Eccentric wears kit to skim the surface (5-3)
I believe the answer is:
water-ski
'to skim the surface' is the definition.
I can't tell whether this definition defines the answer.
'eccentric wears kit' is the wordplay.
'eccentric' indicates an anagram.
'wears'+'kit'='wearskit'
'wearskit' with letters rearranged gives 'WATER-SKI'.
Can you help me to learn more?
(Other definitions for water-ski that I've seen before include "Travel behind boat on boards" , "Be towed behind a speedboat" , "Glide over a lake or sea" , "Tweak sir (anag)" , "Get towed behind a motorboat" .)
