lower pennant
The above uses for the pennant at the top are all accurate, and if that was where the pennant was, that was likely its purpose; to prevent halyard twist or wrap with a roller furler. On my Sundance 20' I have a roller furler as well. The wire halyard only wraps on the forestay, if I roll it up to quickly or loosely, otherwise it is not a problem. At any rate, I want to also indicate that I have a pennant at the tack of my 110 jib. Its purpose is to raise the foot of the jib so that I have visibility beneath it. The second purpose is to get the head as high as possible to the masthead. The higher the sail the better it will catch effective wind. (The most consistent and stronger wind is that which is furthest from the water). Raising a sail in this manner also places the center of effort further aft thereby increasing weather helm. To counter this, you may want to rake the mast forward slightly, unless your helm has slight weather helm already.
