Looking for pics or more info on Bernardet sidecar

It is a boat-tailed looking sidecar and is featured at

http://bernardet.com/cadre_side.html

Acutally I am looking about for other ideas of a home built boat-like sideacar set up and would appreciate any pics or site info on any. Probably just a pipe dream in playing about in trying to make some rough designs for one, but just toying about with the idea and it seems like a bit of fun.

What would be a fair or reasonable pricing for a complete Ural sidecar chassis with wheel and fender, but no tub? No, I don't need one yet, but just checking on what it may likely cost when and if I ever do.

I have pics for email if the site above does not download ok.
Thanks,
Huey
