Extending the hull almost 50 ft would certainly improve bouyancy and ride. Considerably. I've never sailed on Lake Superior, took the car ferry round trip, Kewaunee, to Ludington and back, (Lake Michigan) years ago. Been all over the Pacific several times. Love the North and South Shore of Lake Superior.

Cohunt, the R/V Kiyi is a good looking vessel and still roams around here quite often. Last year she spent a lot of time up around White fish point.

Just looked up this ship, I've seen a ship like this run in and out of Ashland, WI.

Home base for the Kiyi is at Ashland WI. The US Govt Lake Superior Research Laboratory is also based there.

Very interesting Cohunt, what types of research were you involved in on Superior?

Interesting. Is this agency within the Dept of Interior ?

May have been this ship I’m not sure but I saw one like it up close this summer fishing out of Silver Bay on Minnesotas north shore. Terrific idea having a pocketed pusher at the rear that could detach.

On some units it’s a good idea Osky…… not so much in this case. That tug is not very useful without the barge

To questions about the KIYI and etc. The R/V KIYI and the Lake Superior Research Laboratory are units of the Great lakes Science Center located in Ann Arbor MI. There have been several name changes for the Science Center over the past 60+ years but during the time I was a research scientist there it was a Dept Interior laboratory of the US Fish and Wildlife Service. When Clinton-Gore came into office they relocated it into the US Geological Survey which led to my early retirement. My personal research on Lake Superior began in 1970 as a Limnologist who is a person that studies fresh water and the things that live in it. Over the years I did more and more work with mathematical fisheries biology to help clarify the sea lamprey-lake trout interactions and to produce the results needed to advise the states and tribes about the quantities of lake trout in the various political jurisdictions of the US waters of the lake(3 states border Lake Superior and each state has one or more tribal units who eventually claimed commercial fishing rights). I have published about 50 scientific papers in refereed scientific journals including the most recent which is just about to be published as well as about 10 more in journals of the Siberian Academy of Science done in collaboration with Siberian scientists on lake Baikal.

I'm retired USDA-NRCS. The Ashland Field Office was one of sixteen FO's I covered. The USFWS has a pretty big office there. USGS also has an office in Ashland as one of our Soil Scientists moved over to USGS after I retired.

That ship is 2.41 acres. That's impressive!

Keith: Just for fun calculate how many semi trailers would it take to haul 57,500 TONS of cargo.

2054 C-130 Hercules.....depending on the distance

I of course know there are bigger boats than my 33’er but when that tanker came in close “dwarfed” wasn’t anywhere near a big enough word. I was amazed at how agile it was and how fast the skipper brought it in behind the break to loading position. I believe they told me 10 hrs or less to load her full of ore.

Thank you.

Osky, those large vessels do not respond well to the rudder in tight or short distances. Instead they rely on transversly positioned bow and stern thrusters.Those thrusters are large props in a tube through the sides of the ship, and are powered by big GE electric motors. Forward or reversing them gives port/starboard movement, forward and aft. That is what makes them highly maneuverable in tight/ short distances.Very impressive watching them move like that.

Thanks for that explanation. I knew they had thrusters in front but I’d never really thought about the mechanics of them. Crazy cool how creative and industrious people can be.

Great thread! To The Top!

That's the same square footage as 233, 53' semi trailers.

dang good read guys
