Princess Cruise Ship Horn Battle

Diamond Princess Versus Sun Princess

The Diamond Princess and Sun Princess cruise ships had a horn battle caught on video in Melbourne, Australia.  While it is hard tell where the sounds are coming from in the video, you can plainly see the vibrations caused by the horn on the ship that the video is being filmed from.  About halfway through, the ships start to sound like they are playing a toon with their horns!

Listen to the horn battle now!
