The French Marine Accident Investigation Office, a.k.a. the Bureau d’Enquêtes sur les Évènements de Mer (BEAmer), released its report into the sinking of Yogi this week. In this exclusive interview, Mehmet Karabeyoglu, the CEO of Proteksan Turquoise shares his thoughts on the findings and candidly discusses what has occurred at the yacht yard over the past year.
MegayachtNews.com: Now that the report into the sinking of Yogi has been published, can you explain your feelings?
Mehmet Karabeyoglu: It is difficult to really express precisely how I feel. I am relieved that an independent body of marine experts without, in my opinion, any agenda or vested financial interest in why Yogi sank have published their findings. I cannot say I am happy or sad because the fact remains that a beautiful yacht that encapsulated the physical and intellectual labor of many people sits some 500 meters below the waves; it doesn’t make me happy that the very public sinking is there on YouTube to be viewed time and time again. However, it is clear, as we at the shipyard have always felt and known, that Proteksan Turquoise acted within the law, that the shipyard did everything that was expected of it, and that there was no failings on our part as builders.
Indeed, in April 2012, three Turkish court-appointed experts concluded that Yogi did not sink due to any design or engineering fault or any construction defect, and those court-appointed experts did not avoid the difficult questions.
As to the French report? I am a little frustrated that on some key points, BEAmer’s conclusions and summations of the report are clumsy, as they are illogical and convey misleading impressions. For example, they say that the original inclining test was done without French flag representation, yet the report says that ABS were the flag’s representatives and ABS were present and conducted the tests. How can they then imply that that no one was present at the inclining test?
BEAmer also claim, and on this point we are taking legal advice, that we refused to carry out a new inclining test during the last warranty works, and present as evidence a warranty wish list upon which the merits of an new inclining test are discussed. It is true that on the initial warranty list the owners alleged a listing problem, but the owner’s team removed the item from the warranty list and as far as we know did not report the matter to class. We have no way of knowing if there was a stability problem or if the listing, if any, was caused by some other cause. It was never tested. We did not decline a new inclining test, and we have the emails from the owner’s team to prove it. But BEAmer didn’t think it was important to check their facts. If there was a stability problem, I don’t believe a professional captain would have allowed the matter of a new inclining test to be removed from the warranty list or would have headed off in a force 8. BEAmer unfortunately did not have the good grace to put that allegation to us during the consultation phase. Frankly, I think on both these points, BEAmer have let us, the industry, and themselves down.
MegayachtNews.com: How is it we don’t know about the Turkish courts’ expert inquiry into the sinking?
Mehmet Karabeyoglu: We felt that if we announced the Turkish report before BEAmer had published their findings, it might be received by a sceptical world as being pro-Turkish, given that we had requested the Turkish courts to investigate the sinking. We also didn’t want the Turkish report in any way to taint the official French investigation, but the fact is the yacht sits at the bottom of the ocean, the only real evidence we have is firstly, the video clip on YouTube, secondly what was said by the crew and those witnessing the sinking onboard the surrounding vessels, and finally the certified documentary paper trail of the French flag and the classification society.
What has been troubling over the past year is just how many different versions of the sinking have emanated and how those have evolved and changed. Some of the stories cross over, and others only surfaced several months after the sinking, when logically the story of the sinking should have been consistent.
I have not read all the versions of the sinking, but I think we have the captain’s call to my former partner, Hayati Kamhi, and the yacht’s project manager, Nedim Sukas, wherein one version of the sinking was given which was reported by the press; (2) the testimony of each of the crew to the Hellenic Coastguard; (3) the Rapport de Mer of the captain and the senior officers to the French Ambassador in Athens on 20 February 2012; (4) the interviews with BEAmer; (5) the owner’s insurance claim; (6) the Turkish courts’ expert report. As you can see, there are many possible variations and versions of the truth, and no two versions seem to be identical, and of course now we have the seventh version, that is the BEAmer report, which seems to be chiefly an academic exercise and yet another version of events. I think we need to ask BEAmer just what did they consider and what did they reject as evidence.
