This page is dedicated to the Universal Hovercraft UH-12R that I built in my garage way back in 1995. It all started when I purchased Universal Hovercraft's catalog for $2 August 20, 1995. I then decided on and purchased the plans for the UH-12R shortly thereafter and started contsruction in early March of 1997 and put $40 into the project every two weeks.

|This is a partial scan of the 12R plans and only shows the side view. The full sized plans show a top view, a front view, and a side view as well as rib layouts on the first sheet and a second sheet containing details on mechanical structures. I've run into some ambiguity on the plans regarding the layout/shape of the lift duct, the location of the skirt attach strips, and the attachment of the rib 1 at the front of the craft. In my opinion, the plans need to show more detail of the front of the craft.|
