This code was requested by JustATourist to make Privateers function more like they did in Civ 3. I just attached it to a wonder, though you can easily remove that requirement and have it as a default ability for the unit.
Plundering Gold, means it actually removes the gold from the enemy treasury and gives it to you. Capturing a ship gives you a chance to acquire a new Privateer after combat victory.
Both amounts are controlled by:
iGoldStolen = ( iGold//50 )
self.iNewPrivateerNumber = self.getRandomNumber( 4 )
So you can edit the percentages to whatever you want. Keep in mind for the random number it counts 0 so a random number of 4 is a 1 in 5 chance (hence 20%).
All the python is labeled and searching for "Trafalgar" should find all the changes.
I recommend downloading winmerge to help combine the files.

Edit: Added additional code that now displays a message informing you of how much gold you've plundered and if you've captured an enemy ship.
