We occasionally have lazy days where we just raise the main (perhaps remembering our days with a Freedom) and head out. Using a single sail is a lot easier with just the genoa which you can roll out and in without heading into the wind as well as easily reef. But not when you have to point! We certainly do point better and sail faster with the main and genoa, but the main alone works better than I would have expected. (Or I just don't know how to sail with two?)
