423 The 423 is a comfortable boat, both at anchor and under sail. Although no longer in production, I think the quality and popularity is evident by the fact that one rarely sees a 423 on the used market.
Ref. the slight list to starboard comment (w/ the genset): Some have towed extra anchor chain under the port settee as a counter balance. There's a good owner's chat link in Yahoo Groups, with a lot of wisdom.
