    StandoutExceptional marine biodiversity

    Milne Bay, a place synonymous with WWII wrecks, holds a few deeper secrets, and the American PT Cruisers are certainly among them. Sunk in 1942 near Tufi, these two patrol torpedo boats offer a truly unique, albeit challenging, dive. We’re talking about very complete wrecks, not just scattered fragments, which makes them incredibly evocative. This is a decompression dive for seasoned wreck enthusiasts, divers who understand the nuances of planning and execution when conditions align. If you've got the training and the urge to connect with history in a very profound way, these PT boats are an incredible expedition.
