Sail Trim & Boat SpeedIf you are looking to improve your sail trim and sail faster then the American Sailing Performance Racing Seminars powered by North U are for you. Taking place all across North America, these in-person seminars involve a full day of classroom-based instruction. The interactive presentations are taught by experienced North U sailing coaches.
Why Attend A Seminar?In-person seminars offer personal interaction with instructors. You can ask questions, seek clarifications, and get feedback tailored to your needs and skill level. Seminars also provide an opportunity to engage with the sailing community and make connections with other local sailors.
What Will I Learn?This Sail Trim & Boat Speed seminar covers sail trim on all points of sail. Upwind topics include jib trim, mainsail trim, and helming. Downwind courses cover symmetric and asymmetric spinnakers as well as tips for those who sail under jib and main only. See below for more information.
Who Should Take This Seminar?This seminar is geared toward sailors of all levels. It teaches you how to improve your sail trim so that you can sail faster. You can use your newfound speed to beat a fleet of one-design boats to the finish line or simply to reach your cruising destination faster.
Powered by North UNorth U has been the leader in performance sailing courses since 1980. Their programs offer the latest in sailing techniques in an engaging interactive format that makes the course fun and effective. North U seminars feature great instructors – expert sailors with years of teaching experience.
Sailing efficiently upwind - against the force that drives us - is a marvel of modern design. This seminar provides you with a 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 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 techniques.
Sailing downwind is easy. Optimizing downwind performance is tricky. The downwind sail trim courses 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 techniques that distinguish symmetric and asymmetric trim. Plus we cover non-spinnaker trim for those who like to sail under jib and main only.

SAIL TRIM SIMULATOR
The 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. Adjust every control. View from every angle. Test in a full selection of wind speeds and sea states. See the results.
The North U Performance Trim book gives complete coverage to upwind and downwind sail trim and boat handling, including mainsail and genoa trim, helming, and the trim and handling of both conventional and asymmetric spinnakers. Learn how the angle of attack, depth, and twist affect performance. See how changes in pole position change spinnaker shape. Understand your options for spinnaker takedowns. Special sections including boat handling skills and drills show you how to turn your crew into a team. Packed with illustrations, written to be read, the 208-page book will teach you techniques to sail faster.
The North U Performance Trim and North U Performance Racing Tactics books are NOT included in the registration fee, and will not be available to buy in person at the seminar. We strongly recommend you order any books in advance from the American Sailing Online Store.
To complement the in-person seminars we are offering attendees the option to also own the online classes.
