On swift, rocky rivers, you seldom have a moments rest between slowing the boat and maneuvering. Wearing light gloves can help to avoid blisters. The faster the water, the sooner the set up must be to avoid obstacles. It is very easy to underestimate the power of rapidly flowing water, which can be dangerous. In addition to dodging boulders, there are several other situations which you will encounter.
River velocity is generally greater on the outside of a bend, where the current often accelerates.
Rocks and downed trees are often also lodged on the outside of a bend. Upon entering a bend, plan in advance to back away from the outside of the bend, aiming your stern toward the inside corner, ready to power away from the outside bank. Set the boat up before you enter the situation. The more swift the current, the more power you should be ready to apply. Have long length of rope on hand to tie the boat up or to yard the boat through the rapids from shore.
