The North U Racing Trim Seminar is offered as a one-day course focusing on boat speed and sail trim. We will go upwind in the morning and downwind in the afternoon.

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.

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

Adjust every control. View from every angle. Test in a full selection of wind speeds and sea states. See the results. Learn.

Use it at the seminar. Take it home and practice. Learn More.

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.  All material will be delivered to you on the day of the seminar.

North U Trim Drive!
Our revised Trim Flash Drive shows sail trim and boat handling in full motion. The Trim Drive includes animations, 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 Drive to teach the class, but it is packed with more info than we can cover in a day. You can add the Trim Drive to your registration. All material will be delivered to you on the day of the seminar.
