Nigeria and the Straits of Malaaca lead the way, again. Another suspicious yachting occurence off (well, 350 miles off) Socotra Island, in the Gulf of Aden.
A craft with the appearance of a dhow chased a yacht underway. Skipper altered course and took evasive manoeuvres to avoid direct contact. After some time two more crafts joined the dhow but finally they gave up the chase.
Socotra Island sits off the coast of Africa and may be an interesting place to visit.
Socotra Island is the largest island of the Land of Sheba...Giant spiders? Map: here. Its neighborhood isn't the greatest, though.
