" REPLY: As a rule, we don't plan to head out in fog on purpose, though I must admit we have done so on a variety of occasions. However, there have been times on Lake Superior when a fog bank descended on us very quickly and suddenly we could not see beyond the bow of the boat. It is VERY disorienting. I have witnessed 700 foot ships go aground in the Duluth harbor in fog. Though they had radar, GPS, and the best of commercial electronics, fog is very disorienting. In the situation, above, the pilot misinterpreted a side channel marker on his radar as the mid-channel fairway buoy. In steering to the left of the buoy, thinking it was the mid-channel marker, he ran hard aground and it took a fleet of tugboats several days to pull him loose. Fog is disorienting. Radar is helpful, but this professional pilot nevertheless ran his ship aground even with radar. David Sorenson Duluth ____________________________________________________________ All is not lost!
