Jacob, You answered your own questions.
Yes, you are @ a disadvantage being a back seater as the boat operator acts as a fish vacuum going down a bank leaving you no virgin water. However most "draw tourneys" I fished always split the time on the bow, let's say 4 hrs and 4 hrs. This is fair, he takes you to his fish then you take him to yours. I have gotten my head handed to me back in the day. Remember the old pistol grip rods? I had a set, and fished a draw tourney on lake Seminole where the boat owner had 7 ft rods, full length handle grips and threw a Carolina rig with a 1oz lead. He cast about 50 yards to a sand bar and limited out in about 15 casts with 5 lbers and left me standing there with my short rods and reels and 1/4 oz T-Rigs. Tough lesson to learn but I did and you will.
Keep fishing them I promise it will make you a better fisherman.
