Abstract

PURPOSE: To maintain high-speed sailability and lateral stability by providing stepped portions which locate above plowing chines in the area ranging from the bow to the central portion of the boat hull, merging in the chines at the stern, and locate below the draft line when the boat is at still.
CONSTITUTION: A boat body 1 provied with a cabin 2 is formed on its both sides with plowing chines 2 stretching longitudinally. The chines 8 locate below the static draft line 6 in the area raning from the central postion of the body 1 to the stern portion. Above the chines 8 are formed stepped portions 9 which approach the chine 8 as the stern is approached, and finally merge in the chines 8. During sailing, the chines 8 plow water in the directions of arrows 10; the stepped portions 9 do not offer resistance against sailing because they are above the water surface 11. When the boat is still or sailing at low speed, the chines 8 and the portions 9 are below the water surface 11, and act to cancel the bow-raising tendency during sailing. When the boat is inclined laterally, the portions 9 reach the water surface 11 to increse the width of the boat, maintaining lateral stability. Thus, inter-chine distance is reduced and high-speed performance is improved.
