Does it fuck.
It's not actually a boat; it's a concrete and steel building with some cladding to make it vaguely boat shaped. It would float about as effectively as the Empire State Building; Except that the ESB would stay above the surface longer by dint of being taller.
If someone built an actual wooden ship of that size, it would
probably float as long as the water was dead calm; assuming that it was built with enough internal bracing (which would leave very little payload space below decks). In even the smallest swell, a ship of that size built from timber would break up and sink in seconds.
