Boat Speed & Sail Trim Seminar

Sailing UPWIND

Sailing efficiently upwind - against the force that drives us - is a marvel of modern design. The North U Trim Seminar provides fundamental understanding of the forces behind upwind sailing as well as nuances of trim to optimize upwind performance.

Upwind topics include mainsail and jib trim, helming, and a special Trim Solutions section to solve the most baffling problems in upwind performance. The Trim curriculum shows how angle of attack, depth, and twist combine to control upwind power, and how to change trim to improve performance. The interactive Sail Trim Simulator allows you to see how changes in sail controls change sail shape and performance, while video clips show real life trim and performance technique.


Sailing downwind is easy. Optmizing downwind performance is tricky. Downwind sections of the Trim Seminar cover both symmetric and asymmetric spinnakers and show how the coordinated efforts of the full team provide subtle but critical improvements in downwind performance.

You’ll learn how to control and optimize spinnaker shape with refinements that take you beyond the basics. You’ll also learn how to coordinate trim, helm, and crew weight to sail faster, deeper, and with more control.

We also cover differences in design and trim technique that distinguish symmetric and asymmetric trim. Plus we cover non- spinnaker trim for those who like to sail under Jib and Main only.

The differences between good and great trim, between OK and fast boat speed, are small and nuanced. Kick your speed up a notch at the ASA / North U Sail Trim Seminar.
