Sail Crossover Chart

Reading your chart

Work through the tabs in order: mainsail first, then headsails, then downwind and reaching. The full crossover puts the headsails and kites together, with the main's reef lines dotted behind them.

Set the top of each range where the sail starts to get hurt, not where you once carried it. Click a sail (on the chart or in the inventory) to edit it: drag its points, double-click its outline to add a point, or double-click a point to remove it. Most sails lose angle range as the breeze builds.

Where two sails on the same stay overlap, tick Preferred sail to see which one to use. By default the boundary sits halfway between the two sails' sweet spots. To move it, click one of the sails and drag the dark points on the dashed boundary. The readout marks the preferred sail with a star, and the PredictWind and Expedition exports use the same choice.

Import a chart

Load an existing crossover from PredictWind (mainsail or headsail .txt), Expedition (.xml or .txt) or a spreadsheet grid. It replaces the matching part of this chart.

Export to navigation software

Each file is a grid of true wind angle (35–180° in 5° steps) against true wind speed (1 kt steps), with one sail per cell.
