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

The biggest land vehicles are limited by the weight they can carry and the amount of friction they create with the ground. Boats are not limited by these factors because they float on water.
