North U Racing TRIM CD-RomEnglish
By Bill Gladstone
Bicycles, bobsleds, sailboats - no matter what you race, you've got to be fast to win. If it's sailboats you race, then you need the North U TRIM Disc.
The North U TRIM Disc puts performance in motion, and shows how changes in trim change the sailing performance of your boat. Use the inter-active "Sail Shaper" to see how different sail controls change sail shapes. Understand how to adjust angle of attack, depth and twist to match different sailing conditions. Detailed trim guidelines are provided for mainsail, jib, genoa, spinnaker, and asymmetric spinnaker trim.
In addition to sail trim, the Disc covers boathandling topics, and shows the most up to date techniques for spinnaker sets, jibes and douses, for both conventional and asymmetric spinnakers. Through video, animated graphics and 100s of photographs, the TRIM Disc covers the full range of trim and boat handling topics.
