Forget the fact that all boats are built today with comparable floatation, let's just look at the holes.
If I took a styrafoam cooler, filled it with water it would sink down to about....here, right? Water in the cooler will hold it down to a certain level, however if I cut a hole in the bottom of the cooler, what happens? Does it sink? No, in fact it raises up, because the trapped water is now allowed to escape, and the cooler pops up to it's normal floatation level. No difference in a hull with floatation in it.
If you took that lemming wagon, left in the plug, NO HOLES, and filled it full of water, it would sink to the gunnels, because the water couldn't escape. That boys and girls is why they cut the holes.
Every current boat would do exactly the same, you can just take the plug out and see similar results. Whoop de freaking deal. But, it sure sells boats to the weak minded.
