<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">small group of ships</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 flotilla that I've seen before include "number of vessels" , "Fleet of small ships" , "set of vessels" , "Fleet of small warships" , "Group of boats or small warships" .)
