I have been reading thru this thread with much interest- Having been planning on building a Cat for a few years- Started lofting out some ideas last night. It seems the common thread here is Tri's- I am a cat man thru and thru- Pics below is my day job- 70ft long and very fast.

So I want to build around a 1.2 mt cat and really like what I see Multiman doing so can any one out there provide me with some basic cat guidelines based on 1.2mt LOA- even better has anyone got plans for a cat that will perform without all the usual design flaws??, any help much appreciated /) /)...
