The 18-year-old, who died from her injuries in a Jamaica hospital, had left Britain a decade ago to sail around the world.
Bethany Smith, 18, is thought to have died in hospital from multiple injuries after the accident on board luxury 60 metre-long schooner Germania Nova, which was berthed near Portland, Jamaica.
A GoFundMe page set up to help her family says she "fell off the mast" of the yacht on Tuesday.
According to local newspaper Jamaica Observer, she was cleaning the mast of the vessel "when the ropes became undone and she fell onto the deck".
Miss Smith wrote about her travels in a blog with the motto "Live life for today, you never know what tomorrow will bring".
