Thanks for the images and information. I guess I should have mentioned I am looking to build a port that is something of a backwater sort of place, not a 'high octane' metropolis. But definitely along the lines of US interventions - just with some added international players and local wannabes. Definitely a highly fictional setting but not in the "wild blue yonder", well, not too far out there. Might be a few 'oddities' tossed in the mix.
It will be the sort of place where, even if anachronistic, there will still be horse mounted cavalry and horse drawn wagons alongside any possible motor cars. And the ship loading and unloading equipment won't, generally, be the most modern but certainly able to handle large and heavy loads. That is key.
