island is further away but is larger than the first island and has what looks to be a lighthouse. By now the storm is nearly there.
Comment below what island you would go to and what you would do!
