En-route to Port Kembla

Our ship was en-route to Port Kembla carrying iron ore from Port Hedland, Australia. It takes 15 days to reach Port Kembla aboard a ship. We are delivering iron ore from Port Hedland to Port Kembla. I was excited to Port Kembla because they say that place is a city I can buy anything I want. When we began the sea passage winter season is near the sea's are rough and confused causing our ship to roll/pitch and heave continuously. I didn't feel good of what's happening I get dizzy and there are times you want to puke. Sometimes when the visibility is clear I saw a group of whales besides our ship. They say whales/dolphins likes to play with ships. They are trying to outrun the ships. 

 3 days before we arrive at Port Kembla my Seniors Officers and I saw our ship travelling inside the rainbow. That moment was my first time to see a Rainbow that close. When I saw this Rainbow ahead of us I am amaze. We are joking that we might be in other dimension or take the treasure chests in the rainbow once we passed inside. I takes about half an hour before it fades. I made a research how rainbow forms, the Wikipedia says "phenomenon that is caused by reflection of light in water droplets in the Earth's atmosphere, resulting in a spectrum of light appearing in the sky". I am hoping to see more magnificent events to happen.
