Row or paddle your raft into an eddy or easy landing spot long before you reach rapids--too close and you might get sucked into it.
Walk carefully along the shore (water sandal or sneakers are advised for protection) with the goal of finding a high perch with a view of the entire rapid. When you're descending through a rapid, it is much harder to see obstacles ahead.
From your lookout, check all parts of the rapid methodically, and make mental notes of rocks (obvious ones, sneaky low ones and ones that suck the current into them), chutes, hidden rocks lurking just below water surface, big waves, and reversals (churning current which can hold your raft). Binoculars enhance this step.
Plot the line you will take through the rapid, using your identified points of reference. This will often be the course of the deepest and fastest water. Plot it to avoid the greatest hazards.
Look for bail-out spots, where you can exit the fastest water and pull out to safety if you get into trouble. This should include alternative lines through various parts of the rapid in case of steering errors.
Evaluate the run-out below the rapid for ease in rescue efforts.
Make sure everyone involved knows how to react to emergency situations, including free-floating through the rapid.
Plan to enter the rapid on its smooth V-shaped "tongue." This puts you into its deepest and speediest part.
