Have you read Keith's article from about 1993? It should be in the magazine archive

I was a member but there was not much in the way of model hovercraft i need to know how to get the profiles that would be on the end of each pattern

Hi Ewan
What issue was the article in?
Ive spent ages searching but havent hit the right mag as yet.

Ive been skirting round the theory stuff, and would like to catch up a bit.

The quick reply is two fold ONE the outer cross section of a bag skirt between the top attachment and the contact point is half a circle the inner half from contact point to inner attachment is a segment from a larger circle this radius will vary for all sorts of reasons but if you work on a gentle curve you wont go far wrong
TWO invert model and make a solid skirt from a foam block till you are happy with the shape and then drape material over this shape and sow .

How big should the sow be? Should she be greased?
