Claims

[Scope of utility model registration request]

An upper hull located above the water surface, a pair of submerged bodies located below the water surface below the upper hull, and struts provided in pairs to connect the same pair of submerged bodies to the upper hull, respectively. , each of the above-mentioned supports is formed so that its width is approximately constant between the minimum draft and the maximum draft, and the spacing between the center lines of the paired supports is formed such that the width thereof is approximately constant between the minimum draft and the maximum draft. At least a portion of each of the pillars is inclined so as to spread upwardly between the two, and a posture control fin is provided on the outside of each of the pair of submerged bodies so as not to protrude from the side edge of the upper hull. A semi-submerged catamaran characterized by being equipped with a
