A pocket GPS is even better, and useful in the dinghy also.

In deep woods, GPS often has problems and does not work at all in
caves.

Hansel and Gretel. Had the right Idea Upon which, I am sure, you could
improve.

A compass is not 100% reliable. I have seen mine spinning in circles.

I like to keep a map/chart, compass, and a GPS on board. All of which
are compact and lightweight.

I visited the bridge of a cruise ship many moons ago. They used the
output from an Apelco/Ratheon loran to steer the ship. They also had a
printer hooked up that recorded loran data real time. technology has
come a long way since then, but the ancient tools are still viable.
