You're on the right track set up a person out the back, we do it all the time, if the waters deep you want have to much of an issue. Only time I don't like to have someone fishing out the back is when we're fishing ledge's were the water comes up quickly, or shallow water cause the person in the back usually wont catch much, (I'm calling less that 10' of water shallow). Have fun and keep taking them fishing as much as you can.
