That's one reason I've pretty much given up fishing the pro-am format. For starters, my strength is fishing shallow, knowing my targets and fishing them carefully and thoroughly. I like to cover a lot of water and when fishing alone, I keep the boat pretty close to the bank. I've had to do that in pro-am tournaments in the past and never did extremely well because I felt like a heel for keeping my back-seater cut off all day.
I like for the person with me to catch fish, even in derbies, which was pretty evident a few years back when my partner won the co-angler division of that year's BFL stop on Table Rock. I probably could've caught a few more myself if I hadn't been generous enough to let him have more than his fair shot at the fish. But this guy was new to tournament fishing and I wanted him to have a good day. And did he ever.
Not patting myself on the back at all. Just saying, pro-am events can be a bad deal for both the boater and non-boater, provided the boater has enough of a conscience to feel bad about pigeon-holing his partner all day.
