Abstract

The invention provides a shallow-draft rapid-flow route segment passenger ferry which comprises a ferry body and a building on the ferry body, the building on the ferry body is arranged on the ferry body, the prow of the ferry body is a longitudinal flow prow, the stern of the ferry body is in a round bilge line shape, and the bilge of the ferry body is higher than the lowest point of the bottom of the ferry body. The middle part between the bilge of the ferry body to the ferry head is a dipper-shaped member. And the bilge of the ship body is gradually transited to the stern to form a flat bottom. Compared with the prior art, the ferry has the following beneficial effects that by modifying the bow, the stern and the bilge of the ship body, the resistance of the ship during sailing is reduced, and the technical problem that the sailing speed of a shallow-draft ship in a long and narrow torrent water area is difficult to increase due to large sailing resistance is solved; the technical effect of stably sailing at a high speed in long and narrow torrent under the condition that shallow draft is met is achieved.

Description

technical field

[0001] The invention relates to the technical field of river ships, in particular to a shallow-draft passenger ferry in rapids. Background technique

[0002] Most of the shallow-draft passenger ferries currently on the market have a shallow-draft flat hull shape, and the bow is a turtle-shell shape with angled angles. The bottom line of the bow (the outline of the bow bottom line) in a side view starts to warp longitudinally from midship, that is, the bow faces the ship. The transition distance of the ship's bottom line is long and the angle is gentle, and the ship's midship to the stern is a flat-bottomed round bilge.

[0003] Its molded breadth-draft ratio is larger than the captain's molded-depth ratio, and the molded breadth-draft ratio is relatively large, which will make the hull pendulum period of the ship small, sway violently, and the navigation resistance is large; while the captain's molded depth ratio is large, the ship's hull will be longitudinal...
