Hi all, 
I made a Dockerfile with a bunch of useful weather, navigation and GIS utilities on it. 
If you don't know what Docker is, it's a way to run a virtual machine on your machine in a portable way without all of the traditional overhead of a vm.
For navigators, Docker is useful because:
1) You can install a Docker image on any computer (Linux, Mac, PC) so you can move from your boat to someone else's and keep the utilities installed.
2) It allows you to run Linux utils pretty easily if you're on a PC, without needing to know how to build them yourself. 

In my case, I run a full VM with Windows, which in turn runs Docker. 
This Docker image contains a ton of grib utilities and weather apps. Let me know if you find it useful.
