UpWind Sail Trim Simulator

Driven by the North Sails Design Suite, the North U Sail Trim Simulator lets you explore proper upwind trim with the full range of sail controls.  Matched to specific boat designs, the Simulator provides control over main and jib trim, including mainsheet, backstay, traveler, cunningham, jib sheet, jib lead, and jib halyard  as well as the helm, and allows you to set the wind speed and vary the sea state to explore how optimum trim changes with conditions.
