Single females answering crew ads.
Never assume, when signing up to travel alone with an unknown male, that he is NOT going to hit on you.
I've seen it from the BVI to Baja... same story... she's so shocked that he came onto her like that/the ad didn't say anything about a "companion"/I only expected to be crew/etc. etc.
You don't have to assume the worst of men, just please don't act so surprised.