Yet, I find it quite interesting that one of the recommendations of the French investigators is that yachts over 500 tons carry the same voyage data recorders that commercial ships carry, in that way you have absolute certainty as to the position of the ship, its speed, what alarms worked and did not work, how the rudder worked and so on. The data on the voyage data recorder is independent, tamper-proof, and verifiable.
MegayachtNews.com: Are you saying that the crew, in giving their testimonies, were not independent, not verifiable, and not tamper-proof?
Mehmet Karabeyoglu: No. Absolutely not. I’m not saying that at all, but the French investigators who ordinarily investigate commercial shipping accidents and having never investigated a yacht sinking of this kind, I think they were unhappy to discover that the only source of evidence for what actually happened on the night the yacht sank was what the crew had said to them several months after the event, and those statements were not capable, at least not easily capable, of being cross-checked, especially when the log book was lost and that yachts do not have either voyage or voice data recorders. But, for some reason it is thrown in as a recommendation, without a logical process to arrive at the recommendation.
MegayachtNews.com: Do you have any knowledge about the insurance claim or what is happening in Greece?
Mehmet Karabeyoglu: As to the insurance claim, I do not want to comment because that is a something for the owners and the insurers to sort out, if it hasn’t already been settled. As to Greece, I understand there is an ongoing criminal investigation.

MegayachtNews.com: The report clearly does not criticize your shipyard or its build practices, but falls short on saying where the fault lies. What are you own personal thoughts on the sinking of the yacht?
Mehmet Karabeyoglu: My own personal thoughts are not really relevant because again I have a vested interested. What I would say is that the vessel was built with state-of-the-art knowledge, and state-of-the-art class and flag rules were applied and certified as applied. She was in class, she was built to the French version of the Large Yacht Code, namely Division 242, and when she originally left the yard on delivery and subsequently when she left the yard after the warranty work, all the work had been signed off, and all of the work requested to be undertaken at the shipyard was completed and signed off by the captain. BEAmer have a copy of the complete warranty list as approved, yet they only published a single page of that list in their report. Everything that needed testing by us was tested. The BEAmer report has made no credible effort to establish the water ingress, even though as photographs show, deck furniture cushions were floating near the sinking yacht. In fact, we delivered to BEAmer a photograph we had taken a few days before the sinking showing all the deck cushions stowed in the beach club…yet there is no acknowledgement of this.
MegayachtNews.com: In retrospect, is there any action you or your shipyard could have taken to prevent the loss of Yogi?
Mehmet Karabeyoglu: In retrospect, I wish we were more forceful in our suggesting to the captain not to sail on that fateful evening. We knew that a storm was coming in, and we suggested that the yacht did not sail until the following day, but the captain was determined to leave, and as the records show, determined to leave and sail into those force 8 winds at high speed, which to this day I cannot understand.
MegayachtNews.com: Did the shipyard receive any cancellation of orders following the sinking?
Mehmet Karabeyoglu: Cancellation of orders? No, but people who were building with us and are still building with us asked us some very searching questions, as did existing owners of our yachts. No one terminated a yacht construction, and no one terminated negotiations with us on the basis of the sinking of Yogi.
MegayachtNews.com: How did the sinking affect the morale of the workforce?
Mehmet Karabeyoglu: As I have said before, each yacht is seen, by us, as our child, and to see a child pass away is an experience a parent never wants to go through, and to say that the morale of the workforce was not affected would be a lie. They were deeply affected. Our craftsmen, shipwrights, and indeed all the designers and support staff are proud people, proud of the work that they do on each individual aspect of a yacht whether it’s seen or unseen, and they are proud of the success that all of their efforts have brought not just to the shipyard but to Turkish yacht building. We cannot live our lives forever mourning, and the yachts that we have subsequently built and are building are benefitting from a re-invigorated pride to show the world that we build some of the best yachts in the world.
MegayachtNews.com: Were you forced to make cutbacks in expenditure or workforce as a direct result of the sinking?
Mehmet Karabeyoglu: Cutbacks? Yes we have made some cutbacks. Is it as a direct result of the sinking or the economic climate? It is difficult to say. It would be easy to blame the sinking of Yogi, but the fact is other yards have also made cutbacks who have not faced our tragedy.
MegayachtNews.com: What do you plan to do to restore the image the shipyard had before the sinking?
