This is where my Star experience comes to play.
1. Heel the boat to weather to expose the Genoa
2. Use the spinnaker pole as a whisker pole. I have also used light weight whisker poles that can telescope to enable the use of smaller head sales.
3. Remember that higher reaching angles require the pole to move forward.
4. Backstay TOTALLY off. Loosen the turnbuckles for the backstay as much as you dare. The rig should be max forward going downwind. Ease jib halyard to bag the sail.
5. Ease the vang, don't tighten it. Need to open the top of the main, exposes more sail area.
6. Related to 4 above, shrouds should be loose. In 5-6 kts of wind, I would try 900 uppers, 700 lowers. When you turn upwind, shrouds should just be kissing slack.
