Well, Arild, first of all my statement was that on LAKE SUPERIOR one can count the number of SHIPWRECKS on one's hand in the past 50 years or so. And I think that statement stands. That number obviously does not include the rest of the Great Lakes or boating/shipping in general elsewhere. But there is a greater point and that is going to sea is by its very nature inherently risky. I will accept all the aids to navigation electronic or otherwise that I can afford or fit on my boat. Is it fool proof? No. As I pointed out in a post a week or two ago, we watched a professional commercial pilot run his ship aground in dense fog using his radar and mis-interpreting the data. Though accidents still happen in boating and shipping inspite of modern aids to navigation, the mortality rate for seamen (both recreational and commercial) is tiny compared to a century ago. Our own region is rife with endless tales of seamen who perished in relatively local waters a century ago. Do we have better vessels today, no doubt. But I still maintain that electronic nav aides, though not fail safe or fool proof, have dramatically reduced the perils of the sea. And in our own region, my radar is on everytime the boat leaves the dock.
