Regularly encountering waves restyled as a fringe (9)
I believe the answer is:
'regularly encountering waves' is the definition.
(travelling the seas)
'restyled as a fringe' is the wordplay.
'restyled' is an anagram indicator.
'asafringe' anagrammed gives 'SEAFARING'.
(Other definitions for seafaring that I've seen before include "ocean travel" , "Travelling the ocean" , "So Jack's likely to be" , "Just like Jack" , "Sailor's way of life" .)
