Which is it? Development class, or other?
You can't develop a boat within limitations, and make significant progress. If you want to do that, go race monohulls, and compare silly tweaks ad nauseum. Adding a hull is a no-brainer, but do they do it?
It is pretty embarassing that, in my opinion, the big improvement in sailboats (that have been adopted) since BC are the sail batten, and maybe rotating masts (although still not universal yet). Sorry if this tone seems combative.
