I have a (land) neighbor who is the original owner of a 70's era Cal 34. He still has the original main! He puts it on the boat every year, but probably only shakes it out once or twice a year. It appears to be a common fix for a quick setup sail. I want to know what you are doing that it takes 30 or more minutes to fly/douse the main over just the jib. I leave my main halyard attached. It only takes a couple minutes to take off the cover and stow it, and possibly twice as long to aim the boat into the wind, remove the sail ties, and raise the main.
