What is the purpose of the Lead and sweep boat?
The lead is usually someone who is familiar with the river you are running and has the skill to run it in a safe manner. No boat should get ahead of the lead boat. The sweep boat is the last boat of the group. This boater should also be a good paddler and should be well versed in river rescue. The speed at which the group moves down the river is determined by the slowest paddler. If the group starts to get spread out the boats near the front need to slow down and wait for the boats in the rear.
