A closer look

If you've ever looked at a modern mega-ship out of the water, it looks like it has a terrifyingly giant tumor on its face. This 'bulbous bow' is actually a stroke of hydrodynamic genius. As the ship moves, the bulb creates its own specific wave that neatly cancels out the natural bow wave the ship generates. By flattening the water around the hull, it drastically reduces drag, saving the cruise line millions in fuel costs while completely ruining the ship's profile.
