Grandpa Whitey lives on Madeline Island on Lake Superior and loves ships. He told me about the Marine Traffic app for identifying and getting info on ocean-going or Great Lakes ships. From our condo, we see all kinds of ships: barges pulled by tugs, submarines, cruise ships, Coast Guard, whale watch and tour boats, etc. I have been having a blast identifying the ships. For example, I saw the cruise ship pictured above going past our island; I’d been watching for it as friends of mine were aboard and we were hoping to meet up on Maui. But the ocean was too rough for them to stop so the captain made the decision to cruise around, hoping conditions would change and they could tender people to the island (but sadly, they never could). For $4.99, this is a lot of fun (and it gives much more info than I’m showing)!
