You may be right Greg. What if we took those two towlines through turning blocks on the shrouds, then back to the back beams, then across to the opposite tiller bar and finally back across to tie off and backbeam ends. Now the load during tacking is on the shrouds, but the unloaded towline will probably foul the old leeward rudder... hm... I think the beam ends or the gunwale at the transom is as good as it gets.
