[0021] In the description of the present disclosure, front side and front refer to the bow side and a direction toward the bow based on the center of the hull, and rear side and rear refer to the stern side and a direction toward the stern based on the center of the hull.

[0022] Also, in the description of the present disclosure, directions such as upward and downward are only indicated based on the form of FIG. 1 to assist understanding, and it should be noted that the directions may be differently indicated when the reference line (or drawing) changes.

[0023] The present disclosure relates to a rolling reduction boat, and more particularly, to a rolling reduction boat having a structure that allows a rolling reduction tube, which is formed to surround a boat main body, to be filled with water during sailing of the boat.

[0024] FIGS. 1 to 3 are perspective views of a rolling reduction boat according to the present disclosure, FIG. 4 is a lateral view of the rolling reduction boat according to the present disclosure and shows a state before a water injection member is coupled to a coupling protrusion, FIG. 5 is a lateral view of the rolling reduction boat according to the present disclosure and shows a state after the water injection member is coupled to the coupling protrusion, FIG. 6 is a cross-sectional view along line A-A of FIG. 1, FIGS. 7A to 7C are cross-sectional views along line B-B of FIG. 1 and show a state in which a rolling reduction tube is not filled with water, FIGS. 8A to 8C are cross-sectional views along line B-B of FIG. 1 and show a state in which the rolling reduction tube is filled with water, FIG. 9 is a cross-sectional view along line C-C of FIG. 1 and shows a state before a passenger scoops and pours water using a water injection member, FIG. 10 is a cross-sectional view along line C-C of FIG. 1 and shows a state in which the passenger scoops and pours water using the water injection member, and FIG. 11 is a lateral view of the rolling reduction boat according to the present disclosure and shows a state in which the passenger gets on the boat using a rope ladder.

[0025] As illustrated in FIGS. 1 to 3, a rolling reduction boat according to the present disclosure may be configured by including a boat main body 100, rolling reduction tubes 200 and 200, a tube connection member 300, a water injection member 400, a coupling protrusion 500, an extension member 600, a pitching prevention member 700, and a rope ladder 800.

[0026] The rolling reduction tubes 200 and 200 will be described. The rolling reduction tubes 200 and 200 are portions formed to surround a side portion of the boat main body 100 and are portions filled with water to prevent rolling of the boat main body 100.

[0027] In other words, as the rolling reduction tubes 200 and 200 are filled with water, the degree to which the boat main body 100 tilts or rolls is reduced, and a restoring force of the boat is increased.

[0028] The rolling reduction tubes 200 and 200 may be configured by including opening maintenance members 210 and 210 formed to surround front end openings of the rolling reduction tubes 200 and 200 to maintain an open state of the rolling reduction tubes 200 and 200.

[0029] When the rolling reduction tubes 200 and 200 are formed of a rubber material, the open front ends thereof may be rolled inward, and in this case, it is difficult for water to be injected into the rolling reduction tubes 200 and 200. Therefore, the opening maintenance members 210 and 210 are used to maintain the rolling reduction tubes 200 and 200 in an open state.

[0030] A state in which the rolling reduction tubes 200 and 200 are not filled with water L is illustrated in FIGS. 7A to 7C. That is, referring to FIGS. 7A to 7C, when the rolling reduction tubes 200 and 200 are not filled with the water L, the degree to which the boat main body 100 is rolled is high, and the boat main body 100 is tilted by as much as ?1 and ?1.

[0031] This is because, when the rolling reduction tubes 200 and 200 are not filled with the water L, the overall weight of the boat is small, and buoyant forces F1 and F1 of portions submerged in water during rolling of the boat main body 100 are not large, such that a restoring force of the boat main body 100 is small.

[0032] Conversely, a state in which the rolling reduction tubes 200 and 200 are filled with the water L is illustrated in FIGS. 8A to 8C. That is, referring to FIGS. 8A to 8C, when the rolling reduction tubes 200 and 200 are filled with the water L, the degree to which the boat main body 100 is rolled is relatively low, and thus the boat main body 100 is tilted only by as much as ?2 and ?2.

[0033] This is because, when the rolling reduction tubes 200 and 200 are filled with the water L, the overall weight of the boat is relatively large, and buoyant forces F2 and F2 of the portions submerged in water during rolling of the boat main body 100 are relatively large, such that the restoring force of the boat main body 100 is increased.

[0034] These can be summed up by the following equations.

F1<F2,2)F1<F2,3)?1>?2,4)?1>?21)

[0035] The tube connection member 300 will be described. The tube connection member 300 is a portion coupled to communicate with front end openings of the rolling reduction tubes 200 and 200 and may have a water injection hole 310, through which water is injected, formed to pass through an upper side.

[0036] The tube connection member 300 may be configured by including a water injection guide member 320 formed at an inner lower side of the tube connection member 300, formed in a curved shape that is convex upward, and configured to guide water, injected into the tube connection member 300 through the water injection hole 310, to flow downward into the rolling reduction tubes 200 and 200 (see FIG. 6).

