We came up with this concept years ago, I still want it.
It would also be appropriately sized for a light gunboat, and a good contrast to the rather large Condor, Ahoudori, and BW gunship currently on offer for civvies.
Looks like a tugboat if we were ever to have one. I'd see this as more of a small civilian work ship that could be used as a gunship, sort of like the Pelican, but heavier.
