Just a short video of sailing from the Sydney White Bay Cruise terminal on the 17th December 2022 on the Pacific Adventure, Which is the largest ship to date to go under the Sydney harbour bridge at 109,000 gross registered tonnes with just 2 metres clearance at low tide before it hits the deck of the bridge.
In order to go under the bridge it had to have its funnels shortend, So if you look at the pacific adventure today compared to its old golden Princess days, You can see what they did to the funnel to ensure it fit under the 90 year old Sydney harbour bridge. Allowing it to use White bay pretty much exclusively year round rather then fight for the overseas passenger terminal at circular quay.
