I don't use data bases, don't use aku or any other shaping program, don't use cnc, etc etc. I'm as low-tech as they come, drawing my boards on graph paper and buildng them mostly stick by stick from scraps of wood in my little 9 x 14 shack in my backyard. So I don't have a need for any such data base.
But I don't see any ideological objection to such a data base - if anything, I think it would be healthy and helpful to bring the subject of rocker variations out of the closet and into the light of day, as it were.
Swaylocks is mostly a do-it-yourself'er environment of guys who build boards the hard way, sharing info and encouragement to help one another - and a collection of rocker variations seems fully in line with that concept. Its been said repeatedly that rocker in itself is no magic fairy dust, just another factor in the overall equation, so I don't see it as a monumental shift in any particular direction anyway.
The industry is going to go where it goes, and do what it does, regardless of what we here at swaylocks do. It has already shown the direction it wants to go, i.e. computerized designs built by computer-numeric machines and glassed / finished at third-world-labor prices, imported and heavily advertised / promoted to the masses.
For backyarders to share data is IMO actually a bulwark against the industry computerized mechanization taking over the whole shebang - the better boards that we garage hacks can build, the more interest and legitimacy we gain, and the more fun we have!
Maybe its just me, but I just don't see crowded surf, or any other real problems, resulting from home builders sharing info. Heck, even industry pro's are publishing things like templates, board dimensions, volume, design rationale, and fin placement info on the internet.
