The Muddy Rudder is a bar located in Rivet City's lower deck.
There is a pool table on the top floor and a couple of chairs with Brock guarding the door. On both sides of the top floor are staircases that lead to the bar. Downstairs there are a few tables with random miscellaneous objects and food items like iguana-on-a-stick. All the way in the back of the bar is a Very Easy locked door to Belle Bonny's room which has a few beds and footlockers with some food items.
- 31 shot glasses, the highest amount in a single area in the game.
- Following the Trouble on the Homefront quest (regardless of how it was completed), Butch can be found here. He will join the player in their adventures if they have neutral Karma, otherwise he will tell them that they don't have what it takes to be in his "Gang".
- Trinnie will disclose the location of Belle's 'stash' after giving her 25 caps for drinks (done by giving 5 caps 5 times).
- Belle's stash is under the first bed on the left. It will be empty unless Trinnie tells the player about it.
The Muddy Rudder appears only in Fallout 3.
Xbox 360 If the player manages to get Butch into the Muddy Rudder, they can talk to him but there will be no dialogue options. [verified]
