Stature of hospital rowing crew (6)
I believe the answer is:
height
'stature' is the definition.
(I've seen this before)
'hospital rowing crew' is the wordplay.
'hospital' becomes 'h'.
'rowing crew' becomes 'eight' (I've seen this before).
'h'+'eight'='HEIGHT'
'of' acts as a link.
(Other definitions for height that I've seen before include "Altitude or elevation" , "Measure it from top to bottom" , "Rising ground; extreme example" , "Distance above ground or sea" , "summit" .)
