Rotating bobbins for light boats (6)
I believe the answer is:
sloops
'light boats' is the definition.
'sloops' can be an answer for 'boats' (I've seen this before). I'm not certain of the 'light' bit.
'rotating bobbins' is the wordplay.
'rotating' says the letters should be written in reverse.
'bobbins' becomes 'spools' ('spool' can be a synonym of 'bobbin').
'spools' in reverse letter order is 'SLOOPS'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for sloops that I've seen before include "Boats" , "Sailing vessels rigged fore and aft" , "sailing vessels follow" , "ships" .)
