SS Nisbet Grammer

The Nisbet Grammer was a lake freighter that served on the North American Great Lakes from her commissioning in 1923 until her sinking in 1926.
Sinking.
She sank on May 26, 1926, after the "Dalwarnic", a freighter of similar size collided with her.
The "Dalwarnic"s bows pierced one of her holds, but all her crew were rescued.
Both vessels encountered a fog bank on the night of the collision, about , east of the Niagara River.
The "Nisbet Grammer" had reduced her speed to half-speed. Still, the vessels were too close to avoid a collision when they sighted one another in reduced visibility of the fog bank. She sank in fifteen minutes, in of water.
Location.
The exact location of her wreck was unknown for 88 years, until an expedition found it off Somerset, New York. Researchers searched for the wreck for six years. The wreck is the largest steel-hulled shipwreck in Lake Ontario.
