As a hypothetical exercise I am thinking the young one falls off the boat on the first big hit on the right run at Lava. You the parent processes what is going on and identify that everyone else aboard is safe and you then prepare to dive in after junior. At this point you are either abandoning the oars or leaving the oarsman with a redoubled emergency with which to deal. In that split second, on some of the fastest water on the planet, the rapid is over and junior has just had a big swim, ready to be picked up in the eddy below. That scenario does not work at all! There is not one circumstance I can think of where leaving the stable rescue platform equipped with a means of propulsion, extra hands and eyes to help, and all the rescue gear right there at your fingertips is an advantage. Being a parent who boats with family, that boat is the only place to start a rescue effort. Jumping in after someone only makes the situation worse. Training and practice can teach someone how to save themselves and make a rescue effort easier on everyone. The great thing is, the practice and training is FUN and the whole family can have a blast while taking on a serious responsibility.
