A raft guide's primary job is to navigate an inflatable raft with passengers (crew) down a river in a safe and enjoyable manner. This requires that they continually assess and manage risks during the trip. A skilled raft guide is able to recognize river features and understand their effects on a raft, and what is required to navigate among or around these features with passengers. On rapids where the potential risk of injury is high, it is the guides responsibility to keep the raft from overturning (flipping) or passengers from falling overboard.
