That's an interesting conclusion to come to in the absence of physical evidence or any witnesses. While I agree with the recommendations of what MAY have happened, it in no way can be substantiated that that is what actually happened.
It is a shame the hull was not recovered as it might have given a few more clues to what happened
There has been a lot of discussion about it on the YBW (British) forum after the accident occured
http://www.ybw.com/forums/showthread.php?396906-4-British-yachtsmen-lost-at-sea-Press-Statement-Yacht-Cheeki-Rafiki&highlight=rafiki and since the report was released
www.ybw.com/forums/showthread.php?429092-Cheeki-rafiki-maib-report but there is still a lot of conjecture over what occured
The MAIB website
www.gov.uk/government/organisations/marine-accident-investigation-branch has some interesting stuff on it regarding the reasons why accidents have occured and it is interesting to look at various accidents over the years and what was found in the subsequent investigation
