Ryder is entertaining a move away from the Bombers despite being only two years into a four-year contract, and reportedly met Brisbane Lions coach Justin Leppitsch on Tuesday.
But Port Adelaide is believed to be well positioned to snare Ryder's services, which would satisfy the club's need for another forward/ruckman.
Boak played alongside the athletic big man a number of years ago in Ireland and said he was exactly the character Port wanted.
"Paddy's a fantastic player; I think any club would be pretty lucky to have him," Boak said.
"I was lucky enough to play over in Ireland in [All Australian] under-17s with him and he's a fantastic person and certainly a fantastic player.
"It'd certainly add a fair bit to our team … just the type of player he is. I think he could add a lot all over the ground for us.
"It'd help 'Lobbes' (Matthew Lobbe) out a fair bit; we've still got 'Reddo' (Jarrad Redden) who's coming back from a knee injury – so we've got a bit of stock there – [but] to add another one to the forward line would be fantastic."
However, Boak said his immediate attention was focused on Saturday's preliminary final against Hawthorn.
The Power will enter the game as underdogs, but the captain said his side had proven its ability to match the Hawks.
"We know it's going to be a big challenge for us, we know they're the reigning premiers – they're a fantastic side – but in saying that we've got complete faith in our game style as well.
"I think we showed it this year when we played some big games, including Hawthorn. They had a few out, but certainly if we can bring our best footy then we'll be right in the game."
Boak and teammate Robbie Gray gained All Australian selection on Tuesday night, Boak's second cap in as many years.
He said that while the honour was the type of reward rarely appreciated until retirement, Gray's selection confirmed him as one of the game's very best.
Gray debut in the All Australian side followed his AFL Coaches Association Player of the Year crown, and he is tipped to poll well at next week's Brownlow Medal.
"He's showed it this year that he's one of the best in the comp and his consistency all year is what's been a real highlight," Boak said.
"For him to come back from that horrific knee injury … we all knew he had the talent, and what he's learnt and what he's been able to achieve now has put him right up there with the best in the competition."
