September 9, 1901. While seeking shelter from a storm, the two masted schooner Sea Gem
ran aground south of the Manitowoc harbor pier. Bound for Milwaukee with a cargo of 100 cords of wood slabs, the schooner had been attempting to enter Manitowoc harbor under staysail, when she barely avoided colliding with the south pier. The anchor was then released, but it failed to hold and the schooner was driven onto the beach, where she soon went to pieces. All five on board managed to jump onto the pier and a portion of the cargo of slabs was saved. The Sea Gem
was en route from Charlevoix to Milwaukee when the wreck occurred. She was not insured so the loss of about $1,500 was total for Captain Hanshaw
