CONSTITUTION: A first tube(1000) floats on water with filling air inside thereof. A second tube(2000) and a third tube(3000) float on water with air filled therein. A fourth tube(4000) floats connected with the third tube. A first footplate(5000) connects the first tube and the third tube after separating with a specific interval while a second footplate(6000) connects the second and the fourth tubes. By the first footplate, the first and third tubes are fixed and the second tube and the fourth tube are fixed by the second footplate. Then a boat is made by the first, second, third and fourth tubes covered thereupon. Likewise, a user uses a boat in assembly type that boat movement is convenient. In case at least one of tubes has a hole, other tubes retain air for a user not to be drowned to prevent an accident.
