Another trip around the sun and Greg has asked me once again to talk about “great ships.”As an older engineer I find it much more difficult to judge greatness in ships. It was much easier when I was young.When I was quite young and living near the Dutch rivers, I thought the greatest ships were Rhine barges with cars on them. I am talking about the inland cargo vessels that ran up and down the Rhine and through the rest of the European canal and river systems. As a six-year-old, I found the the Rhine barges with cars were so much cooler than Rhine barges without cars.
