I'm not quite sure what you mean by connection to the bow. The pole should attach to a ring on the front of the mast a foot or so above the boom. The guy goes from the windward clew of the kite, through the clip on the end of the pole and back to a block on the quarter behind the sheet winch. The sheet goes from the leeward clew straight back to the other quarter block. The height of the pole is set by the uphaul and downhaul and if they are both led to points above and below the pole ring on the mast thay shouldn't need to be adjusted. There are a few other threads on this forum which give loads of details but here's a pic
