I checked the settings of one EU Blade F16 just now. Using the method describe with top of deck variation, it touched the rear egde of the inspection hatch. It still looks like a considerable amount of rake but less then yours. Boat felt well balanced to me when I sailed it and the owners are getting faster and faster..

My own boat (modified Taipan) has now very little mast rake. The mast is almost straight up, I'm well ahead of the rearbeam when measuring. Uni-rigged it handles very well that way. I changed it at the beginning of this season. Haven't done to much sloop sailing yet this season and it may be a little too much forward for that. But I will know after this weekend I guess.
