Faster makes a good point about mast rake. Too much rake could induce excessive weather helm. That's something worth checking. But there are a lot of other factors that come into play in the overall design -- it might be worth researching to see if this particular design has a reputation for exessive weather helm. Just tossing out possibilities -- it may have nothing to do with the sails or rig, it could be e.g. that the rudder is not adequately sized.

I have seen mainsails on cruising boats where the (short-handed) owners went to a negative roach and eliminated battens. The idea as explained to me was to deliberately depower the main a bit, to thereby postpone the point when a reef bacame necessary, and to eliminate a source of chafe on the sails for long-distance voyaging. But with the advent of full-batten mainsails systems even for cruising boats, I haven't seen that done much anymore.

Hopefully JeffH or some of the other knowledgeable designers here can offer additional insight.
