I think they mean the inverted bow ? If you plow into a wave it cuts through rather than lifts the front. This design is more economical in heavy seas.
Ah no. I should have known.
I do have a belly and an ogive shape abaft as well.
Ogive can mean concave as well as convex. I guess they mean concave here, judging by the middle picture. I'd think that would only work for speed boats but not for ships over 200 meter long, unless it travels at 80 mph or more?
