I would have to disagree with several statements here
A 30" setback of the engine does not change the center of gravity 30 inches
The amount of buoyancy in the bracket coupled with the weight of the engine / engines also have to balance, thus the "wave cutting part of the deep vee" hull will not be changed. As a matter of fact, the 410 lbs of floatation in the Potter Bracket Eliminates the typical "Stern-Squat" and decreases the running and the at-rest draft by 3" or 4" [img]/images/graemlins/shocked.gif[/img] The boat will be drier ("NO"Spray rails),Decreased Fuel Consumption and increased Top End and Crusing Speeds with the same HP will be realized. No water into the cockpit when backing down, reduced engine noise and reduction of prop ventilation during tight turns will also be noticed [img]/images/graemlins/smile.gif[/img]
On a 20 footer, the bracket will reduce sliding of the hull. You might experience a slight tendency to porpise at a higher speed but trim tabs will correct that problem real fast. The chance of chine walking with a higher HP motor would be reduced. Added weight by a larger fuel tank and/or moving the twin batteries up forward also must be considered.
All these benefits along with the added cockpit space sold me on bracketing my SeaCraft. You can follow along with my transom transformation on another thread. OK I'm off my
