Here's a draft version, edited as a generalized questionnaire. It's unformatted, so can be copied from here, or I can supply it as a file in most formats. Any feedback welcome!

JRA SAILPLAN PROJECT
The primary purpose of this project is to update and expand the >> Junk Information>Sailplans>Current and Early << sections of the JRA site. Secondarily, the information gathered, assembled and refined will help toward the JRA UPDATE PJR (Practical Junk Rig) PROJECT.
The following have been suggested as useful information to be assembled for each major sailplan:
* Representative photo -- Preferably profile shot from batten side (showing parrels), close-hauled and normalized to view from s'brd.
* Generalized line plan -- Standard and scaleable with spar angles, showing typical control lines and keyed explanation of features, along with a plan of the furled bundle.
* Brief history -- Include the developer(s), notable boats who've used the sailplan, it's goals (e.g., improved windward ability), what was introduced to achieve them, and some indication as to its current popularity.
* Points list of pros and cons -- Such common considerations as cost, complexity, ease-of-construction and -handling, sail set, windward efficiency, tendency to foul, etc..
* Owner consensus -- Generally, does it work as intended? Is it favored by owners? Do owners tend to stick with the type or move on?
* Links to discussion threads, calculators, articles, photos, etc.
* Dedicated Forum for suggestions and feedback on presentation.
Additionally, the following have been suggested for similar presentation as modular approaches, which can be applied to, or modify, more or less any Sailplan:
* Yard angle.
* Batten Rise.
* Rectangular vs triangular panels.
* Flat-cut panels.
* Shaped-panel camber.
* Fanned sail, twist-induced camber.
* Convex luff curve.
* Gurney flaps.
* Roping.
* Stiff spars.
* Bendy spars.
* Mechanical spars (e.g., hinged battens).
QUESTIONNAIRE:
* Do you have any additions to the above categories or elements within them?
* Are there sailplans which interest you that are not currently covered at the current JRA Sailplan location?
* Can you help with this project? If so, what do you have in mind?
* If you are experienced with a particular sailplan or approach, would you be willing to work toward its documentation?
* Can you provide or point to specific information or materials for this project?
* Would you be open to conducting research? If so, are you willing to summarize results?
* Would you be open to requests to handle specific tasks?
Hi Dave. Thanks for compiling that list and for placing it here. To some extent the content will of course cross over with what Chris Galliienne is working on and he's already 10,000 words in. I hear he's taking a break from writing to draw the sailplans - he's posted about that separately. However Chris's work is self-contained though I hear will be thrown open for member comment later. Maybe add a question to the above along the lines of 'Would you like to be help CG top and tail his book?' But please clear it with him first. Re the idea of opening a separate forum for this, David has already set up a section of the site for that. We ahave some members wishing we had fewer fora. Might be better to use David's area, get a team together, I'll give them access to it and then work via email with occasional progress reports here.
