Submersible superyachts for billionaires: This Austrian company wants to build them

There’s been a trend in recent years for billionaire basements – subterranean extensions to the homes of the rich and famous, where they can bunker down and live large.

Now an Austrian company wants to extend this opportunity for deep-dive delights to the world of superyachts, by building customized private submersibles that can descend 250 meters (820 feet) beneath the ocean surface and remain submerged for up to four weeks.

Migaloo has revealed its ambitious plans for what it claims will be the “world’s one and only private submersible superyacht,” offering “a not-yet-existing alternative to large privately owned surface vessels.”

Billionaires’ playground

This submarine, named M5, would measure 165.8 meters in length and 23 meters across at its widest point, with a range of around 15,000 kilometers and a speed of up to 20 knots when surfaced (or 12 knots when underwater). However, says Migaloo, “The wished dimensions of the submarine-yacht hybrid, the exterior styling and the interior design are up to the owners’ preferences.”
