PURPOSE:To enable to embark and disembark safely, by furnishing a pair of rails both sides at the bottom wall of an embarking section with a watertight door above the draft of the ship side, along which a free sliding ramp is installed, whose lower end is fixed at a tenderboat. CONSTITUTION:A pair of rails 6 are installed parallel with a lateral interval at the bottom wall 5a of an embarking section 5, which has a watertight door 10 and is arranged above the draft of the ship side. In the slit 6a of the rails 6 is inserted a shaft 8 which is furnished at the end of a ramp 7, freely movably by a wheel 9. The tip of the ramp 7 is fixed to a tenderboat 4. Thus, even though the tenderboat heaves on the waves, no difference in level occurs between the ramp 7 and the tenderboat 4, resulting in a safe embarking and disembarking.
