On our sailing trip north this year, we encountered a lot of cruiseships. They are gigantic (nearly 1000 ft/300 m long). There is really no land vehicle equivalent to a cruiseship. It is intimidating to encounter one on the water.
Imagine for one second that you're driving on the road, then a big ass thing on wheels suddenly arrives behind you, fast. Because it has the right of way, and that it has limited maneuverability, you have to make sure you're not in its path.
Scary.
To make matters worse, these intimidating beasts always have very cutesy names.
Like... Sapphire Princess.
