Made by Migaloo in Graz, Austria, the Migaloo Private Submersible Yacht is pretty outstanding.
This submarine yacht is 377-feet long and features a helipad, 8 VIP suites, swimming pool, jacuzzi, movie theater, library, private terraces and more.
Yes, the yacht can transform into a submarine! All you have to do is press a button and it becomes a submarine which can take you down to a depth of almost 800-feet!
Cost is confidential. A similar vessel costs around $2 billion dollars though.
