You can certainly learn by sailing often, practicing, reading books asking questions, but it is no substitute for the proper and structural lessons from sailing school. I would take a few ASA courses, it will save time and money in a long run.
I often bumped into people claimed that they hated skiing. The next question I asked is who taught/showed you the first time. They reply, a friend.
A good sailer does not mean that he or she is a good teacher. A capable captain does not mean he or she is a good leader. Just sayin'
Good luck and have fun.
I read, think, and act independently; I don't come here to win a popular contest, nor I am here for free sex. I come here to learn, be challenged and be inspired in the art of safe off-shore passage. I am NOT afraid of dying in the sea, but I am afraid of dying in a nursing home and burdening those who I love.
I am old school; doing the right even when no one is watching is important to me.
