Angry about sails getting wet (8)
I believe the answer is:
irrigate
'wet' is the definition.
(irrigating is a kind of wetting)
'angry about sails' is the wordplay.
'angry' becomes 'irate' ('irate' can be similar in meaning to 'angry').
'about' is an insertion indicator.
'sails' becomes 'rig' (I've seen this in other clues).
'irate' going around 'rig' is 'IRRIGATE'.
'getting' acts as a link.
(Other definitions for irrigate that I've seen before include "Supply land with water to make fertile" , "Bring water to (crops)" , "Supply water to land to help growth" , "Provide (agricultural land) with water" , "Provide water artificially" .)
