On February 26th, as I finish this, we caught up with s/v Joseba of France and Chulupa of the U.S.A., and we plan to travel the corridor with them. They are two of the three other boats in our group. S/V Senang of The Netherlands has taken the coastal route to cruise with German-speaking vessels. Eduardo, on Joseba, told us about an encounter they had just a few days ago when a 100-foot boat tried to get him to stop while he was sailing in an area about 100 miles off Socotra island, and they were waving a U.S.A. flag by hand off the bow, but did not contact him on radio. [We think they did not speak English.] He motored his boat erratically, winding all around, as well as he could, and they finally gave up. We consider any vessel that does not use radio contact for permission, a threat in this situation, and would do the same. If we see guns, we set and pitch the EPIRB!
