Reducing the upper web page margin

I am new to web design.  I would like the layout of my web page to show a page title, an image, and a menu above the fold.  And I would like this to be reasonably consistent across commonly-used screen resolutions.  However, I also would like the image to be as large as possible, to preserve the impact.  Please look at www.mauitradewinds.com  and let me know if there is a way to eliminate what appears to be wasted space at the upper margin.  The page title, which is also an image, is 40px high.  But it appears that there is another 60px of empty space above that title image, and perhaps some unnecessary space below it.
