With work commitments and the arrival of baby twins keeping regular skipper Lee Knapton landlocked for much of the summer, Gerard Smith, Bryce Edwards, Kurt Hansen, Chris Nicholson, Dave O'Connor and Nathan Wilmot have all taken turns on steering duties.
"It's been great all those guys have been able to help us out but it does make things difficult when you are constantly swapping skippers," Mackie said.
"It’s probably no surprise our season has been pretty up and down."
It was Wilmot's turn to play the role of stand-in skipper last Saturday and it proved a seamless handover.
A dominant win in Manly's fifth club championship heat of the summer was a reminder of what Brydens – a multiple state and national champion – is capable of when all is in tune.
Wilmot opened up a good lead up on the initial windward run and was first around the mark, leaving club championships aspirants Fire Stopping (Joe Turner) and Fluid Building (Clint Bowen) to play catch up.
Brydens' lead was never really threatened as they pulled away for a comfortable 2min:15sec victory.
Fire Stopping was second with Fluid close behind in third.
