'engage in splashy sport' is the definition.
I can't tell whether this defines the answer.

'it wreaks havoc' is the wordplay.
'havoc' indicates anagramming the letters (I've seen this in other clues).
'it'+'wreaks'='itwreaks'
'itwreaks' is an anagram of 'WATER-SKI'.

Can you help me to learn more?
