I had a tad of helm a bit more on one side than the other, and ONLY when I left the 150 Genoa up after 10k....to me that was her telling me "um....you might want to reef"...on Port tack, she steered her self when the sails were set right, usually in 10k-15k, a 100% foresail and one reef.
I could set the tiller any way, port tack, and it would stay. On stbd, she would ever so slowly head up. If choppy sea, she would head up a tad faster...but I found that setting the mainsheet/boom to leeward would help as well.
What you don't want is lee helm...turning down wind. If she is heading up really fast...you have the sails in too tight, or your "stuff" down below is not balanced...not kidding: I had about 200lbs of tools on one side and forgot to balance the other, she almost tripped herself trying to head up on one tack, heh heh.....and if your rail is in the water, she has a tad too much sail...fun but if she keeps going, the sails get wet, ha ha.
