In another 12 months or so I will have to make the decision about which way to continue our circumnavigation either Red Sea or around South Africa. It is not an easy decision and there are lots of considerations including (but not limited to): which set of destinations is most interesting since the two sets are so different, distance, and how do you compare the pirate risk to the weather risk around the Cape (of Storms). Lots of boats do the Red Sea route but with care - travelling in convoys, having the significant naval forces in the region keep an eye on you, no lights, AIS, taking down radar reflectors, restricting radio use (heard of one convoy that switched their radios to Canadian frequencies and only talked to each other on the Canadian Coast Guard channel (not likely to be monitored by the bad guys). I agree that a blog with positions does not make much sense.
Finished the circumnavigation in early February in Grenada. Have to work on a book project for the next several months so the boat will be waiting for next year.
