River and canal outlines
The water outlines along the Recalada - San Lorenzo passage: the Río de la Plata access channels and the Paraná. The app uses them to draw the river banks in its river voyages.
They are derived from OpenStreetMap water polygons, cut to within 3 NM of the planned track.

Not for navigation. These outlines are for drawing a training simulator. They are not a chart and must never be used to navigate a real vessel.
