Here is another fortification; building off of my 50 mm generic square, I put in towers for use as a Watchtower which in the game is also in the size category large, just like both Forts. The tops are socketed again to allow easy switches to denote controlling player changes, and I plan on putting together more flags to match other fleets’ colors once they are painted up...

...the dock is only for aesthetics, it is not attached to allow easy removal during play if measuring to that side of the piece.
For anyone else modeling 6 mm structures, the ladders are not printed, but are cable zip ties. At scale, they end up being about 16 inches wide, and drybrushing the ratchets picks them out as if they were rungs.
Next up on the terrain side, I am working on houses to go alongside a waterfront.
