Charles-
That is it. I thought with the "plumb" bow it would match the Nacra quite nicely and you could simply "scale down" the design to match your hulls/needs.
As for the Taipan- If you visit the F 16HP forum there are at least three Taipan (or Taipan-based F 16HP's) homebuilders that frequent that forum and they can provide you with much information re: costs, etc. I can try to help get you a set of plans if you are interested- They are available (I have a set) and will get sent. Another advantage of building a Taipan is that the class is really getting going and there is now a good market for them here (some folks importing used ones from Aus even!)-
