He also scored points earlier by refusing to blame the absence of banned wing trimmer Dirk de Ridder for the defeats in the first two races, nor a slightly damaged wingsail and he admitted Oracle were being beaten by the Kiwis in tacking.
JS: "We want to keep the Cup here in the Bay. These guys don't. They want to take it to New Zealand, which is a long way away. We want all the people of San Francisco to get behind us; it makes a big difference and gives us a competitive advantage."
DB: (with wicked grin) "If we take it to New Zealand, you can just buy a new house down there [Spithill has an American wife and kids and lives in San Diego]."
JS, asked whether tactician John Kostecki would be on the boat for Race 6 after some questionable tactics yesterday: "You can be a rooster one day and a feather duster the next, mate ... I don't even know whether I'm going to be on the boat."
DB, asked whether he'd replace the tactician after a race like Oracle's yesterday: "Oh, I don't think you can blame any one person. It's a team thing."
JS (on preview video, before America's Cup racing began): "I wouldn't say we're particularly close; he comes from a more privileged background whereas I had to fight and earn almost every single thing I have today."
DB (same video): "We know they are a very strong team, he's got a very strong group of guys around him - there's no doubt they will be formidable opponents."
JS (same video, released before the match but after the ACWS cheating saga): "For the past couple of years we have been match racing each other in multi-hulls; he hasn't beaten us once when we've faced each other head to head." ETNZ won the first two America's Cup races and now lead 4-1 after five races, 4-0 on the official scoreboard.
DB (same video): "We know each other well, have raced each other in the America's Cup World series, and there was mixed results there between both teams."
JS, asked a wonderfully theatrical, made-for-TV question about two minutes long from CNN's Richard Simmonds about whether he was sailing aggressively: "These boats are either full throttle or nothing. It's like trying to park a car with the accelerator down."
DB grins when asked by the same reporter whether Spithill was the more aggressive sailor: "Whatever you say, Richard." Laughter.
