Record of a voyage (3)
I believe the answer is:
log
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">record of a voyage</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 log that I've seen before include "Official record; cut part of tree trunk" , "Nautical record in timber?" , "Diary kept by ship's captain" , "number in maths class?" , "Register" .)
