I think of sailing as an escape. A portal that allows us to enter the world where everything is perfect. Perfect because it all makes sense. Perfect because it is the closest we can be with nature, and nature does not have the shortcomings of humanity. A storm can be understood because it is absent the sentiment of human beings, it's just a storm. Nature will present you with challenges, but not betrayal, with extreme circumstances, but not malice. Nature is neither your friend nor your enemy, she is perfectly natural. So for many, sailing is an opportunity to be themselves without apologizing, without fear of reprisal, or being judged.
So I believe that is more than a hobby for many, but less for some, a passion for many and less for others. It is what we make it for ourselves, and that's perfect.
