Personally I find Nick's site far more interesting that mine !
My site deliberately does not contain any plans or designs as they are the property of their designers, and royalties need to be paid to the designer for each hull. Key numbers are deliberately omitted, as are laminate schedules as I don't want people getting themselves in trouble.
If you are dead set on building, I would recommend that you contact a local builder and buy a hull shell, deck and frames, and then progress from there.
However I have to echo the advice of Phil above, that if you are building as a way to get a boat cheaper, than that is the wrong reason to do it. I built my own boat in the period when foilers were in very short supply (before Bladerider existed). It has taken 5 ish years of developing that boat to get it to have reasonable pace, and most of that development was progressively swapping out home built parts with professionally made ones.
Now, that doesn't mean that home designed, and home built can't be faster, however even most "home designed" stuff is now being professionally built, to get access to commercial grade CNC, or 3D printing etc.
You can get a second hand prowler for $5K now, and you will never build for that price.
