Generally, a boat is a vehicle that can be operated by a screw device driven by a drive motor on a water surface. Such a boat is usually used to carry a person or a cargo in a watercraft, It is impossible to ascend to the ground or operate on the ground without the means or apparatus of

Therefore, conventional boats have to be moved to a separate pier or a waterfront near the waterfront where they can berth, and then the passenger or cargo of the boat must be lowered.

In addition, in order to keep the boat moving overland, it is necessary to carry it on a special vehicle such as a separate trailer and move it to the owner's house, or to pay for the boat at a separate expense, There is a problem that durability and utility of the boat deteriorate because a lot of cost is spent in management.

Therefore, conventionally, in order to solve the above-mentioned problem, many amphibious boats which can be operated on land have been proposed.

Among them, 'prefabricated amphibious hovercraft' of Registration Utility Model No. 20-0398990 and 'amphibious boat' of Laid-Open Patent No. 10-2012-0013753 are known, and the construction of these is schematically described as follows .

The 'assembled amphibious hovercraft' includes a skirt body having a tube accommodating portion formed with a plurality of openings on a bottom surface thereof, an air injection bag integrally formed at an upper portion thereof for receiving strong force of air from the engine, A foldable body supporting device that is folded and joined to an upper surface of the skirt body, an engine driving device provided behind the foldable body supporting device, a chair supporting and adjusting device coupled to the center of the foldable body supporting device, A chair coupled to the chair support and adjustment device, and a steering lever for the driver to control the operation.

However, since the 'prefabricated amphibian Hobo Craft' is a part of the air output from the engine, it may flow into the air inflating bag and the skirt body and move up to a predetermined height from the water surface or the ground. However, There is a problem in that it is difficult to fall off and change direction. Further, when the air injection bag and the skirt body are damaged during storage or operation, there is a problem that the operation is difficult and the safety accident occurs.
