Agree with your additional info which is good & that the poster has a few things to consider including if he is on the E or W coast of Oz.
My comment about the Southern Ocean was based on some reading that I had done about how far south pirates are venturing but on doing some further research
I agree that you should not need to go too far south of the Cape of Good Hope. I personally wouldn't want to do the Suez route but of course many do but it is a bit like rolling the dice with those damn pirates.
So damn frustrating I same a recent documentary filmed from a US warship & helicopter where they filmed the pirates throwing their weopons over the side so that when they eventually boarded the pirate vessel they had no weapons so they could not charge them with piracy
. Seems we are too damn soft & nice to them.They must be laughing their heads off at us in these situations.
