Contrary to some beliefs, a hull that is too rigid will self destruct. All raceboats are designed with a certain amount of "give" incorporated in their construction. Now, I'm not talking about a hull that flexes as much as a limp noodle, but rather one that can distribute and absorb the shock of high speed pounding without cracking into pieces.
Same goes for skyscrapers....anyone know how much built in flex and sway is exhibited by the Empire State Building on a windy day ?? !!

1/4" in either direction, for a total of 1/2" not bad for a structure that is over 1400'tall.
To stand up to the horizontal force of wind, skyscrapers need the right combination of stability and flexibility. They have to be rigid enough that the wind can't push them too far from side to side, but flexible enough that they can give a little, absorbing some of the wind energy.
In the end, they designed the towers (world trade center) so they could sway about 3 feet in either direction
