5 key factors for success

5 Key Factors for Success

  • Trim Spinnaker with Constant 3 “ to 6” Curl

  • Square the Pole Visually By Vertical Luff and Vertical Center Seam

  • Keep Windward Clew (the tack) Slightly Lower

  • Luff Breaking Too High – Pole Up, Breaking Too Low - Pole Down

  • Always Remember to Have Fun!
