I reworked the text to be more in-line with the current version of the game (it comes from a time when cloaking devices were available to buy from the get-go) :
THESE DEVICES RENDER CRAFTS INVISIBLE TO ALL FORMS OF LONG-RANGE DETECTION. BY INSTALLING THEM, WE CAN APPARENTLY MAKE EVEN A WARSHIP DISSAPPEAR, REMOVING THE LIMITATION OF USING ONLY CIVILIAN CRAFT. THE REAL MYSTERY IS, WHO MANUFACTURES AND SELLS THEM? WHY? HOW?
Ja but it's still quite the tech jump from interrogating hookers and crafting bows to suddenly cloaking devices. I would update the "Our Origins" or "Our Fight," or even better, rename the text and entry from "Cloaking Devices" to be "Craft Interception" or something suitably piratey such as "Making her Flush" (the pirate term for converting a captured merchant vessel into a warship suitable for their needs.)
So, to add - you used to start with the Bonaventura - which is a proper warship - and we sorted needed a lore item to explain why we weren't getting intercepted by the AI.
You still need to buy a cloaking device when you make a craft in your workshop, but now that we start with civilian vessels, I can understand where the confusion came from.
So it's a engine limitation question. Which is a shame since real life mariners in the golden age of piracy would utilize all sorts of subterfuge to avoid interception such as carrying multiple nations' flags and ships papers (registrations,) which evolved into a high stakes game wherein the boarded ship captain had to guess which nationality the boarding warship was and whom he was legally allowed to capture and present the correct papers to prevent seizure of goods etc.
Obviously this is far beyond the scope of the game but I'm just trying to justify my History minor somehow.
