Very good observation there JtD. Indeed gliders load water ballast into their wings when going out on days with good conditions. The increased wingload will shift the polar curve to the right, allowing them to fly at higher speeds with less sink. Without water ballast a Discus 2b will sink 2.2m/s at 170kph. Loaded with 200 litres it'll sink only 1.4m/s at the same speed
