We just asked for a price per minute. I could buy quite a nice boat with the amount they quoted.
Unfortunately - I should have said this - it has to be a model of a real prototype, or at least a recogniseable type. I'm writing stuff on the use of models in fluid dynamics.
Froude number vs Reynolds number. Irreconcilable, so models will always look s**t.
If we're going to get technical, it's best to match the Froude number, because then the bow wave looks OK. However, if you do that the time ratio is wrong (it takes the model too little time to cover one length) so you have to film it fast and slow down. It still won't be great, but it's better than they used to manage. The other issue is getting frequencies of roll and pitch oscillation right. That's a further complication which I am skirting round because it's not fluids!
Thanks - I'll check the price of that.
The film went so far over budget that Lew Grade is supposed to have complained that "it would have been cheaper to lower the Atlantic".
