I'm not allowed to get into the hull volume and T-foil debate so I won't. However I can tell you that the rearbeam is definately not too low on the Blade (any version). I have sailed the boat in pretty severe wave and chop conditions with my 90 kg on board together with the 70 kg owner and at 160 kg the rearbeam stayed clear of the waves. That is all you want (need) really, so it passed the test there.
