<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">from a ship into the water</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 overboard that I've seen before include "in need of a life jacket" , "(Fall) into the sea" , "Man . . . . . . . . . - launch the lifeboat!" , "Off boat into water" , "excess" .)
