It sounds nigh on unbelievable but, almost on the eve of the America's Cup match between Oracle Team USA and Emirates Team New Zealand, the two Kiwi principals - Sir Russell Coutts and Grant Dalton - have never spoken to each other.
Not in any meaningful, one-on-one conversation, anyway. That strange fact, highlighting the sometimes bitter rivalry of the America's Cup, underscores the sailing which will start on Sunday (NZ time).
Each has more than 30 years of sailing experience. They have come down very different sailing paths - Dalton through round-the-world yacht racing; Coutts through Olympic dinghy sailing and then into the America's Cup.
"We don't know each other at all," says Dalton. "There must have been a few pleasantries expressed along the way but that's about it. I guess I must have sat around a table with him and with other people at meetings, but only once or twice.
"We come from completely different worlds. He's a dinghy sailor and I'm a round-the-world racer."
