I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">seaboard</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for coast that I've seen before include "Move easily without power" , "Where the land and sea meet" , "Run without power" , "(Of car) move without power" , "Land next to the sea" .)
