According to the different tonnage of warships, the cross-sectional shape of the bottom is also different, and the common ones are rectangular bottom and arc bottom.

Rectangular bottom

Arc bottom

Except for some special ship types and experimental ships, ordinary ships have no V-shaped sharp bottom.

The sharp V you see should be a short section of the bow.

In modern times, various types of bows are famous as follows:

The "flying shear" bow, also known as the Atlantic bow,

The upward part of the ship's bow waterline shrinks backwards, as if it were cut off, to improve the stability when driving in bad sea conditions. This kind of bow has become a feature of naval capital ships in later countries.

Hyperbolic bow: the bow bends forward, perpendicular to the waterline, and bends backward below the waterline to transition to the bottom of the ship;

Japan's King Kong class battleships are unique.

Spoon bow: the part above the waterline of the ship shrinks backwards, just like the cut flying shear bow;

Japanese warship Lu 'ao

Angle bow: the bow is perpendicular to the waterline, partially forming a certain angle, and leaning forward below the waterline to form a sharp angle. The sharp corners of early warships were mostly covered with hardwood iron sheets, which were used to attack underwater enemy ships.

(influenced by the early naval warfare mode). However, there are few cases of sinking enemy ships, but most of them are sinking or injuring their own ships. After elimination. Fixed attack angle

Spherical bow: This one is more individual, and the typical one is the battleship Yamato.
