Unfortunately not, but I have done a couple of dives at the continuation, the Hanish archipelago, in Yemen. Those islands are dead volcanos, each with a crater at the top. There isn't a lot of coral but there IS a lot of life. I don't think there's much in the way of infrastructure in the Farasans, from what I can remember from articles in various dive mags by Erik Bjurström, a Swedish dentist and well-known underwater photographer and writer who lived in Saudi for many years.
