Classic SeaCraft.com logo question.
 

Is there a difference in the angle of the vertical edges of the stepped panels of earlier SeaCraft hulls than those on my '73 SF20?

The logo at the top left corner of the screen shows the vertical edges to be perpendicular to the bottom. The picture of the hull design in the '73 brochure shows the vertical edges of the steps to be perpendicular to the surface of the water.

There is an old thread discussing this somewhere.

Your picture is correct, the logo is not. Has to do with limitations of the program used when the logo was created waaayyyy back when Trayder still owned a SeaCraft. :D

Thanks ... now I know!
