Boater say by church finds shade (5)
I believe the answer is:
hatch
'shade' is the definition.
(I've seen this before)
'boater say by church' is the wordplay.
'boater say' becomes 'hat' (boater is a type of hat).
'by' says to put letters next to each other.
'church' becomes 'ch' (common abbreviation).
'hat'+'ch'='HATCH'
'finds' is the link.
(Other definitions for hatch that I've seen before include "Emerge from shell" , "Incubate - plan" , "Draw fine lines" , "Incubate - opening" , "Of young bird or fish, emerge from egg" .)
