I've fished as a co in different tourneys for a couple of years now and out fish my boater probably half of the time. I find that as the co-angler, you has a slight advantage over the boater, sure he may get first shot at every point of interest, but you can use his failures to build a succesful pattern before he does. Pay close attention to where the boater places his bait, there will be plenty of spots he will miss and if he is not catching you will be there to place your bait in the #2 spot on that structure or cover. Ex: boater casts to points of laydowns and doent get bit, you cast to the back of the laydown and work through it. Boater casts to shade side of a stump, you hit the sun side, etc. so on and so fourth. The co-angler actually gets to see what doesnt work on a piece of cover or structure before making their cast, the boater is casting blindly until a pattern is determined. Now, if you have a very patient boater that smoothers every twig and branch with casts, then downsize your lure a bit, maybe a little more or less action, and go from there. Good luck in the future!
