The MAIB found Simon Speirs may have died since of a intensity smirch with a commonly-used reserve hook.
The 60-year-old man was holding partial in the year-long sailing race as a organisation member with group Great Britain.
He lost his life in November after being cleared overboard in the Indian Ocean, and was the third Briton to die competing in the eventuality in the last two years.
The MAIB has released a reserve circular after a rough review suggested what happened.
The report said: “A reserve issue identified during the review was that the offshoot on the finish of Mr Speirs’ fasten had turn held under a rug cleat, ensuing in a parallel loading that was sufficient to means the offshoot to crush and eventually release.”
The offshoot used is pronounced to be approved and an general customary opposite the sailing world. It is designed to withstand pressures of over one ton when loaded longitudinally.
The obligatory recommendation to sailors is: “To forestall the strength of a reserve strap fasten apropos compromised in-service due to parallel loading on the fasten hook, the process used to anchor the finish of the fasten to the vessel should be organised to safeguard that the fasten offshoot can't turn caught with rug apparatus or other equipment.”
Mr Speirs was given a sea funeral at his family’s request, with a service led by his skipper.
Organisers call the Clipper Race “one of the biggest hurdles of the healthy universe and an continuation test like no other”.
Previous sailing knowledge is not compulsory to enter the race but any of the 12 competing yachts has a entirely competent skipper on board.
The year-long eventuality costs £49,000 to enter and is the brainchild of Sir Robin Knox-Johnston, the first person to cruise solo uninterrupted around the world.
London company executive Sarah Young, 40, died during the race in 2016 after descending overboard while sailing from China to Seattle.
And in 2015, Andrew Ashman, 49, from Orpington in Kent, died after being hit by a wire while competing in the event.
Following Mr Speirs’ death, Sir Robin Knox-Johnston told Sky News he would concur entirely with the MAIB which will tell its full report after this year.
