"Between the designers and sailors Britain has the talent," said Ainslie.
America's Cup explained
First staged in 1851 off the Isle of Wight in England. Won by US yacht America.
Racing is boat-on-boat, called match-racing.
The event begins with a challenger series - the Louis Vuitton Cup - to decide who gets to take on the defender in the America's Cup.
The winner decides the format and venue of the next event. It takes place roughly every 3-5 years but one-off challenges - to do with complicated court proceedings - also occur.
As holders Oracle chose 72ft catamarans with rigid wing sails. Foils were pioneered by New Zealand. The high-speed boats were initially criticised over safety, particularly after Andrew Simpson's death in May, but thrilling racing suggests multihulls could remain for next event, though possibly smaller.
Oracle also brought racing close to the shore and ushered in a new era of TV production with on-screen graphics to help simplify the sport, a development likely to remain.
No British team have won it, but Sir Ben Ainslie has already launched Ben Ainslie Racing with a view to changing that.
"The America's Cup started in 1851 in the UK and we haven't had it back since so it's about time we changed that."
Although the America's Cup was first held in Britain, no British boat has triumphed in the competition's 162-year history.
But four-time Olympic gold medallist, Ainslie, drafted in partway through the competition after New Zealand had won four of the first five races, said the messages of support he had received proved there was interest in the sport in Britain.
"The feedback I've been getting is amazing," added the 36-year-old, the first Briton in 110 years to be on board a winning America's Cup boat.
"In the past the America's Cup has perhaps been a billionaires game, but in the future it will become a commercial reality to go out there and put the sponsors together to have a commercially driven team.
"We need the [financial] support and I hope this event has opened people's eyes to what's possible."
