Hello!

I am 23 and very passionate about sailing and everything to do with the sea. I've been sailing 16 Catamarans in the oceans since I was very young. I am now looking to take my next step in my sea education.
So my questions are as follows:
1) If I would like to sail a small yacht around the british/us
virgin islands, what sort of certificate should I get and through which company?
2) I want to start working as a yacht transporter. Across the Pacific/between countries in the
Mediterranean. What sort of
certification do I need for that and through which company?
Any information will be greatly appreciated as I am highly
lost.
Thanks in advance!
