North U. Boat Speed and Racing Trim
The North U Racing Trim Webinar is a four session course focusing on boat speed and sail trim.
Race and Win
Bicycles, bobsleds, sailboats. No matter what you race, you’ve got to be fast to win. If it’s sailboats you race, then the North U Trim Webinar is for you. North U Trim Webinars teach the latest in racing skills with an emphasis on practical, proven, real-world techniques that will help you win. Even if you never race the webinar will teach you how sail faster and with better control in all conditions.
Championship Performance
The difference between mid-fleet and podium, between good and great, between crossing and ducking, between holding a lane and fading away, is just a couple percent. Nothing huge, but the accumulation of many small things that add up to the margin of victory.
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: Better balance, more control, faster speed.

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.
Symmetric Spinnaker Trim
The rules of initial spinnaker trim are just that: initial trim. From there we can change spinnaker shape, performance, and control through changes in pole position and pole height. You’ll learn reaching techniques for better shape in light, moderate, and heavy air conditions for close, beam, and broad reaching. You’ll also learn critical details in running spinnaker shape, weight placement, helm balance, and trim that will allow you to sail faster, deeper, and with better control.
Asymmetric Spinnaker Trim
Asymmetric spinnakers – so simple, so complex. The simplicity of asymmetrics, with a fix sprit, makes it tricky to optimize performance over the full range of wind angles and wind speeds. With so few controls, what can you do? In a word: Plenty.
Asymmetric Reaching Trim seems easy – but great asymmetric speed at all angles involves adjusting shape and technique to suit the conditions, boat, and sail…
Asymmetric Running Trim is particularly tricky, as you can’t square the pole back. We teach techniques that will allow you to sail faster, deeper, and with better control. We’ll explain how changes in tack height, sheet trim, lead position, weight placement and helming provide nuanced but critical improvements to performance. We’ll also explore the opportunities, advantages, pitfalls, and techniques of wing-and-wing asymmetric sailing.
Jib & Main Trim
The Webinar also covers sailing reaches and runs under Jib and Main. ‘JaM’ sailing uses different angles and techniques than spinnaker sailing. Learn how to minimize distance, improve balance, and maximize speed when sailing or racing without a spinnaker.
You are so close…
There’s no magic. A little here, a little there… It all adds up.
North U Trim Book
Written by Bill Gladstone, the North U Trim Book covers every facet of sail trim, boat speed, and boat handling. It is the compliment to the acclaimed North U Racing Tactics. The seventh edition includes over 200 information packed pages. You’ll learn how to trim and shape control performance – upwind and downwind, for both symmetric and asymmetric spinnakers. Special sections on Trim Solutions solve the most baffling problems in performance. Excerpts have appeared in SAIL, Sailing World, and Yachting. You can add the Trim Book to your registration.
