I have downloaded a planisphere template from https://in-the-sky.org/planisphere/ and (taking advantage of the designer's generous copyright permissions) have optimized it for navigators. Naturally, we are rather less interested in traditional Greek/Roman constellations, and more interested in "navigational stars".
While the download page at in-the-sky.org allows downloads of a vast number of templates, at 5° increments in latitude, south and north.
I have created one for 55° N (ideal for Canada, Northern England/Scotland) and one for 30° N. Frankly, the differences between the two versions are not that great. At 30° N there is a handful of usable stars that are not visible in Canada. But the differences are not so dramatic that one needs to produce navigational planispheres every 5°.
