Tied up, as a ship
I believe the answer is:
moored
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">tied up as a ship</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 moored that I've seen before include "Of boat, secured by rope to shore" , "Tied up to berth like ship or boat" , "Secured by rope or cable" , "Of boat, tied up or secured" , "Fastened with a line or anchored" .)
