See JP-A-60-12182). This type of boat 1 (see FIG. 4) is integrally formed by blow-molding plastic and is a hollow body having a double wall structure as a whole, and the inner and outer walls of the boat bottom 2 are welded at various places of the double wall. The welded portion 3) is formed, and in some cases, a vertical rib is formed on the bottom surface of the outer wall to increase rigidity.

部のみに限られる。On the other hand, in the side part 4, the distance between the double walls is widened in order to secure the buoyancy and the restoring force, and it is difficult to increase the rigidity by welding the inner and outer walls. Therefore, in some cases, the concave ribs 5 in the vertical direction are formed on the outer wall to increase the rigidity. However, water resistance near the water surface is limited to only the upper half on the side of the ship because of water resistance.

アップにつながる。In the boat 1 integrally formed by blow molding, the outer wall of the side part 4 has a relatively small thickness. In other words, in blow molding, a plastic cylindrical parison is sandwiched in oppositely arranged molds, and air is blown into the parison to expand the parison and conform to the inner shape of the mold to obtain a predetermined shape. This is because the degree of extension of the parison differs depending on the location, and in the molded body having a shape like the boat 1, the extension degree of the outer wall A of the side part 4, particularly the location indicated by A 'increases. This tendency becomes stronger as the ratio h / w between the height h and the width w of the boat 1 increases. As described above, the lower half of the side wall A cannot be rigidly increased by the ribs. Further, since the lower half of the outer wall A is most likely to hit a quay or a rock, dents and holes are easily generated by the impact. . In order to increase the strength by increasing the thickness of this portion, it is necessary to increase the thickness of the entire hull, which leads to an increase in material cost and hull weight.

の床面積を大きくとることができなかった。The inner and outer walls of the side portion 4 of the boat 1 are inclined outward over the entire height h of the boat 1. This is because when the blow-molded boat 1 is extracted from the mold, a draft gradient is required over the entire height h.
The width w1 of the bottom 2 of the boat 1 is small for the large width w and the usable floor area is small. For example, in the case where the boat is transported with the bottom of the boat facing upward and the top of the side part 4 fixed, the size of the lateral width w of the boat 1 is limited by the mounting width of the roof of the automobile, and accordingly, the size of the boat 1
Floor space could not be increased.

(Width Y, height H 1 ) and upper hull 13 (width Y, height H 2 ) constituting the upper part of the hull are assembled by bolts 14 or the like (see FIG. 4), and the lower hull 12 and the upper hull are assembled. Numeral 13 is a hollow body having a double wall structure by blow molding. And the upper hull 13 is the lower hull 12

Then, the top portion 16 of the upper hull 13 projects inward, and a mounting seat for the roof of the automobile is formed here. Looking at the internal structure, at the joint between the upper and lower hulls 12 and 13, two plates a and b are connected to the inner and outer walls around substantially the entire hull (a part of the side, bow, and stern). ing. Ship bottom 11
Here, the inner and outer walls are welded in places as in the conventional example.

を落とさずに３０％程度の軽量化が可能である）。In the boat 10, the ratio H 1 / Y or H 2 / Y of the height and width of the lower hull 12 and the upper hull 13 can be set to be considerably smaller than the ratio h / w of the conventional boat 1. Therefore, the degree of stretching of each part by the blow molding is relatively uniform, the variation in the wall thickness is reduced over the entire inner and outer walls, and the outer wall on the side of the side is prevented from being particularly thinned. In addition, the inner and outer walls of the outermost part of the side of the pier are connected by two plates a and b, which are reinforced so that they are resistant to impacts. It is prevented from occurring. Since the two plates a and b connect the inner and outer walls around substantially the entire circumference of the hull, the rigidity of the hull as a structural body becomes extremely high, and the average thickness of the inner and outer walls is reduced accordingly. It is possible to reduce the weight of the hull (if the external dimensions are the same as the conventional example, it is possible to reduce the weight by about 30% without reducing the rigidity).

And since the slope of the upper hull 13 is reversed, as compared with the conventional example, in spite of the magnitude of the lateral width Y of the hull can be made larger width Y 1 of the ship bottom portion of 11, a large floor area boat Can be obtained. In addition, this boat has
Overhang 6 inwardly, so forming a mounting seat for an automobile roof thereto, it is carried put a boat with a wide vessel bottom portion width Y 1 and floor space in spite of the mounting width of the roof of an automobile in an automobile it can. For example, if the boat has the same mounting width, it is possible to obtain a boat having twice the floor area with 1.2 times the weight of the conventional example.

Then, it may be assembled at the time of use. The upper hull is not limited to the C-shape, but may be an O-shape that completely covers the stern. Further, the inclination of the upper hull can be set arbitrarily without being limited to the above embodiment, and the overhanging shape of the top can be set arbitrarily including the presence or absence thereof. Further, the assembling surface of the lower hull and the upper hull may be formed as one plane as in the embodiment, but one or more convex portions are formed on one side of the assembling surface, and the other side is formed. And a concave portion corresponding thereto can be formed, and both can be fitted together.

とができる。According to the present invention, the thickness of the outer wall of the side of the ship is prevented from being reduced, and the intermediate region (the surface for mounting the upper and lower hulls) of the side of the ship is strengthened. It is possible to prevent the occurrence of a hole, and it is not necessary to increase the material cost and the hull weight. And, on the mounting surface of the upper and lower hulls, since the two boards surrounding the entire circumference or almost the entire circumference of the hull are connected to the inner and outer walls, the rigidity of the hull structure becomes extremely high, Accordingly, the average thickness of the inner and outer walls can be reduced, and the weight of the hull can be reduced. Further, since the inclination of the side of the lower hull and the inclination of the side of the upper hull can be set separately, a boat having a large floor area at the bottom of the boat can be obtained for the width. Further, when the top of the upper hull projects toward the cabin side, a boat having a large floor area for the installation width can be mounted on the roof of a car and conveyed.
