Now for trim tabs. Great for slow planing but will kill fuel economy
doing
so. They create a lot of drag to force the bow down at slower speeds. Of
course you can raise them and get the efficiency back.

I've found the opposite to be true.

Really, JoeTechnician? Please do tell how you think that trim tabs
don't create drag when they are deployed? And, if they are creating
drag, unfortunately, they are also hurting fuel economy.
