The Zodiac Hurricane had a compressor in the engine bay that inflated/deflated the tubes at the touch of a button! Tubes were also bolt on as well as the Arctic and the Pac obviously.
The zodiac had to be the most awesome rib I have ever seen and I was one of the lucky few who blagged a go in it! 11 metres (I think), twin 450hp diesels, surface drives, 60 knots! It's the only one built so far and already sold (can't remember who to) for £500,000
Halmatic were there with the new Pac 24. This ones all carbon fibre making it quicker than a twin 250 o/b Arctic! Cant see these ones turning up for peanuts in a gov. auction any time soon, £400,000 new!
