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 Seminar is for you. North U Trim Seminars teach the latest in racing skills with an emphasis on practical, proven, real-world techniques that will help you win.

Championship Performance
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.

In addition, the course covers the latest in spinnaker trim and control for both symmetric and asymmetric spinnakers.

There’s More…
But that is not all! The course also teaches proven boat handling methods that put you in control. You’ll see how to set, jibe, and douse all types of spinnakers in all kinds of weather. You will leave with the tools to make your boat handling second nature, and your boat speed second to none.

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 new seventh edition (release date: October 2015) includes completely updated graphics in 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 at a discount.

North U Trim Disc
Our revised Trim Disc shows sail trim and boat handling in full motion. The Trim Disc includes full-motion animation, photos, and new video segments. You’ll see how changes in trim change performance, and learn the latest in boat handling. We use the TRIM Disc to teach the webinar. (Overall the webinar covers about 1/3 of the TRIM Disc material.)
When purchased with the webinar you’ll save $15 on your Disc purchase.
