This is the most amazing ship I’ve ever seen...
US Submarines has created this luxury submarine for a client, but he dropped out and now it is for sale... for $78M

“The Phoenix is capable of making trans-Atlantic crossings at 16 knots yet can dive along the route and explore the continental margins of some of the most fascinating waters on earth. And unlike surface yachts, when the water gets rough, the submarine can submerge into a perfectly smooth and quiet environment, continuing on toward its destination, providing a ride unsurpassed in quality ”
