Channel surfer's original characteristic (6)

I believe the answer is:

strait

'channel' is the definition.
(strait is a kind of channel)

'surfer's original characteristic' is the wordplay.
'original' suggests taking the first letters.
'characteristic' becomes 'trait' (I've seen this before).
The first letter of 'surfers' is 's'.
's'+'trait'='STRAIT'

(Other definitions for strait that I've seen before include "Narrow sea passage" , "Narrow waterway" , "Sound" , "watery scene?" , "of Gibraltar, for example" .)

I've seen this clue in The Telegraph.
