I'm not seeing any jogging. The page appears to load normally.
That said, I'm not seeing much content either: just a background image, main banner and a set of menus which don't appear to lead anywhere. In Firefox, the images look OK, but in IE the boat partly obscures the main banner.
I appreciate the site is probably not yet fully developed. As you develop it, you need to check how it looks in all the main browsers, and under Windows as well as the Mac.
