To give you an honest answer: No.
As a US Sailing instructor that has trained hundreds of sailor, (a number of which I have crossed paths with later in foreign ports). I can give you a practical answer too. There are two schools to go to: the one I went to as it was the only one, the
School of Hard Knocks. It works but it’s slow and more hazardous. And you will probably miss some good stuff. Or, the
route of formal
certification. More thorough and much faster and safer. However, that being said, there is no instant solution to
learning cruising on a sailboat. Courses that advertise that they will take you from zero through Bare
Boat or Costal Cruising an just a few day of “live aboard training” are very miss-leading. I also teach
Scuba and the same thing goes. “Learn
SCUBA in a weekend” .........uhhhh barely and good luck! It takes time and experience. At the
school that I taught with in
San Francisco, after Basic Keelboat and then Basic Cruising, we require you to have at least 10 trips out with you in charge ( on any cruising boat) before you could take the Bare
Boat Cruising course. That’s because nothing replaces experience, where you make the decisions, the
mistakes and figure out how to solve them.
So, no, there is no
Certification required and actually, I agree with that. The
water is one of the last places that we can go and not have
government grinding us with
license requirements. That being said, professional sail
training properly done, will GREATLY enhance the speed and
safety of
learning.
