What’s new

Version 4.1.2 · Updated September 17, 2026

• Keep Your Course in Sight You can now set your boat’s COG/SOG Predictor to Infinite, keeping your course visible all the way to the edge of the screen, whatever the chart zoom level. This lets you keep a long predictor for your own boat while using shorter predictors for AIS targets. Enable it from Settings.
