The design is wave piercing / longer water line and more initial volume forward so the bow doesn't dig in as much. These are popular on high performance cats and even modern (and much older / Great White fleet) Navy ships.
Definitely performance oriented and looks cool!
Tumblehome wave piercing hullA return to a hull form not seen since the Russo-Japanese War in 1905, the Zumwalt-class destroyer reintroduces the tumblehome hull form. Originally put forth in modern steel battleship designs by the French shipyard Forges et Chantiers de la Méditerranée in La Seyne in Toulon, French naval architects believed that tumblehome, in which the beam of the vessel narrowed from the water-line to the upper deck, would create better freeboard, greater seaworthiness, and, as Russian battleships were to find, would be ideal for navigating through narrow constraints (canals).[53] On the down side, the tumblehome battleships experienced losses in watertight integrity and/or stability problems (especially in high speed turns).[54] 21st century tumblehome is being reintroduced to reduce the radar return of the hull.
The inverted bow is designed to cut through waves rather than ride over them.[49][55] As mentioned above, the stability of this hull form in high sea states has caused debate among naval architects. The tumblehome has not been featured in USN concept designs since the Zumwalt class.
