J-14 Iceboat Plans

Anyone know wher I can obtain a set of construction plans for a J-14 iceboat? I recently saw some stuff on this design and really got interested, but I can't seem to find any source for the plans.

Yahoo! (Iceboating)

I believe the Yahoo! Iceboating group's "Files" area has a pretty complete set of plans/photos:
