Migaloo Private Luxury Submarine - Meet Migaloo, the world’s most expensive private luxury submarine. This submarine is absolutely huge, measuring over 377 feet long by 36 feet wide, the submarine is anything but small. It bears the appearance of a traditional submarine in most aspects but the tower is custom designed in order to house a staircase and elevator shaft. The enormous space of the aft deck includes lounge areas, sun beds, a bar, an 8 by 3 meter-pool as well as a heli-pad. When Migaloo is submerged, all furniture is stored underneath the granite decking and the pool bottom rises to form a flush deck. Thanks for watching.
