$3.5 Million Submarine-Powerboat Marion HSPD up for grabs

You might have all the superyachts in the world, but not a submarine-powerboat hybrid. If you don’t, you can now actually buy one for $3.5 million. Crafted by Marion HSPD, the powerboat is a 31-ft. surface-cruiser spotting a closed cabin. This Hyper-Sub can hit a maximum surface speed of 40 knots along with a maximum surface range of 500 miles. If you prefer the dive mode instead, the Hyper-Sub can go deep down up to 250 feet. The boat also gives umbilical SCUBA support.
