"In all honesty there's enough information (in the protocol) to allow you to start getting a budget together," Slingsby told mysailing.com.au.
"I'm pretty sure it (the AC75) will be foiling. Maybe not upwind but certainly downwind in certain wind strengths. We know roughly the size of the crews needed, but that's not our problem."
With Australians well represented across the crews at this year's event in Bermuda, including three of the skippers - Team NZ's Glenn Ashby, Jimmy Spithill of Oracle Team USA and Artemis' Nathan Outteridge - there is a strong belief Australia could be a force to be reckoned with if they were to re-enter the America's Cup.
There hasn't been an Australian syndicate in the America's Cup since the last event in Auckland in 2003, but with Team NZ moving to tighten the nationality rules for the crew for the 36th America's Cup, there is a sense the time is right for Australia to get back in the game.
"Here in Australia we've got enough interest, we've got the sailors, the boat builders, the shore crew, the managers. It's just a question of rasing the money and getting the right team together," said Slingsby.
"Now's the time to do it. I've got a couple more (Cup campaigns) left in me. I'd like my legacy to be an Australian team that's campaigning long after I'm gone."
The prospect of an Australian challenge could prove tempting for Ashby, who told the Herald last week he is yet to decide whether he will commit to Team NZ's 2021 defence.
