I am so tired of the second guessing over this tragic accident! Sailing in ANY boat is inherently risky-we race on an unpredictable sea, in tiny little boats at the mercy of the elements. We have witnessed and mourned many deaths on many race courses over the years-but I don't recall the kind of hand wringing panic in the past that we are seeing after this sad event. Sailboat racing has always pushed the envelope of what is possible/safe at any given point in history. That is why we now have exciting sport boats, canting keels, bulb keels with ludicrously skinny fins/struts, high tech ultra light materials, foiling moths, tris, etc. And each advance was gained at high risk (and loss) for crews racing on the cutting edge-think about carbon rig failures, bulbs falling off of keels, rudder failures, round the world tri's and mono hulls failing with sometimes catastrophic consequences-just to name a few.
Think also of the IACC boats that failed or sank-in any one of those incidents, a stroke of bad luck could easily have led to a fatality. But no one that I can recall called for the abandonment of the series or replacement of the class, and in fact those boats are now considered slow, boring and too safe.
The normal response after such failures and tragedies as this is for the sailing community to assess what caused the incident, and then adapt safety regulations or construction scantlings as required to address that cause. That is what needs to happen in this case-nothing more, nothing less.
