With the recent capsize and sinking of the mega yacht Yogi in the Aegean Sea off Greece in moderate gale conditions, there has been a lot of chatter about the causes, and several SetSailors have asked us our thoughts.
We have not had much time to devote to this incident, but from the photos and scuttlebutt it seems the 60 meter Yogi was disabled, sitting beam to the seas, and became the victim of synchronous rolling which induced the capsize.
However, this is idle speculation without more facts. Once we are in possession of something more concrete, we’ll tell you what we think. Following are a few photos of the incident, along with a link to our earlier article about stability and capsize risks for yachts.
According to the website Dockwalk.com, the vessel suffered “mechanical difficulties” in “gale force winds”.
Another aerial photo of Yogi. From this perspective, you can tell that the seas were probably not running any larger than 10-15 feet/3-5m at their maximum, and most likely less.
If you Google yacht Yogi you will find lots of speculation, video, and information on the vessel. Take a look at her waterline length, beam, and draft.
LOA 60.2 metres
LWL 54.8 metres
Beam 9.4 metres
Draught 3.3 metres
She is a high volume configuration in mega-yacht terms, but nothing like the norm for many smaller motor yachts these days. It is precisely this combination of factors which increases capsize risk in vessels that do not have inherent self-righting capability.
