Championship Performance

Upwind Trim
You will learn the fundamentals of upwind performance, plus advanced techniques that balance angle of attack, sail depth, and twist in both the main and jib in order to optimize speed and pointing in all conditions. Through animated graphics, photos, and video you will see how the champions do it.

Downwind Trim
In addition, the course covers the latest in spinnaker trim for both symmetric and asymmetric spinnakers. You’ll learn critical details in spinnaker shape, weight placement, helm balance, and trim that will allow you to sail faster, deeper, and with better control. And we cover non-spinnaker Jib and Main technique as well.
