Hull structure

A hull structure comprising:

• a chine serving as a boundary between a broadside of a hull and a bottom thereof, wherein:
• the hull has a configuration wherein:
• the hull has a maximum depth in a vicinity of a central position of the hull;
• the chine is provided so that its level position becomes gradually lower from a bow side toward a stern side;
• and
• the bottom has a cross-section having a substantially V-shape from the bow toward the stern, the V-shape having an inner angle becoming gradually smaller within a range of from about 80° to 100° from the bow toward a central portion of the hull becoming gradually larger from the central portion thereof toward the stern and becoming about 180° at an end of the stern and a vertical distance extending between a first horizontal line passing through the chine and a second horizontal line different from the first horizontal line passing through the lowermost portion of the bottom located directly below the chine, the vertical distance becoming larger from the bow side toward the central portion of the hull and becoming smaller from the central portion of the hull toward the stern.
