You are so wrong at so many levels Clean.
First, there have been and will be way way more than 250 sailors in 2 editions. Remember that many only sail one or two of ten or so legs and there are probably ten per boat each leg and ten legs or so.
Second, VOR has had a preventable grounding, a yacht sink in the middle of the Atlantic, lost people overboard and people die (RIP Hans). The navigator on Scallywag got hit in the head by the boom (the cause of death of one Clipper sailor last time). All of those were boats full of pros.
Clipper goes on these races every couple of years (ie more frequently than VOR). They do an hell of a lot of work on safety and they take average people who still sign up having assessed the risks and the history. Sure there should probably be more professionals aboard but how many is the right number.
In any event now is not an appropriate time to have this discussion. Let his family grieve.
