Primetime television shows and action movies have left me with the impression that it is not really safe to travel far from shore in sailboats and yachts, because of modern-day pirates that will board the boat and, best case scenario, steal stuff including the boat itself, worst case scenario kill everyone aboard and then steal the boat.
Yes, it can be true. Piracy is more common today than ever before. Some waters, such as the west coast of Africa, Malacca Straits and South China Sea can be extremely dangerous to small private boats and large merchant ships alike.
The good news is that piracy is pretty much confined to several well known hot spots, and is not rampant in every part of the world. The Caribbean, for example, sees very little piracy these days compared to days yore.
