Re: Re: Shapes
They used to call that a "Skipjack" hull, after the first submarine that adopted that teardrop shape. Before that, all subs had "boat" shapes, since the older subs spent a lot more time at the surface. I understand the new subs roll a lot on the surface.
The stern plane, the horizontal portion of that "cross" shaped fin set, has its own vertical stabilizer. This stabilizer is still submerged in the video (you can see the tip of the taller central vertical fin/rudder in the backwash). But it must have cut the tug's hull open like a knife.
