Hi guys thanks again for all the comments
The course is basically under Australia, Cape of Good Hope, North over the equator around Hierro Island (Canary Islands) under Cape Horn then home. I have a weather router to try and miss the very worst weather, but of course at 6 knots you can only do so much to get out of the way.
There is a big trade of between distance sailed and most favourable currents and wind so i don't plan to go too far North.
I am chasing sponsorship. So far Musto have come on board and B and G look promising for a radar and chat plotter.
