STCW (Standards of Training, Certification and Watchkeeping), is now required if you are sailing as paid crew. I have heard that without it you can be refused entry into the Bahamas and the BVI. I have never been asked to produce any personal documentation of qualifications or credentials, anywhere in the world except the US (operating a US flagged vessel, but not foreign flagged vessels), even when operating freighters and tugs. Vessel papers, yes, almost everywhere. Passports EVERYWHERE, these days.
