Holy flying catfish! Making an exception to strict house rules by turning on the telly in daylight for the first time since the Twin Towers disaster, to watch America's Cup racing last Sunday morning, proved just how dangerous daytime television can be.
As the Team NZ boat reared up and hung suspended in mid air, time held its breath while the world balanced on a wingtip. Momentarily the picture was unfathomable. It could not have been more disorientating had a Vogon Constructor Ship hoved into view.
Even after the horizontals and verticals regrouped, the palpitations subsided, the boat resumed sleek uprightness, and the telly was safely off, everyday reality remained electrified by an undercurrent of potential that any minute the world might flip again.
The ideal way to sail is gently, in light airs with a capable captain and nimble crew in a well-stocked, impeccably maintained, classic wooden boat, preferably with a sturdy boarding ladder, in warm waters. But even so, venturing forth must be in the full understanding that anything can happen at sea. Dallying with the powers of Tangaroa and Tawhirimatea is inherently risky - which is probably what makes it so exhilarating.
Despite recent calls for tightened regulations around wearing lifejackets - by deluded safety crusaders who counterproductively attempt to shackle our every move in these obsessively risk-averse times in the mistaken belief that safety is anything more than a fond illusion - America's Cup crews do not appear to wear them.
