does anyone know the reasoning behind the current trend of dreadnaught bows?  is it a way of getting round rules?  I'd have thought that it would reduce the volume forward and make pitchpoling easier.

As far as know it is all down to reducing "wave making"  charactistics of the hulls and thus reducing drag and thus increasing speed. 

 

I've never sailed an A; but if you look at pictures of current boats the rig is fairly far back on the boat so I would guess the pitch-poling tendancies are not too great.

Never heard of "dreadnaught bows" what is this ment to mean ?????

The current trend in cat bows are to reduce the hight of the bows (less windage) with plenty of volume down low whislt not much up high.  King of like the shape of a pair if you look at a cross section.  This allows water to flow off the top of the hulls easier if the bows are submerged.  "Wave peircing" bows

the phrase comes from WW2 (I think) where the dreadnaught class ships in the german navy had bows where the the foremost point of the vessel was at the base of the bow instead of having the deck level sticking out over the front of the waterline.
