OK, I understand better.
The game was originally designed for 600x800 and some people complained that the stretching and small icons/fonts at newer, wider resolutions was too small to read so I hardcoded a factor into the scripts for the land/sea displays. For better treatment, I copied an option from ERAS to this version that will allow you to rescale those, separate from the screen resolution where you can choose the scaling factor with a slider.
Update the COAS scripts from the Itch update, load your saved game, go to Options, click HUD button lower right, and slide left to a value closer to 1.0 (you can go lower if you want). It does not take effect immediately, but if you are at sea, just enter your ship cabin, then exit.
