Step hull or Deep- V

You don' t trim in the drives for a turn on a step hull. The benefit is that cruise and top speed is higher than non-step with the same power.

formulafastech.....I think the evaluation has got to go beyond just stating a top speed. Did both boats have the same outdirve, ratio and prop ? Are you comparing a Bravo with a Mirage ? What are the slip factors for both boats ? I think you also have to look at crusing RPM. Props can also have a huge effect on cruise Speed versus RPM. Look at the aricle in Powerboat on the new 5 blade Maximus from Mercury. It produced higher speeds at all but one RPM point and that was WOT.
Point is it's a difficult comparison due to the many variables involved.

formulafastech.....Why do you think they went with the 1.65 ?
ROUGH WATER.... I hear that... Anythime I hear someone running in 12 foot seas, let alone 80, I question their wave measuring or speedo reading capability
