First of all, thanks! The cargo ships are fun and interesting and I'm sure that a few changes will occur here and there but they are quite good as a first release. Seven is quite a few to click on individually, and it would be nice to have some chart like the trains have in the timer tool. Honestly only a suggestion as a way to help forgetful people like me to remember which is doing what
I only have one out and already worrying about trying to keep up with 7!! lol.
