It's the latest design rage - "Wave Piercing". The idea is that you go through the chop instead of hobby-horsing over it. I think the result of many of the recent designs that have the reverse raked bows do some wave piercing but it's a bit more complicated than simply punching through. I don't think the angle of the bow really plays much of a role in this effect either - but it's a sexy look. It's about where the hull volume is placed vertically and longitudinally resulting in a boat that is 'tuned' to a certain frequency chop such that it bobs over one wave and punches through the next. This results in half the hobby-horsing...i.e. a smoother ride and less 'tomahawking' of the rig while not spending quite so much time with a lot of hull under a wave. It's a difficult concept to design without making the boat very pitchpole prone - but some seem to have accomplished that.
