The pole is set in the pole ring or pole track fitted on the front of the mast. The pole is held up by the pole-up control and is held down by the pole-down control so that the vertical angle of the pole can be controlled. The end of the pole which is opposite to that connected to the mast is connected to the guy by means of a clip and the guy rope is in turn connected to the clew of the spinnaker. By hauling in or releasing the guy the crew is able to set the pole at the correct angle to the wind. This normally means running the pole at the same angle as the boom, though it may be overtrimmed (let forward) slightly on a dead run. Look up guy in Wiktionary, the free dictionary. ...

This is usually achieved by releasing the guy end ("tripping the pole"), dipping the pole round the bow and connecting it to the guy on the other side. On smaller boats the pole might be tripped at both ends, turned 360° and reconnected on the new side.
