Eli5 Why the biggest boats are so much bigger than the biggest land vehicles.

Question

I was thinking maybe because the ocean is a lot flatter than a lot of terrain but there’s also large waves and storms and sea. I also can’t imagine that something like an aircraft carrier would be significantly less complicated or difficult to build than an equally sized land vehicle.

Answer 1

In the ocean, the water supports the weight of the ship.

On land, the wheels/tracks have to support the weight of the vehicle.
