"I recently attended the Reginasailing Ocean Theory course and I am glad I did. I did have some prior knowledge of celestial navigation which I learnt from books but I never had a clear understanding of this very complex study. Leon demystified every aspect of it through his comfortable and entertaining approach to teaching. He obviously spent much time meticulously developing techniques and tools assuring a thorough understanding for his students. Leon did limit the class to ten which afforded proper attention to each participant. Besides everything I learned it was a very fun and enjoyable week. I highly recommend Leon's course to any one interested in upgrading to RYA Ocean Yachtmaster or just seeking a higher level of sailing knowledge."
