Abstract

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. The present disclosure has the following advantageous effects. That is, according to the present disclosure, by filling a rolling reduction tube, which surrounds a boat main body, with water, there are advantages that the overall weight of the boat is increased, and the center of mass is moved downward and distributed, thus making it easy to get on the boat even in water, and the degree to which the boat tilts or rolls due to external factors such as a strong wind, a wave, and a change in the position of a passenger is reduced and a restoring force of the boat is increased, thus making it possible to more safely sail the boat.

Description

TECHNICAL FIELD 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, and more particularly, to a rolling reduction boat having a structure that allows a rolling reduction tube, which surrounds a boat main body, to be filled with water during sailing of the boat. BACKGROUND ART Generally, small and medium-sized boats such as yachts, fishing boats, and coastal fishing boats have advantages that transportation and storage are convenient and costs are inexpensive due to their small sizes. However, there are disadvantages that it is actually impossible to get on the boat again after falling into the water, the boat may tilt or roll due to external factors such as a strong wind, a wave, and a change in the position of a passenger, and in severe cases, the risk of capsizing is high. In order to address such problems, techniques and methods for attaching an auxiliary device for adding buoyancy to the hull have been developed, but there are problems that tasks of assembling and disassembling the auxiliary device are complicated, for example, the auxiliary device should be assembled or installed in advance on land before sailing and should be disassembled and separately stored when not sailing, and the structure is not satisfactory. Accordingly, the present applicant has conducted research on and developed a rolling reduction boat configured to allow a rolling reduction tube to be filled with water at any time, in water before getting on the boat and even after getting on the boat, thus preventing tilting, rolling, and capsizing of the boat. DISCLOSURE Technical Problem The present disclosure is directed to providing a rolling reduction boat configured to allow a rolling reduction tube, formed to surround a boat main body, to be filled with water during sailing of the boat, thus making it easy to get on the boat in water and preventing tilting, rolling, and capsizing of the boat. Technical Solution The present disclosure proposes a rolling reduction boat including: a boat main body (100); rolling reduction tubes (200, 200′) formed to surround a side portion of the boat main body (100); a tube connection member (300) coupled to communicate with front end openings of the rolling reduction tubes (200, 200′) and having a water injection hole (310), through which water is injected, formed to pass through an upper side; a water injection member (400) formed at a lower portion of a front side of the boat main body (100) to inject water into the water injection hole (310), having a plate shape, extending forward, having a bendable material, and configured to submerge in water when the boat main body (100) is disposed on water; a coupling protrusion (500) formed on an upper portion of the front side of the boat main body (100) and configured to protrude forward; an extension member (600) 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; a pitching prevention member (700) 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; and a rope ladder (800) formed at a rear side of the boat main body (100), wherein the rolling reduction tubes (200, 200′) include opening maintenance members (210, 210′) formed to surround the front end openings of the rolling reduction tubes (200, 200′) to maintain an open state of the rolling reduction tubes (200, 200′), the tube connection member (300) includes 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, 200′), and the water injection member (400) includes 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. Advantageous Effects According to the present disclosure, by filling a rolling reduction tube, which surrounds a boat main body, with water during sailing of the boat, there are advantages that the overall weight of the boat is increased, and the center of mass is moved downward and distributed, thus making it easy to get on the boat even after falling into the water, and the degree to which the boat tilts or rolls due to external factors such as a strong wind, a wave, and a change in the position of a passenger is reduced and a restoring force of the boat is increased, thus making it possible to safely get on the boat again even after falling into the water and sail the boat.
