The 'miniaturization' is reflected in that the expansion size of the floating platform after inflation is about 1500mm multiplied by 1100mm, the sitting area is about 0.95m 2, and the rated load is 2. The invention provides a sinking ship bottom with high wave resistance, which is deeper, and when a user sits on the ship bottom, the depth of the ship bottom is lower than that of a lower pontoon, so that the ship body is more difficult to topple, the stability of the ship is improved, and the ship can resist five-level sea conditions, thereby better providing a life-saving platform for people in distress.
