How to give a HSE Officer a heart attack this Christmas - Giroboat 1961

I think we can safely say that as this sub 50' thing isn't in the ANO it doesn't actually exist. Neither does the ANO say anything about "Anything which ever flies above 50' AGL needs to be registered. "
It does specify registration of flying machines by weight in order to regulate some of the excesses of the model aircraft fraternity but says nothing about registration vs. height - at least, not that I've ever found.

So what says that a homebuilt hovercraft operating at 6" AGL doesn't need a C of A? There's a lot more to the regulation of flying than the ANO, of course.

Shame, really. I quite fancy rocking down the Solent at 200Kts during Cowes Week in a Caspian Seamonster, Blackball pennant flying! That really would bring on some heart-attacks!

Me too, if you want the plans you are welcome to them. I think they have something like a 6ft ceiling. The "wings" are simple fabric affairs. Our mooring is yards from the Griffon Hovercraft factory, and every time we see one of their beasts out on test I think about it again, if only to see their faces as I flew past resplendant in my pith helmet and flying goggles, laughing maniacally as the steam powered contraption I had rigged up as an engine roared and sputtered atlernately, pitching me from a steep climb, to a nose dive to the soundtrack of a doodle bug. as the wife paddled wildly along behind in her copper botton canoe, hanging on desperately to the safety line she had crocheted from old damask curtains , in an attempt to prevent my escape to the world of Icarus himself.
