Agree having sail area down low is not ideal, but we have a problem of low aspect ratio sail area creating boat handling and design problems as a solo, so putting 1 - 1.5sqm down low ( think more windsurfer sail shape )generates a bit of power and keeps everyone happy that they still have 15sqm of sail on a 8.5 class legal mast with a higher aspect ratio not unsimilar to the A Class.
