Thank you for the input thus far and I want to clarify what I am looking for. The charter boat companies has previously approved me as a captain for a 42'+ CATS with basically no sailing experience:) I have/had enough sense that I knew this was a bad idea to captain that size of vessel without experience. We have hired a wonderful captain for every trip - he has taught me a lot and has become a family friend. I will continue to hire that Captain because our entire family has become close with him. During our last trip - a couple was staying at Scrub Island and spending a week at a sailing school because they purchased a 42' CAT and were going to sail around the world. I am not seeking certification to rent a CAT - I am seeking some defined training/course on sailing to improve my knowledge/experience for handling a CAT because I desire to learn more and believe in training/learning. I will take a look at the suggestion from Schwendy and LianeLeTendre..
