Good work love2ski, unfortunately it's really hard to see differences in hull shape from photos. I have used Robs trick of draping cord over the hull at intervals to see the profile changes along the hull.
See how Rob did it to the Atom hull in this review. I copied it in the Flash review. Would be great for reviewers to add this in future.
