I have been a captain looking for crew as well as crew looking for a boat. In short....it works but with "caveat emptor" The screening process starts with e-mails, then phone calls, (as you can tell alot about a person by their voice), a lot of references and reference checking, hopefully one may actually know some of the references ,then a face to face and at that moment of getting to know someone, after all due diligence a decision is made, to go or not go. Sometimes people misrepresent....its kinda like a job interview where one has to read between the lines about a person. I had one crew who represented themselves as a seasoned sailor and then got scared and wanted us to turn back 400 miles out!!! Hope this helps.
