I have a 25 foot boat, with a single-stepped hull, 24 degrees of deadrise at the transom, and terrible weight distribution due to the big block engine option. It's obviously a pretty bad combination for slow speed planing, but it'll easily plane out at 19 MPH with the tabs down, and 24 MPH (speeds measured with GPS, not the OEM speedometer) with the tabs retracted. I have a Bravo 3 drive, so I suppose that helps a lot, but I find it hard to believe there's many boats out there that really won't plane at 25 MPH.

Mine does get substantially better gas mileage from 28 MPH to 40 MPH compared to 25 MPH though (as measured with a Lowrance LMF-200). Literally, 40% better.
