PROBLEM TO BE SOLVED: To prevent bow waves by providing a recessed part 24 on the upper side of a bulb bow 2 equipped with a horizontal plate 23 in the bow lower side, to partition the frame breadth into three portions to form ballast tanks, and to improve a heel adjustment function without using the central partition as a ballast tank. SOLUTION: Within a hull 1, the frame breadth is partitioned into three portions by vertical partition walls 63, 64. The partition positioned at the center is a space part 10, and right and left partitions are used for the ballast tanks 75. The recessed part 24 recessed to the stern direction and extended to the frame breadth direction of the hull 1 is provided in the position of a load line above the bulb bow 22 and on the bow lower side, and the horizontal plate 23 is provided in the bulb bow 22.
