From the ground level, the top floor of Marina Bay Sands hotel looks like a ship or an ark that's rested on top of the 3 buildings.
From the top of Republic Plaza, you can see there is another building (foreground) that looks like a ship too. They all seem to be heading for collision, if one does not change course.
The real ships are out at sea, there are so many of it, that you will lose count!
To me, the best view of the ships out at sea is when you are flying into Singapore at night. When the plane is flying very low, making a turn to land at Changi Airport.
