Also tacking usually requires either very tight main sheet during the tack, or if I blow that... i have to reverse the tillers (all the way),
What Doug meant was to blow the main after you've started the tack, otherwise if it is tight through the tack it will act like a giant wind vane and you would have to back the rudders. Even if you have a jib up try this and you will go through and come out of your tacks much faster.
