<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">platform for disembarking</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for landing stage that I've seen before include "Platform for disembarking" , "berth" , "on quayside - with 42a" , "where cargos unloaded" , "Place to board boat" .)
