It was a tragedy that apparently America's Cup authorities did not see coming.
Artemis' catastrophic training accident which led to the death of British sailor Andrew Simpson was "not on the radar for any of us", according to regatta director Iain Murray - the man tasked with leading a review into the incident.
What caused the Artemis boat to flip while performing a bear-away manoeuvre may remain unknown for the moment - although early indications suggest a major structural failing - but the path they travelled to get to this point is quite apparent to most.
From the outset, the giant, hi-tech catamarans were a massive over-reach in time, cost, and complexity for the competitors - Sir Russell Coutts admitted as much in an interview with the Herald last year.
The AC72 is a workable class, albeit horrifically expensive, if the design is well thought-out, the construction sound and it is sailed under sensible conditions. The boats may be on-the-edge, but they are appropriate for high-level competition. The fatal flaw in the planning of Coutts and his cohorts was not in the design concept, but the timing of the regatta, which left teams with little chance to get their heads around the new class.