Mehmet Karabeyoglu: In reality, I don’t think our image really has been damaged. However, we have deliberately not sought to be insensitive and pretend nothing has happened. We could have been quite aggressive after the Turkish experts report. But we didn’t. We just wanted to get on with building yachts and yachts for people to be proud of and confident of. We will allow our yachts to speak for our reputation.
MegayachtNews.com: What do you think the superyacht industry can learn from this tragedy?
Mehmet Karabeyoglu: Save for an exceptional weather event, no single event causes a sinking. BEAmer had no axe to grind, and we as an industry should look at their recommendations seriously. I know that some of their comments are directed specifically at the French flag, but all flags should be discussing the merits of BEAmer’s recommendations, such that they are.
However, I do believe the sinking of Yogi was a wake-up call to the whole industry to remind everyone in the industry that we build ships that can and should be able operate in harsh conditions, and everyone associated with yachts must be trained and competent not only to meet those harsh conditions but to be prepared for those harsh conditions. Whether it is regular ISM drills, regular reviews of the class status of the vessel, or a serious reconsideration of how yachts are to be used and who should crew them.
Equally we should take a step back and remember that these are not toys but ocean-going vessels, with a responsibility to keep those onboard safe, but equally, if we are to be taken seriously by the wider maritime community, we must be serious about our obligations to that wider maritime community.

Excellent interview! Extremely well done and clarifies so many thoughts of what caused YOGI’s unfortunate sinking. Mr. Karabeyoglu is to be commended for having the courage to give the interview.
All best …Michael

Good to see these comments from Mr. Karabeyoglu as I am sure it was hard to know what to say after this type of incident. As Mr Karabeyoglue rightly points out, “no single event causes a sinking” and after reading the report it certainly seems impossible to know what really went on, and at what point the situation got to a place of no return.
Thanks for keeping us up to date on this.

Mehmet Karabeyoglu issued further comment over the weekend. “BEAmer’s general recommendations do merit consideration,” he says. However, he largely questions why some of the agency’s initial conclusions, released in a first draft presented to the shipyard and other pertinent parties for commentary late last year, do not appear in the final report. “We do not expect our view to automatically hold sway, but what is disturbing, in several places, where we pointed out errors in the conclusions drawn by BEAmer, in the final report we now read altered hypotheses which support the conclusions we criticized,” he states. Here is the rest of his statement:
“The alterations circumvent failings that we identified. For example, in the draft report BEAmer mentioned that the speed of Yogi was 16.7 knots at a 60% load on the engines. From our own sources, the speed originally cited by BEAmer was close to being correct. We advised them that the loading was incorrect, because at that speed, and if the 16.7 knots speed was correct (which we believe it was), then the correct engine loading would be 100%. Pushing any vessel in those conditions at 100% load is not wise. BEAmer decided to maintain the 60% loading and reduce the speed of the yacht in final version.
“One has to ask why? Even though the yacht’s AIS was turned off, we know exactly what time Yogi left the Dardanelles, there are pilots’ records which clearly state when she cleared, and we have the captain’s statements as to when the engines overheated. A simple calculation which takes into account the distance travelled and the time it took to travel that distance places the speed at around 16.7 knots, and of course we have the original sea trial reports that confirm this speed can only be achieved at 100% load.
“We also presented them with photographs taken from the rescue helicopter which shows the boat upright before the sinking. This photograph is significant, although we don’t want to go in details at this time. Photographs also show aft deck cushions, which were stored in the beach club, floating next to the yacht. This raises the question, how did they come out of the beach club where they were stored?
“We also note that BEAmer accepted that assertion that the crew we were able to see 1 metre of water in the beach club by using the outside watertight door. When we read the draft report, we thought that it was impossible to open that door inwards against 1 metre of water. With the assumption there was no water in the staircase, we calculated the force needed to open the door using the handle at the centre of the door more than 460 kg of force is required to open the door. If it is pushed on the farthest edge rather than at the centre, more than 230 kg of force is required.
