This would be a large add on to the game, but could be fun. This is just a rough outline and needs fleshing out, so input would be greatly appreciated.

My idea is a player can build and maintain 3 boats, 1 small, 1 Medium and 1 large.

The items needed to build and maintain are rare and currently not available in game. Luckily a Naval Base has just opened up next to the construction site, it will only take you 3 hours to rob it and start gathering the required amount of the four materials needed to build and maintain the boats.

Of course you cant send a boat on a tour without food and water and luckily for you a resturant has just opened up near the naval base. It will only take 3 hours to rob it and start gathering the required supplies.

So you stock up your Small boat and send it off on it's 1 day voyage, it returns with a few types of what appears useless materials, they are market and NPC prohbited. Good fortune, they happen to be the exact materials the captain on your medium boat is asking for. So stock up on food/materials and send off the medium boat for it's 2 day voyage.

It returns with different, but also useless materials, but you know what your large boat needs. so throw the food and new materials on, after 3 days it returns with a whole host of different materials.

Fortune continues to shine on you as a "Narcos Equipment Store" just opened in town. It manufactures guns and armour for your Narco's for as long as you keep up the materials they need. It's automated so the Narco's will grab the guns and armour as needed.

Eventually they will all be equipped. As your % of equipped Narco's rises, so does your production, delivering a little more of everything everyday, which will be handy as those subs need stocking.

Mishaps do happen though, as the day ends and reset happens you find a few guns missing, some armour damaged, so best to keep that narco equipment production going.

Those boats need maintaining and restocking, so need to do those occasional Naval andResturant robberies happening (with achievements maybe?)

Anyway, this is just an outline of the whole idea, let me know what you think.

I did have some non cartel related ideas around the smuggling suggestion. I think this is kind of like them in a way but I also like that it introduces some additional jobs.

The thing that jumps out to me as a bit of a downside is the need to use all three boats over the course of several days to have an outcome. But the three combined is still faster than a smuggling run so thats probably not so bad.

I will try and think on it more and come back with additional feedback, this is just my initial reaction. Overall I like what it would bring.
