I had to pay what seemed big bucks for a boot a rig right$50.00 I have spar tite in hull 27. I check it occasionally to make sure it is not working loose. Mine does not have a set screwit is quicker to set up after the mast goes up because there is no adjustment. I know a J-29 owner who states he adjusts the partners with the wind conditions. that is the trade off.
