Rowing boat club? I remember some of that (6)
I believe the answer is:
bireme
'rowing boat' is the definition.
(type of rowing ship)
'club? i remember some of that' is the wordplay.
'some of that' indicates a hidden word.
'BIREME' can be found hidden inside 'club i remember'.
(Other definitions for bireme that I've seen before include "Ancient rowed warship" , "rowing boat" , "Old craft with two banks of oars" , "Type of ancient galley" , "with two tiers" .)
