Stabilised hull of a monohull motor boat, which is using surfing glide on a water cushion, with a deeply submerged displacement bearing blade, wherein the total width of the hull is of not more than 50% of its length, which in its lower part: - has over its entire length, a descending shape of its bottom surface in the direction bow-to-stern, - wherein, the bow end of the bottom surface is elevated to the distance from the waterline, corresponding to at least 25% of the width of the hull; where there is a high wave-piercing stem located under the bow end of the bottom surface, - wherein, in the front 40% of the length of the hull, the bottom surface has a descending shape, smoothly flowing into the bottom surface of the stern part of the hull, and has the angle of descent of at least 5 degrees, in relation to the waterline at zero speed, - wherein, in the rear 60% of the length of the hull, the bottom surface has a descending shape, and has the angle of descent in relation to the waterline at zero speed, of not more than 5 degrees, wherein it has a nearly flat shape in its cross section and is submerged by 70% or more of its length below the waterline as counting from the stern, where the submerged part becomes the "surfing surface", which is gliding during the boat's run, on the water cushion, and carrying no more than 70% of the boat's fully loaded weight, - wherein, the hull is made with a longitudinally positioned located underneath its bottom surface, symmetrical in relation to the boats' centerline and commensurate with its length, vertically oriented deeply submerged displacement bearing blade of narrow shape and of low wave/hydrodynamic resistance, - wherein, the ratio of the length to the width of the bearing blade is at least 20 times, with the displacement of the bearing blade corresponding to 30-50% of the boat's fully loaded weight, and with the height (excluding the stem) of not less than 20% of the maximum width of the hull, wherein ensuring a deep submersion of the bottom edge of the bearing blade in relation to the waterline, - wherein, the bearing blade is made with the wave-piercing lines, a high wave-piercing stem, which by its height is reaching the bow end of the bottom surface of the hull, with the sharp rear and front lines, and smooth lines in the middle, - wherein, the bearing blade, over its entire length, has a triangular shape in its cross section, with the most acute angle at its bottom; and the maximum width of the bearing blade is located within 40-60% of its length, which determines the centre of the displacement of the bearing blade within 40-60% of its length, in its upper third. - has over its entire length, a descending shape of its bottom surface in the direction bow-to-stern, - wherein, the bow end of the bottom surface is elevated to the distance from the waterline, corresponding to at least 25% of the width of the hull; where there is a high wave-piercing stem located under the bow end of the bottom surface, - wherein, in the front 40% of the length of the hull, the bottom surface has a descending shape, smoothly flowing into the bottom surface of the stern part of the hull, and has the angle of descent of at least 5 degrees, in relation to the waterline at zero speed, - wherein, in the rear 60% of the length of the hull, the bottom surface has a descending shape, and has the angle of descent in relation to the waterline at zero speed, of not more than 5 degrees, wherein it has a nearly flat shape in its cross section and is submerged by 70% or more of its length below the waterline as counting from the stern, where the submerged part becomes the "surfing surface", which is gliding during the boat's run, on the water cushion, and carrying no more than 70% of the boat's fully loaded weight, - wherein, the hull is made with a longitudinally positioned located underneath its bottom surface, symmetrical in relation to the boats' centerline and commensurate with its length, vertically oriented deeply submerged displacement bearing blade of narrow shape and of low wave/hydrodynamic resistance, - wherein, the ratio of the length to the width of the bearing blade is at least 20 times, with the displacement of the bearing blade corresponding to 30-50% of the boat's fully loaded weight, and with the height (excluding the stem) of not less than 20% of the maximum width of the hull, wherein ensuring a deep submersion of the bottom edge of the bearing blade in relation to the waterline, - wherein, the bearing blade is made with the wave-piercing lines, a high wave-piercing stem, which by its height is reaching the bow end of the bottom surface of the hull, with the sharp rear and front lines, and smooth lines in the middle, - wherein, the bearing blade, over its entire length, has a triangular shape in its cross section, with the most acute angle at its bottom; and the maximum width of the bearing blade is located within 40-60% of its length, which determines the centre of the displacement of the bearing blade within 40-60% of its length, in its upper third.
