This is a good explaination of why you want to use both sails on a sloop, but you can have a balanced sailplan with a cat rigged boat too. However if you had explained using Bernoulli's principal and how there is a pressure differential between the sails that increase the forces enacted on the sails giving greater thrust at a lower angle of attack, you would have sounded much smarter. Please look up cat rigged sailboat and change the title of your video to "how to balance your sailplan"
Sorry to disagree. Not with the CE/CLR part though. If you moved the mast forward and still have just a main the boat may still be balanced. I would say to answer the question in your title. Two sails is often (not always) the most efficient way of generating sail area.

Thank you for this valuable info!!
Hey, this is a good one. Saving it to my lists 👌🏽
Glad you enjoyed!
