Make a world round trip by sailboat

Stating from where I live. I will go down the amercan coast. Have fun in the Carabeans. Then way down the South American coast. Then to the pacific. I want to do Pacques Island and Pitcairn, Tahiti, New Zealand and Australia. Move along the Australian coast to the Indian sea. Way to Africa. Then along the coast of Africa to Europe. And then from Europe way back to home.

I will me be buy my own boat. Or better I will join somebody who is already planing to make a round the world trip.
