Boak was voted in by his teammates once again, with 22-year-old Ollie Wines appointed to the position of vice-captain for the first time.
“To be given the job of leading this group of players is a huge responsibility, but something I’m ready for once again in 2017,” Boak said.
“Captaining Port Adelaide is an honour, as much now as when I first was given the job for the 2013 season.
“Ollie will be a great vice-captain and he has developed tremendously since debuting in 2013, and having Hamish, Brad, TJ and Jacko in the group provides some strong, senior experience for the rest of our group. We’re very excited for next year.”
Boak will become the club’s longest serving captain, with the 28-year-old set to overtake Warren Tredrea during the 2017 season.
