sorry but since my German is very poor I ll write in English. I hope that's not a problem
So my proposals are:
1) that the bot starts shooting the ship with lowest hp and keeps on shooting it until it sinks it or until the ship has reached a point that it needs repair.
2) to click the furthest away possible from the npc and stick to this point until the ship is fully repaired or until it gets shot at by an npc
3) when done with one bonus map to jump to the next one
4) to log back in after server restarts and jump into bonus map
5) or instead of 1) it could move around the map and to take the appropriate distance depending on your talents and cannons so that it shoot the npc closer to it (i think that's the best)
6) to work with most sea chart layouts so that people don't need to change their map settings all the time
Finally I am aware that most of them are probably impossible to make them happen. Maybe I am not really aware since I am not a programmer myself but I can imagine.
I am sure that your bm bot bluedra will be as perfect as your glitter bot
