Secondly, the best criticism is the things you've done wrong. Saying "this is fantastic" is pretty much always a lie and will not help you improve. So, keep that in mind, don't let it hurt your feelings, and - most importantly - keep writing! As it's short, I'll break it down bit by bit.
Also, everyone knows that England is a country and London is a city, unless there is something severely wrong with you. You don't need to clarify it.
The last sentence is something that would take a long time to explain why it's bad in full detail, so I'll do my best to make a long story short. This is what you should slowly reveal throughout the novel, not what you should explain right at the start. To give an example - if you own the first Harry Potter book, pick it up now. If you don't, get it from a library. Find the part where J.K. Rowling writes
"Harry would make two close friends, Ron and Hermione. Little did they know, this friendship would be tested over many years."
Did you find it? That's because it's not there. It takes her an entire series of books to tell us that.
Also, a storm changing from 'calm' to 'violent' in a short amount of time is pretty much the dictionary definition of a storm. You wrote that a storm was brewing, and then you wrote it again, but with more words.
It's a somewhat difficult concept to understand, but most of a story takes place off the page. The author, essentially, gives as few prompts as possible for the reader to conjure up an image in their head. 'A storm started brewing' is enough for the reader to then infer the rest.
This is good. It's descriptive, it's exciting, it takes place directly in the action. I like this. Just carrying on what I said above, "making all the passengers sick" doesn't need to be there. If it really does need to be there - show, don't tell. Show us someone vomiting, or holding their mouth, or leaning over the side. That's much more exciting than "they were sick."
I'll leave it there because the last part is as equally weak as the other parts, but I've already mentioned why. Keep it up, you can only improve with practice.
