Similar solution....
First, I am assuming that you meant changing jibes rather than tacks, cause a gennaker is not designed to tack. If you have the sail rigged correctly you can't tack anyway. That means that the spinnaker halyard block must be positioned in front of the forestay and the sheets are led around the outside of everything, including the forestay. That said, here's a solution similar to Frank's. Attach another shackle or clip to the end of the tack line so you can clip the whole thing directly to the forestay. To protect a furled sail, fashion a dacron collar with a couple of eyelets to allow it to be snapped around the sail to the tack clip. If the problem persists, maybe you need a longer tackline (the pennant attached to the tack). It should be adjusted so the tack of the sail is high enough to clear the pulpit.
