Many large ships are showing in the wrong waters. Large vessels should only be at large ports, or in offshore waters, especially in the shipping lanes. In canals there should only be push-boats and smaller pleasure craft.
I often fly along the Gulf Intracoastal Waterway and the large ships look really out of place. These push-boats i the pic are plentiful in the shallow canals. (And big harbors also.)
I have started making some if you want them.
Offshore shipping lanes, harbor channels, and inland canals are documented so I think it would be easy to designate where certain vessels should appear?
Thanks;
