Maybe not everybody have the skill (or is stupid enough) to want to experiment with their first cat.
That does not mean that they don’t have the skill needed to build one. Both are beginners no?
Lets face it, there is a lot about building the hulls, a lot of descriptions and very few drawings but for the rest... you are supposed to know what it looks like and were and how to fix it.
If I compare to the plans of the 6.50 there is about 40 sheets of computer drawings (a CD with all the files to have the plywood cut and the rudders shaped by computerised machines) and one paper with text. Ok, they cost 7 times more.
Still I like the plans for the Blade, maybe because the best things I have made has always come out of drawings made on the floor in the workshop.
