North U Performance Racing TRIM
by Bill Gladstone
The most complete book on modern sailing performance

To win races you have to sail fast. Performance Racing Trim shows you how. The North U Trim book treats boat speed and boat handling topics in the same accessible style as North U Tactics. The 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 angle of attack, depth and twist effect performance. See how changes in pole position change spinnaker shape. Understand your options for spinnaker takedowns. Special sections on Trim Solutions solve the most baffling performance problems, while the 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 Trim book will teach you techniques you can use in your next race.

    I recently attended a racing clinic put on by Women on the Water. Many of the topics we covered in our clinic––both in the classroom and on the water––are covered in the book giving me a deeper understanding of what was learned in the clinic and an excellent reference as I move forward in sailboat racing.