[0037] By the water injection guide member 320, not only the injection of water into the rolling reduction tubes 200 and 200 is guided, but also external leakage of water injected into the rolling reduction tubes 200 and 200 may be prevented.

[0038] The water injection member 400 will be described. The water injection member 400 is a portion formed at a lower portion of a front side of the boat main body 100 to inject water into the water injection hole 310 and may have a plate shape and extend forward.

[0039] The water injection member 400 is submerged in water when the boat main body 100 is disposed on water and is used by a passenger 1 of the boat main body 100 to scoop water and inject the water into the water injection hole 310 of the tube connection member 300 (see FIGS. 9 and 10).

[0040] FIG. 9 is a cross-sectional view along line C-C of FIG. 1 and shows a state before a passenger scoops and pours water using a water injection member, and FIG. is a cross-sectional view along line C-C of FIG. 1 and shows a state in which the passenger scoops and pours water using the water injection member.

[0041] The water injection member 400 may have a bendable material to allow the passenger 1 to easily inject water.

[0042] The water injection member 400 may be configured by including a coupling hole 410 formed to vertically pass through a front end of the water injection member 400 and configured to be coupled to the coupling protrusion 500 when the water injection member 400 is rolled upward.

[0043] The coupling protrusion 500 will be described. The coupling protrusion 500 is a portion formed on an upper portion of the front side of the boat main body 100 and configured to protrude forward and is a portion coupled to the above-described coupling hole 410 (see FIGS. 4 and 5).

[0044] FIG. 4 is a lateral view of the rolling reduction boat according to the present disclosure and shows a state before a water injection member is coupled to a coupling protrusion, and FIG. 5 is a lateral view of the rolling reduction boat according to the present disclosure and shows a state after the water injection member is coupled to the coupling protrusion.

[0045] That is, by coupling the coupling hole 410 to the coupling protrusion 500 to bring the water injection member 400 in close contact with the boat main body 100, external leakage of water injected into the rolling reduction tubes 200 and 200 is prevented.

[0046] The extension member 600 will be described. The extension member 600 is a portion configured to extend vertically downward from a lower end of the front side of the boat main body 100 and submerge in water when the boat main body 100 is disposed on water. The extension member 600 serves to connect the boat main body 100 and the pitching prevention member 700, which will be described below, to each other.

[0047] The rope ladder 800 will be described. The rope ladder 800 is a portion formed at a rear side of the boat main body 100 and is a portion used by the passenger 1 to climb up to get on the boat main body 100.

[0048] The pitching prevention member 700 will be described. The pitching prevention member 700 is a portion formed on a lower end portion of the extension member 600 and formed to be dustpan-shaped with an open front surface and an open upper surface.

[0049] When the passenger 1 climbs up the rope ladder 800 to get on the boat main body 100, the boat main body 100 is pitched due to the weight of the passenger 1, and the bow of the boat main body 100 is lifted. The pitching prevention member 700 is provided to reduce such a pitching phenomenon.

[0050] Specifically, the pitching prevention member 700 is submerged in water when the boat main body 100 is disposed on water, and when the passenger 1 climbs up the rope ladder 800, as illustrated in FIG. 11, a downward force F3 acts on the stern due to the weight of the passenger 1, and corresponding to the downward force F3, an upward force F3 acts on the bow such that the bow is lifted above the water surface.

[0051] Here, the pitching prevention member 700 is also lifted. Because the pitching prevention member 700 is formed to be dustpan-shaped, the pitching prevention member 700 is lifted while filled with water, a downward force F4 acts on the bow due to the weight of the water with which the pitching prevention member 700 is filled, and corresponding to the downward force F4, an upward force F4 acts on the stern.

[0052] That is, referring to FIG. 11, the net force of the downward force F3 acting on the stern is reduced due to the upward force F4 acting on the stern in the opposite direction, and thus the pitching phenomenon can be reduced.

[0053] Likewise, the net force of the downward force F4 acting on the bow is reduced due to the upward force F3 acting on the bow in the opposite direction.

[0054] The pitching prevention member 700 may be formed of the same material as the boat main body 100 but is not necessarily limited thereto.

[0055] The present disclosure described above is not limited by the above-described embodiments and the accompanying drawings, and it should be apparent to those of ordinary skill in the art to which the present disclosure pertains that various substitutions, modifications, and changes are possible within the scope not departing from the technical spirit of the present disclosure.

INDUSTRIAL APPLICABILITY

[0056] The present disclosure relates to a boat having a rolling reduction function that reduces rolling and makes it very easy to get on the boat in water. By filling a rolling reduction tube, which surrounds a boat main body, with water during sailing of the boat, the overall weight of the boat can be increased, and the center of mass can be moved downward and distributed.
