Nothing huge, but the accumulation of many small things that add up to the margin of victory. Get your critical increment of Fast at a North U Trim Seminar. North U Trim Seminars teach the latest in racing skills with an emphasis on practical, proven, real-world techniques that will help you win.

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 too
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.

You are so close…
There’s no magic.  A little here, a little there… It all adds up.

Trim Simulator…
The exclusive North U Sail Trim Simulator models upwind trim and performance as never before. Years in development, the simulator uses the power of the North Sails Design Suite to model upwind trim and performance with unprecedented accuracy – in both the depiction of sail shape and performance data.
