To tell you the truth, I haven't jibed much, maybe once or twice.
The sail pulls the tack line forward of the foretriangle, but that's not to say it doesn't rub against the drum at some point. Since it's just my wife and me, we don't use it in winds that would cause a ton of load. I've thought about using the pole as suggested above, or getting a sprit or long anchor roller as an improvement, but haven't done anything yet. We haven't even used it this year - there was either no wind or too much wind, and in the wrong direction.
