Are you seriously questioning the importance of precision in naval travel?

Are you seriously questioning the importance of precision in naval travel?

I was questioning 2 things:

1) the fact that precision wasn't available to them via maps and star-charts to a reasonable degree already.
2) the fact that if something like that was needed, that the Alliance wouldn't have built it already. It's called an investment, and unlike crops (that we're assuming came from Demon world), it should have been easily possible.
