What's the history of the wreck?

Still trying to identify that particular wreck, she's British and WW1 armed steamer. Triple expansion engine. Carrying a general cargo of cement and war supplies. Definitely not on route from the US to Britain judging by her cargo.

67m. You need to control the lift with decent dump valves and a mooring on the wreck. You can see from the video the top of the bag is just on the surface. The bag can be left go once your shallow enough that it can take the expansion without dumping when it hits the surface, if it over expands and speeds up it will fall over on the surface, dump and head back down.You need a bag with at least twice the lift capacity of what you're lifting. Either way it's a dodgy exercise even when everything goes right. If the bag gets away better not get caught in it or be under it on the way back down. Winch and cable is a better idea deep. Leaving a bag off from the bottom and hoping for the best is a good way to lose the bag and what's on it.

We recovered another 120lb billet from the wreckage. We tied a 100lb bag to it and then used a winch crane to get it back to the surface with 1/10th of the original effort. Turns out it was cheap 1080 low carbon steel. Wasn't worth fighting the state for salvage rights.

Is she a war casualty or did she founder? Where's the bow headed and what lane is she in?

She didn't founder there's to much damage, steel ingots are getting a good price, most of the merchant steamers sunk during the wars off the Irish coast were coming from the US with war material and non ferrous metal ( copper and brass) arms. A good all round bag would have a 500kg lift, not to small and is still handy to use on the bottom I'll put up a photo of mine later.

We had a mystery wreck off Saginaw Bay, Lake Huron near the international boundary between the US and Canada. She was far outside the normal lanes and was headed north with a cargo of stone normally headed south towards the metropolises of Detroit, Toronto, etc. We deduced that she was Canadian and headed either toward Chicago or Thunder Bay Ontario. That left us with two candidates and then it was narrowed down by length and age.

Good place to start when dealing with mystery shipwrecks. There's a finite number of steamers sunk in WW1 in your area. It might be a LARGE number, but the list ends somewhere.
