Design Note
I am happy I went with the tilt trailer design and have now got it to a point where I can load the craft on and off without much assistance. Because the aluminium sides are the way they are, the craft upon loading self-centres itself.
Something I noticed is that by the time the hovercraft is halfway up the trailer, the skirts are pressed against the side panels and create such a good seal that the air has nowhere to go, making the craft tilt dramatically to one side. To help the air escape I drilled several 40mm diameter holes in the rear section of the side panels. There is about 3 inches clearance either side to the trailer sides, but the skirts fully inflated are also around 3 inches, so it makes for a snug fit.
