The Maritime Accident and Investigation Branch (MAIB) has recently published the investigation report into the loss of the UK registered yacht Cheeki Rafiki in May 2014. Despite an extensive search that found the upturned hull of the yacht, her crew of four were never found and are assumed to have not survived. In the absence of survivors and material evidence, MAIB claims that the causes of the accident remain a matter of some speculation. However, it is concluded that the yacht capsized and inverted following a detachment of its keel.
The yacht’s upturned keel-less hull was seen just twice; once over 36 hours after the skipper’s last voice call from the high-sided container ship Maersk Kure conducting a track line search, and a second sighting was by personnel from USS Oscar Austin who examined the upturned and partially submerged hull, providing the only imagery on which the MAIB could base their report, but could not recover it.
McCourt explains that, in the report, the Maritime and Coastguard Agency has come into the line of fire. “Complex and vague commercial versus pleasure craft definitions and the boat’s ability to slip through a survey net are inexcusable,” he says. “Clarity and enforcement are long overdue.”
The report also covers the construction of Glass Reinforced Plastic (GRP) hulls in considerable detail and highlights the hidden menace of the internal matrix detaching from the hull, which can only be properly established with a thorough survey by an appropriately qualified person.
“Given the nature of life for this type of craft, grounding is not an unusual event but can lead to catastrophic loss if not identified and rectified,” adds McCourt. “Beneteau come under uncomfortable scrutiny but have made their own improvements in construction since commencing building the Beneteau First 40.7. Nonetheless, the design makes it hard to detect when the bonding is starting to fail. I can imagine they aren’t the only manufacturer to which this might apply.”
To identify synergies with the superyacht sector, McCourt advises that the report should be a salutary reminder to all captains and crew of the need for a measured and carefully considered passage plan, and that adequate preparations are needed to manage any emergency situation on a long ocean passage. “At some point, when flooding was becoming an issue, preparation of the life raft and EPIRB would have been prudent,” he concludes.

Prior to losing contact, the skipper had expressed growing concern over water ingress, but had not identified the source. “It is undeniable that the hull of Cheeki Rafiki suffered a sudden and catastrophic failure, causing her to capsize,” explains Adrian McCourt, managing director of Watkins Superyachts. “The subsequent investigation has established a number of factors, supported by the image of the upturned hull, which points towards the yacht’s keel becoming detached in adverse weather. Nonetheless, this painstaking report draws viable and reasonable conclusions and raises important recommendations.”McCourt explains that, in the report, the Maritime and Coastguard Agency has come into the line of fire. “Complex and vague commercial versus pleasure craft definitions and the boat’s ability to slip through a survey net are inexcusable,” he says. “Clarity and enforcement are long overdue.”
