For those that aren’t challenged enough by buying a fully working hovercraft… the ebay advert below may be of interest. 

You’ll need access to some tools of course…. a strimmer, shears – possibly a JCB. But once swept up, fixed up with a new hull, new engine, new fan assembly, transmission, skirt and steering, ‘Triggers Broom’ will be a fine hovercraft.

And do remember, this bargain is a BOGOF (Buy One Get One Free) as there’s a second craft included with this one free of charge (though the vendor does say it’s one worse condition than the one pictured.)
