I am sorry to hear of this happening to you.I hope to cruise in a few years.(Liveaboard style).I will be single handed sailing also.
I sometimes worry that my dream will become a nightmare when I hear of this.
Maybe cruisers should run in packs.(i.e.3 or 4 boats traveling together or reasonably together)Saftey in numbers may be good.Also will the embassy help any?
The Navy always told us to travel in groups while in forigen lands,its alot harder to victimize 4 or 5 sailors and rob them etc,than if you travel alone.
Just my thoughts,
