Silent Hunter 1 drawing tools
 

Just installed the first Silent Hunter and it works pretty well. Are there any mods that add more tools to the Charts window? It seems like the only marks that can be made are waypoints for your sub. I’m used to playing SH4 which has a lot of useful drawing tools and I’ll miss these if there none available for SH1.

I don't know if any really address what you are looking for, but you might check out Kim Ronhof's mods here:
