Then there's no longer any advantage to buying a Blade.


What ? Is wider, stiffer, selftacker, better hullshape, more volume (carry heavier crews), more beam clearance, improved sails (larger squaretops), etc not enough for you ? <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

Anyway what is the actual increase in draft (in centimeters) with the new boards in place


I think the new board are 300 mm (30 cm) longer (more draft) then the old ones. Aspect ratio is 4 and not 5 to 5.5 as with the new F18's. I think these new boards are actually a very good compromise. You are not gaining much efficiency in a daggerboard after aspect ratio 4 and with that ratio the draft is not much anyway. So these boards will still be good for singlehanding.

I seem to remember the new boards being 780 mm in wetted length (underneath the keel line). That would actually only make them 230 mm (23 cm) longer then the old ones. Let me check again.

...

Yeah there abouts. Halve of the aspect ratio gain is made by making the daggerboards more narrow.

So the difference in draft (0.55 to 0.78 mtr) is quite small. But the difference in aspect ratio is much larger, 1.85 to 4, and that makes it appear much longer.
