The Pro Sail circuit included the Hobie 21 and Pro Sail Formula 40s. Cool stuff, there were races near shore for spectators, sponsors, TV time. And it died...
I remember watching one of the races that was held on San Francisco Bay. They had miked Tom Blackaller (of A/C fame) who was skippering a F40. It was pretty interesting to watch the cat leaving the camera boats in their dust and hear Tom yelling at his crew.
Tom was also one of the color guys for the humongo New Zealand boat vs. Dennis Connor's cat. In one race the Kiwis got around the weather mark first and then found a hole. They got clear and the cat found the same hole. All the monohull guys on TV said that was the end but Blackaller told them to watch. The cat got clear and beat the Kiwis by minutes.
During the after race press conference one of the cat's crew was asked if they could have beaten the Kiwi's with a Hobie 17. He said no but it was a nudge nudge wink wink kinda moment.
