The 74 metre tall rig was prepped by the RBS team alongside Tony Hawker from Florida based Seahawks Rigging.
The unstepping was carried out earlier this month, shortly after the sailing superyacht (formerly known as Salute) arrived into the Balearics.
Steve Branagh, founder of RSB Rigging Solutions, said: “We have hit a number of impressive milestones in the last few years giving us the well earned reputation of being the ‘go-to’ rigging company in the Mediterranean.
“The team we have built over the years is capable of handling all situations, acting fast to find solutions for any mast, rigging, and rope related issues.”
The refit will be carried out in collaboration with Astilleros de Mallorca, and Mr Branagh added that the whole process will take around three months, with the mast due to be restepped in September.
Launched in 2008 by Perini Navi, Bayesian is one of the 50 largest sailing yachts in the world and her mammoth mast supports a total sail area of almost 3,000 square metres.
