Model racing boat docked point (6)
I believe the answer is:
sculpt
'model' is the definition.
(thesaurus)
'racing boat docked point' is the wordplay.
'racing boat' becomes 'scull' (scull is a kind of racing boat).
'docked' means to remove the last letter (to dock can mean to remove the tail of an animal).
'point' becomes 'pt'.
'scull' with its final letter taken away is 'scul'.
'scul'+'pt'='SCULPT'
(Other definitions for sculpt that I've seen before include "Oak fruit" , "Carve a shape" , "Create by shaping a material" , "Carve in wood/metal" , "Shape from stone or wood" .)
