The invention relates to shipbuilding. A bottom of planing boat is made in the form of a tunnel trimaran, the construction consists of central and two lateral longitudinal gliding skis made with a concave surface. The central longitudinal glading ski is made with the concave surface that tapers to the fore, being bent down to the stern as regards to the lateral side of longitudinal skis and located above the lateral longitudinal skis. On either side of the lateral longitudinal skis the longitudinal steps are made. Concavity of the planing surface of longitudinal side skis in the stern is made with a smooth decrease at increasing of the planing angle of concave surface. The technical result is the improved speed and hydrodynamic characteristics of the ship.
