How a table moves about in seagoing vessel (9)
I believe the answer is:
whaleboat
'seagoing vessel' is the definition.
'whaleboat' can be an answer for 'vessel' (whaleboat is a kind of vessel). I am unsure of the 'seagoing' bit.
'how a table moves about' is the wordplay.
'moves about' indicates anagramming the letters.
'how'+'a'+'table'='howatable'
'howatable' with letters rearranged gives 'WHALEBOAT'.
'in' is the link.
Can you help me to learn more?
(Other definitions for whaleboat that I've seen before include "sailing vessel" , "Harpooner's vessel" .)
