<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">rescue craft</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that lifeboat is a type of sea rescue vessel)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for lifeboat that I've seen before include "It's used to rescue people at sea" , "I bet loaf on maritime rescue vessel" , "Sea rescue craft" , "It carries out rescues at sea, and is carried aboard large ships" , "Rescuer" .)
