Hello Alumcat,
I see from some of your posts/comment that you built a tim mumby Cyber ( 48 feet alu cat). I am seriously thinking of embarking in the same project in Italy so here I am asking a few things. ( I haven't bought the plans yet)
How detailed where the plans? were there enough instructions for an amateur to complete the build? What was the running cost at the end of the project?
I was considering scaling down all the plans 10% to make a 43 feet version of it. Do you think this is achievable considering the amount of information included in the design?

I have an engineering background to put things in context, but of course I believe this would be a massive undertaking.. Any info that you wish to share at this point would be highly appreciated!

Stefano
