It was a busy day in Falmouth as a team worked to remove the mast of M5 (ex. Mirabella 5) before the yacht's year-long refit. To destep the world's largest mast at 89 meters and 45 tons was no easy task. In fact, it took 4 cranes (including one of the UK's tallest cranes), 40 staff and over 8 hours.

Marine Results helped coordinate this feat. "Unstepping the rig is no small job," noted Ed Danby of Marine Results in Pendennis' press release. "To give you an idea of the size of the job, when we remove the boom vang, this alone is 9.5m long, weighs 900 kg and is capable of pulling 112 tonnes." And that's just the boom vang!
