I met a girl in Germany that told me that she took a week long course, paid $2,000, and got her license or certification thereafter. Now she's working on some guy's boat and sailing happily around the lovely little globe of ours. So my questions are as follow:
1)Is there one standard certification that is accepted worldwide for sailing?
2)Does having the certificate actually help you get a job, or is it a waste of money?
3)Does it matter who I get my certificate from? I'm in the L.A. area if that matters at all.

Thanks to anyone who can inform me.

Peace,

Sergio
