Took my ASA 103, 104 with Black Rock, sailing out of CYOA. I knew how to sail and have chartered before but the extra knowledge learned that week was tremendous. Learning from and experienced captain/instructor to gain better control of boat and the systems was key. I have become a more efficient and capable sailor. I would like to continue on to get my ASA 114 and some other certifications because you can't have enough knowledge when being on the water.
