If I were asked to name the most important skill a deckhand should have, you might be surprised. It's not some technical ability or deep knowledge of boat handling or anything like that.  It's enthusiasm, combined with confidence and a sincere willingness to learn.  If you have these traits you will go far in a yacht crew career. In fact, they are the traits you need most in order to take advantage of a boat job employment opportunity to begin with.  If these things don't come naturally to you, do make an effort to cultivate them.  See my Dynamic Deckhands page for more about this.
