I have The Palm installed and I love how it keeps th mainsheet clear of the transom. Assure that you have the proper tension on the large rigging ring.I pushed the boom all the way out and then tensioned the shock cord attached to the boom gooseneck assuring the mainsheet clears the transom. I used a rigging ring placed around the gooseneck to allow attachment of the shock cord with out interference and attached shock cord with hog ring eliminating bulky knot..
