Being a yachtie myself...
And living not too far away I've also been round the HQ, and have also had the pleasure of seeing them zoom around on the Solent at very close quarters whilst I've been out sailing on my low tech floating tub. The yachts (if you can call them that) are pretty incredible and they fizzzzzzz through the water - as is the tech used now in race and performance management.
It's just a shame then that the racing itelf (as a spectator sport) is as dull as a dead lighbulb; and that Portsmouth City council - total fucktards that they are, and despite representing a city with a proud, noble and very lengthy marine heritage have decided to try to use the presence of the Americas Cup to fleece as much cash out of the locals and vistitors as possible, with very little service or benefit by return due to their total fuckwittery at financial management.
Biting the hand that feeds IT
