Interesting. The southern cross was used for navigation in the southern hemisphere.Southern Cross was written as he sailed south from Hawaii to Tahiti on his own sail boat. It was an old, traditional gaff rigged Baltic trader, not some fancy rich man's yacht. Long before GPS, chartplotters and AIS, too. Perhaps that might give the song more meaning for you.
It has been used in many logos, including the 1st Marine Division at Guadacanal
