Bob's principle - adjust the trim up or down on the motor and trim tabs so the boat rides the way you want, then sit back listen to some tunes and enjoy a beverage of your choice as long as it is legal and nobody else gets hurt.
Doc, thanks for the physics lesson. I vaguely recall this stuff from my college days. You are not a bad physiscist for a biologist (lol)....
I find trimming the motor up, not all the way up, seems to keep my 22 footer tracking well in those no speed zones. I have never messed with the tabs. Maybe I will erxperiment next time.
