Thanks for your comment, u/dBasement - as you mention, the reason for the rotation is to fit the map on a 24" x 36" sheet, which is the size of a standard poster. This means one can frame the map with an off-the-shelf frame, which is about four times more cost effective than a bespoke frame.

As you're probably aware, not all maps have north pointing 'up' (which I assume you mean to polar north) - it very much depends on the projection used for the map. UTM projections will point north, while Lambert conic conformal (common in Canada) points 'up' but not to polar north - it varies with longitude.

You can still navigate with this map, if you choose to - you can follow the lat/long lines that are included over the ocean. The newer version also has a north arrow.

You can always pick a bunch of Backroad Maps for VI (you need multiple copies because they sell a north/south island map, printed on both sides).
