Cat / Tri dis-planing / wave piecing hull design

[llamalookout]

Has anyone seen example hull profile / cross sections on the web for the new style of hull we see on racing cats & tris? This type has a very sharp vertical wave piecing bow which slowly tapers back to full width around midships. From here the underside of the hull tapers up to the stern for a semi-planing rear.

An example is B&Q sailed by Ellen MacArthur:

Do you actually wan't accurate cross sections through the main hull at set points along the length? I don't know if such a thing exists on the web. What is the purpose, in other words please explain what you are wanting to do?
It would not be difficult to draw up an approxiamation of the lines from the numerous photos in sailing magazines showing the main hull flying. :cool:
