Boating is often an activity associated with the rich and famous, and at the same time many wealthy people are also taking an interest in submarines. Exomos, a submarine manufacturer has combined "yachting" with a submarine design and has created a line of luxury yachts that are also able to submerge and act as submarines. Depths for these hybrid subs vary but the one show above, the Proteus can dive to 60 feet. The Proteus can also carry up to 24 people. 16 divers can sit on the outside deck of the boat as it submerges and 8 people can watch from inside. These new line of sub-yachts are sure to make Saturdays exciting for some lucky millionaires. More into at the Exomos website, found via Gizmodo
