If you want to see terrain features, look out the window. If you want
to know where you are, look at your map. If you want to know how far
you are from the turnpoint, put your ruler on the map and measure.

The lower the glider performance, the slower the situation changes, and
the less you need to navigate. The less you need navigate, the less you
need to refer to your map.

The lower the glider performance, the shorter the distance you have to
measure on the map. A 6" ruler (40 NM) is plenty long enough for you,
but often, my intended airport is much farther away than that, so I'd be
trying to use a 12" ruler.

A paper map in a big, slow cockpit is quite adequate, but it's a serious
distraction in the typical high performance glider.

Not that there is anything wrong with a big, slow cockpit...
