Thank you for the reply. However, I see your reply as being more about managing the inherent risks of voyaging than quantifying them.
I'm still curious if there is actuarial type data out there. We know that the insurance industry collects data on all sorts of factors, occupations, locations, etc. Perhaps, ocean voyaging is too small an activity for them to bother with?
Still, it would be interesting to know if there is objectice information about our activity. Is the risk within the normal range of activities? Is is slightly higher? Or, even slightly lower?
