Some billionaire just had a really bad day.

The Proteksan-Turquoise designed and built superyacht, YOGI, sank this morning off the coast Skyros, a small Greek island located in Aegean Sea.

The 60.2m superyacht, which has only been up for charter since the summer of 2011, was reportedly in the area for “minor warranty” work when it suffered a mechanical failure, began to list, and eventually sank.  Luckily the Hellenic Coast Guard was on scene with a Super Puma helicopter and was able to get everyone off safely.

YOGI featured accommodation for 12 guests in 6 cabins (5 double, 1 twin), and a large main deck master suite with lounge/day area, office area, dressing room and his and hers en suite bathrooms.  Amongst her many features were a large jacuzzi on the sun deck, a temperature regulated swimming pool with a skylight to the beach club below on the aft deck, two beach clubs, a massage room, a multimedia play lounge and a sun deck Teppanyaki bar.

The superyacht was available for charter through the superyacht charter company Burgess with rates of $469,000 to$497,000 per week.
