At the risk of sounding negative... I expect there aren't many companies who would want to to take on the headache of organising that kind of thing. 'Hello Mr Insurer, I'd like to hire out expensive equipment that has many things that can go wrong; to anyone with a basic qualification that they might have completed in something very different; and also take on responsibility for showing a group of them around at high speed'
They'd have to charge a prohibitive amount just to cover the cost of anything going wrong, including bad weather cancellations.
Although if similar things exist for both sailing and motorcycling maybe it's just that no one has done it yet, and I'm being far too cynical ?!
