How do the events in this chapter characterize raftsmen?

The events in this chapter characterize raftsmen somewhat like pirates. When Huck and Jim are going down the river hoping to find Cairo, they come across a large raft with 13 drunk people on it. The men were around a fire getting drunk and telling stories to each other. A few of them also started to fight each other. They were pretty drunk resulting them to be obnoxious and foolish.
