[0017] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model. Embodiment

[0018] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a super high-speed boat hull form, including a hull 1 and a deck 2. The deck 2 is installed on the hull 1, and a cockpit 22 is formed on the deck 2. The hull 1 includes a bow 13, a hull body 12, and a stern 11. The bow 13 to the hull body 12 is streamlined, and the bottom surface of the stern 11 is stepped, successively including a downwardly convex stern seal plate 111, a first step 112, and a second step 113. The bottom surface of the first step 112 is higher than the stern seal plate 111, and the bottom surface of the first step 112 is also higher than the second step 113. The bottom surface of the second step 113 is higher than the bottom surface of the hull body 12. A propeller motor is provided on the stern 11, and the propeller motor is located on the first step 112 and the second step 113. During driving, the bow 13 will tilt upward, while the stern 11 will be immersed in water. By using the first step 112 and the second step 113 whose bottom surfaces are higher than the hull body 12, when the hull 1 tilts, the first step 112 and the second step 113 will be located within the liquid surface, increasing the resistance between the steps and the liquid surface, reducing the occurrence of side-slip phenomenon. At the same time, the bottom surface of the downwardly convex stern seal plate 111 is lower than the first step 113. When the hull 1 tilts, the stern seal plate 111 is also located within the liquid surface, improving the damping of the hull 1 during side-slip and fishtailing, reducing the occurrence of side-slip and fishtailing, and improving the controllability of the hull 1.

[0019] The hull body 12 includes side walls 121 and a bottom plate 122. The bottom plate 122 is distributed in a V shape, and the angle between the bottom plates 122 is an obtuse angle. In this embodiment, the angle between the bottom plates 122 is 139°. A folded line structure 123 is formed between the bottom plate 122 and the side walls 121. The folded line structure 123 slopes downward from the inside to the outside, further increasing the contact area with the liquid surface, enhancing the buoyancy of the hull body 12. At the same time, the folded line structure 123 can improve the rolling of the ship and enhance the stability of the ship during high-speed operation.

[0020] The folded line structure 123 is distributed at an angle of 5° with the horizontal plane, and the folded line structure 123 and the side walls 121 are distributed at an angle of 100°, effectively reducing the wave-making resistance and being beneficial to increasing the ship speed.

[0021] A partition 114 is also formed inside the stern 11. The partition 114 is located inside the stern seal plate 111. The partition 114 is used for positioning and supporting the installation of the propeller, ensuring the strength of the propeller installation and further ensuring the stable operation of the propeller.

[0022] An entrance 3 is opened on the deck 2, and the entrance 3 is communicated with the cockpit 22.

[0023] A boss 21 is also formed on the deck 2. The boss 21 is located on the stern 11. The side surface of the boss 21 is used for installing a guardrail, and the boss 21 is used for positioning the installation of the guardrail.

[0024] The lengths of both the hull 1 and the deck 2 are 14.5 m, the width is 3.6 m, the molded depth of the hull 1 is 1.95 m, the displacement reaches 16.2 T, and the draft is 0.8 m.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
