Just been playing this with my lad, it's called Youda Marina and it's a free game online... Have fun!

Build your dream marina and run the coolest coastline ever.
Your goal is to either focus on creating an efficient working harbor or produce the most beautiful marina in the world.
You are the harbor master, responsible for keeping all your Marina visitors happy. And happy visitors mean lots of income as they pay their harbor fees and visit your bars and restaurants.
The more income you earn, the more you can build, and the more incredible your Marina will be!
