Embodiment Construction
[0017] The present invention will be further described below with reference to specific examples and accompanying drawings.
[0018] The present invention provides a shark fin bow structure, such as figure 1 As shown, this structure includes an upper part 1 and a lower part, and the lower part is a bulbous nose 2; the front end of the upper part is perpendicular to the sea level, extends upward to the surface of the bow of the hull, connects to the bulbous nose 2 downward, and is connected to the hull light backwards. Connect along.
[0019] figure 2 It is a side view of the prior art ship shape, and there is a depression between the upper part 3 of the prior art ship shape and the bulbous nose 2; such as image 3 As shown, an improvement is made on the prior art ship type, and the upper part 1 of the present invention is added as an appendage structure; such as Figure 4 As shown, the left half is the front view of the prior art ship type A, and the other half is the fron...
