SailTimer is already incorporated into MacENC. It provides the optimal tacking/gybing angles (laylines plotted right on the chart for an active waypoint and angles from the position icon drawn). No plans to add calculations/adjustments for currents because the data for currents is not accurate enough for any given geo-referenced location at any given time. While its useful for planning, the data is not accurate enough for real-time generation of tacking angles. We also realize that typically wind speed and angle do not remain consistent for an entire leg and as such drawing anything more than laylines for the current tacking angles would not be accurate. So while such plots are entertaining they rarely reflect the realties of the actual locations of where tack or gybe would occur.
