'part in the regatta?' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'a couple of teachers' is the wordplay.
'a couple of' becomes 'two' (a couple is two things).
'teachers' becomes 'masters' (master can mean a school teacher).
'two'+'masters'='TWOMASTERS'

'taking' is the link.
