Yes, if the soundings follow the coastline you can sail following it until landfall. For me was very useful one day with thick fog. Because the uncertainty and shoals is dangerous, but if the coast is well known, is useful.
In the same way, if latitude is known, and calculating the magnetic variation by Polaris, one can navigate using a magnetic chart (see: magnetic variation navigation.PNG)
By the way, I found the movie in a library, I remember seeing the movie when I was a kid. I hope I enjoy with it again.
