Some yachtsmen and cruise ships rely on the Red Sea as a gateway for around-the-world journeys. Most pirate activity has traditionally been concentrated in areas not frequented by leisure ships: the southern part of the sea and the Bab-el-Mandeb (the Gate of Grief), a strait between Yemen and Djibouti. But patterns are slowly trending north. Already there have been 17 attacks in 2011, all on cargo ships and tankers—none on yachts or cruise liners.
