lets see if I can answer some things
Lake Erie does freeze over the fastest because it is the shallowest. The western basin freezes over every year. Along the shoreline it freezes over. Sometimes it can freeze over near the shore, and then be gone the next day, if the ice doesn't have time to build up. In the past, it depended on how big the ship was, if it was pulled up or not. Most just tied up in rivers, like the Cuyahoga, Ashtabula, Huron, or Rocky River (I saw pictures as a lot of water sided restaurants have them up for viewing.)The main problem then was the thaw in the Spring, when Ice Jams form. They make a dam and everything backs up. They use to use anything from howitzers to dynamite to CG Icebreakers to break up the jam. And when it goes, nothing, and I mean nothing, stops it. I've seen whole docks, restaurants, cars, you name it, going by. It really is a sight to see. As for the sinking...a few years ago a tall ship came in to Cleveland for the Tall Ship Festival. At the bow, on the dock, was most of the upper forward mast (top gallant maybe?). It was about 50 feet long and 2'to 3' in diameter. HUGE. We asked the Captain what happened and he said this. "I came in from the St. Laurance. I heard of stories of the Great Lakes and Lake Erie, but paid little attention to them, thinking they were myths (same happened in the Chicago to Macinac race with Dennisw Conners a few years ago). I knew nothing of Lake Erie and so assumed it was like the ocean. We sailed a few miles into the lake knowing there was a storm coming. It appeared to me to be less intense than an ocean storm, so I discounted it. We had all but the top sail up and it hit us broadside. Blew out several of the mains in a heartbeat, and the three sails on the bowsprit were toast. And we heard this crack from above and saw what you see on the dock hanging on by the lines and acting as a battering ram was tearing up the rest of the front rigging. In the process of the first winds to hit, we healed over so much that the port rail was completely underwater. I never, ever, saw a boat do that on the ocean in my 11 years as Captain. I ordered everyone to get life jackets on NOW, and for all but a selected few to stay below. We came within a few degrees of going turtle, which would have sunk us in minutes. NOW I know what the stories were about and have a new respect for anyone who sails on this lake."I asked them why he had them stay below and he said it was too dangerous with the rigging being destroyed, and most of the crew was high school or college kids, and most of them were puking anyway and useless. Better to have them below and out of the way. It was a tossup, and I was scared to death to make the wrong decision."We actually prefer the lakes to freeze up. Why? It keeps the water from evaporating and allows it to build up in height, which means the 600 and 700 footers can carry more cargo at the same cost, which increases profits and lowers our costs. It also stops the notorious Lake Effect snow machine. See, the water evaporates and the moisture heavy air blows over the land and when it hits the high elevations it falls. Last year on this date in Chagrin (just east of Cleveland) they had 44" of snow in one falling, 48" for the day (which set a record) and 60"+ for the storm. Yes it caved in roofs till people shoveled them off. There are only three places on Earth that get Lake Effect snow, and Lake Erie is one of them. So the next time you see Buffalo getting 20"+ you know why. Cool things. On a still winter night, with the lake frozen in spots or all over, you can walk on the ice (they drive cars on it to ice fish on the Western Basin. The ice gets several inches thick. I think 4 inches it the limit for cars to safely go over it.) The ice is a live thing. It moves, shifts, cracks, and in the stillness, you can hear it. Spooky. Maybe thats why they call it Lake Eerie.We scrape the snow off the ice at the marina and look for lost stuff from the summer that dropped overboard. The water settles and gets clear and you can see the bottom at 8'. We have read the labels on beer bottles. If we find something retrievable, we bore a hole using a post hole digger, or just chip it out, then try to retrieve the object. The ice builds up these huge walls of ice as the winds push the flows to more solid, unmoveable ice or the shoreline. There is name for these mountains of ice and they can be near shore or out there miles from shore. In the spring, if you are careful you can motor or sail through these leftover "icebergs" and see how far down they go. Very cool, but dangerous. Lastly, look up DURECHO. We have them a lot here. They are sideways tornadoes and can occur year round. In 1911 they had one in November that sunk something like 100 ships on the Great Lakes. Winds are as high as hurricane force, only for some reason they don't call them hurricanes. There is a book out on one called "White Storm" or "White Squall" subtitled "the storm of the century." I saw the one on July 4th. It killed three people and sunk a lot of boats and shut down Cleveland for days because of the thousands of fallen trees. ANd Toledo got it worse then we did!! People were running their powerboats onto the shore, where ever they found it (Lake Erie is mostly cliffs up to 80' high. Hardly anyone has sand beaches because they wash away so fast. A few years ago they imported sand from Minnesota, tons and tons of it, to restore the beach after just one bad winder took it from 100 feet to about 10. The next year, most of the new stuff was gone too.