“In the final report and AFTER we pointed out the amount of force needed to open the door, new words were introduced into the report that state there was a lurch to port which forced the door open. But instead of looking at these human issues in any serious detail, BEAmer has chosen to concentrate on stability issues. It is common knowledge that stability of yachts and ships are based on different scenarios, and following inclination tests by computer software; this is carried out with the inspector of flag authority. If this test is ever doubted, due to a change in weight of the yacht, or other loading conditions, this test must be repeated immediately, which can be done at any shipyard anywhere in the world as long as a surveyor from class and/or flag state authority is present.
“The yacht was delivered in May 2011 and cruised extensively during the entire summer season. When she was back at the yard for warranty repairs, which were largely painting and other minor issues, initially the owners wanted to repeat the inclining test and, yes, that was on the original warranty list. Yogi was in the shed for painting, and this test could only be carried out in water after the re-launching. When we received the final warranty list, the request for the stability test had been removed by the owners, so this was not performed. We have the emails which prove this, including the email from the owners’ representative with the final warranty list.
“Finally, following a short sea trial the warranty list was signed off and Yogi left. There was never ever a suggestion that the yard had refused a stability test, and there was no reservation on the warranty list relating to stability. We can only conclude that stability was not an issue; otherwise the captain would not have sailed for months if he had doubts about stability and certainly would not have sailed into poor weather after the warranty work if he had serious concerns about stability. The only inclining test done to date was done by ABS on behalf of the French flag before delivery. It was valid then. It is valid today because no intervening testing took place.
“As you can see, it is extremely alarming to us that BEAmer has concentrated on the initial warranty list, not the final agreed warranty list in which the owners had removed the inclining test. BEAmer were supplied with the complete signed-off warranty list, yet BEAmer have only published a single page of that warranty list, and not only that, but that page is incomplete. BEAmer had one full year to complete the report, yet this critical point, which throws a serious allegation at us, was excluded from the draft we were asked to comment on. Even if it is true, as BEAmer claim that this allegation only gestated in January, they did not seek to verify this serious allegation.
“The allegation that important build modifications were not communicated to flag is nonsense. Elsewhere the report states that the additional keel and the drawings were approved by ABS, who had delegated flag authority. The draining circuit was an owners’ post-delivery request for which the owner had not sought class approval.
“BEAmer claim that damage stability criteria did not take into account the most adverse situation (two contiguous aft compartments flooded), but they also concede that such flooding contingency is not a requirement of Division 242 and was only the subject of a French flag internal memo that was sent neither to ABS or us.”
“Yogi sank in 7-8 hours after the initial incident. It is hard to fathom how the water flooded into three watertight compartments. The yacht had electrical power right up until the final sinking; why weren’t all three bilge pumps operated to try and save the yacht?
“These few issues makes the report extremely disappointing, and we do not understand the process that BEAmer used to collect and verify evidence.”

I am really not surprised Mr Karabeyoglu has found it necessary to issue this statement. It seems to me that he has done every thing he can to help the enquiry in a bid to clear the name of his shipyard and then the French report writers armed with his information appear to have altered what they had at first written.
It is my firm belief, and experience backs me up here, that yachts and ships generally do not sink without due reason, they either, blow up, catch fire, hit something, are overcome by weather or are lost by poor practise.
One thing that does amuse me is how lucky it was that the yacht lurched to port at the very moment that someone needed to open the door

As the interior designer and stylist of I will just say here that by having collaborating for all those years with Proteksan Turquoise with Mehmet KARABEYOGLY and Hayati KAMHI, doing about 8 yachts with them, I’m proud that I had the chance to work with such highly skilled professionals people as I’m proud too of the Management team, Engineering team, Design team , and Workforce team of this splendid shipyard.
No doubt that Yogi was built to the highest standard in all ways and I think I can say this.
All I did read or see during this past year concerning Yogi was making passing from sadness to hunger because of the many stupid thing I saw or heard.
Now as of this final investigation report that I have been reading about two days agoo this leaves me a bit harmless with all those conclusions and writting !!! I will not extend myself as Mehmet and many here have been pointing out evidence.
To conclude, thanks Mehmet for your great analyse of all this and your courage and thanks to all Proteksan Turquoise people,that are real professional people to my eyes.I hope now this page will be turned of.
Sorry to readers for my poor English writting
Best
