Hey Sheartip,
Welcome aboard. Be careful Formula is very addictive.

You'll be fine as you are a better sailor than me. Here are a few things Ive learned to make it easier.
1. Formula boards are designed for upwind/downwind... Not very comfortable reaching...
2. Uphauling...I've made an easy uphaul like the guys said. Start with a spare 2feet of rope. Tie it to the bottom of the rope to the uphaul and make a loop at the other end. Keep tieing knots in the rope until it is about the right length when uphauling. Other than that its easier when the nose of the board is to wind.
3. Harness lines. Get adjustable ones around the 26" mark. One big tip I received from the better guys was to really shorten the lines for upwind. Makes it much easier to apply rail pressure to point properly.
3. Upwind. Really push the foot of the sail on the deck. Again helps upwind.
4. Downwind... Let off those harness lines, hang on and feel your legs burn.... Make sure that you are putting lots of pressure on the rear leg otherwise the nose dips. Use the sail COE to push the board downwind.
5. Read lots on the internet. www.carbonsugar.com (AUS-120) is fantastic.
I'll try and get out Thursday night too.. Hopefully see you all there.
