Could anyone tell me if you are allowed to use hovercrafts on the non tidal sections of the Thames?
Not a chance. i think you'd probably get arrested and thrown into the tower of london.
Agreed - official speed limit around 5mph - so to comply you'll mostly be subhump, generating spray and waves. Plus you need a licence and I suspect theres no hovercraft category. Much better down the estuary (eg Allhallows one of our sites) where theres lots of hovercraft friendly mud!
Yeah, ask Tom Hyde what happened when he took his F2 out on the Thames at Staines for about 1 minute! Evoked the wrath of just about everybody.
However, I maintain that if he'd done it in a 79dB F35 it would have had a different response.
I have done this several times; however when I enquired for a license the very polite person in india said that there was no way it could happen (also - is it an inboard or an outboard?). We live where the Loddon joins the Thames, so I can take it without the EA seeing, luckily our neighbours are very nice people. If you're going to do it, take it out on a cold day widweek so no one sees/hears.
Whatever happens, DON'T get caught - the fine is somewhere in the £1000s.
