[0014] 1. The present invention provides a boarding floating platform device comprising a housing, a connecting assembly, and a suction cup. One side of the housing is connected to the hull via a lifting assembly. An adaptive assembly is provided inside the housing, comprising an intermediate shaft, a first intermediate support plate, a second intermediate support plate, a baffle, a first movable plate, and an adjusting spring.
