I did use a cheap CAD program called Turbo Cad to float the engineering lines plan and to have the frames for the mold cut. Other than that, Shuttleworth did all the designing.

Hi Thiago. I bought the plans from an incredibly talented architect. His name is John Shuttleworth. Shuttleworthdesign.com.

Nice! One of the questions I have for you is What Software did you use to build this Cat? What Software did you calculate Stability? Did you have any help with individual Naval Architect person? Before you built the final model, did you do a mini model to run analysis and stability tests? Thanks for your help.

nice second video told me the answer to my previous question. John Shuttleworth is awesome!  

Hi man! What design do you build? Do you have a blog of building process? Regards, -SP
