Hansa Bay is a popular diving spot past Bogia, where the wreckage of 35 Japanese freighters and US aircraft lie in a shallow harbour. The upper deck of the 6000-ton Shishi Maru lies in just 6m of water, two anti-aircraft guns on the bow point upwards and brass shell castings litter the deck. Two fire engines are sitting in the hold, just before the bridge, where they were waiting to be unloaded.
