Sailors in team synch manoeuvring (9)

I believe the answer is:

yachtsmen

'sailors' is the definition.
(yachtsman is a kind of sailor)

'team synch manoeuvring' is the wordplay.
'manoeuvring' is an anagram indicator.
'team'+'synch'='teamsynch'
'teamsynch' with letters rearranged gives 'YACHTSMEN'.

'in' is the link.

(Another definition for yachtsmen that I've seen is " Sailors".)

I've seen this clue in The Telegraph.
