Gallinipper was a schooner that sank in Lake Michigan off the coast of Centerville, Manitowoc County, Wisconsin, United States.

[2][3] Nancy Dousman also carried employees of the American Fur Company and other passengers, including immigrants who settled the Wisconsin Territory's frontier.

[3] The schooner Convoy later made an unsuccessful attempt to take her under tow 10 nautical miles (19 km; 12 mi) from Manitowoc, but gave up and abandoned her 10 nautical miles (19 km; 12 mi) southeast by east of Manitowoc after salvaging her mainsail, main boom, and main gaff.

[2] The wreck lies off Centerville in the waters of Manitowoc County, Wisconsin, 9.5 miles (15.3 km) east of Hika Bay Park.

[3] The standing rigging has been damaged by fishing nets snagging on it and efforts by fishermen to free the nets, resulting in the mainmast being pulled from the mast step and toppling forward so that it rests at an angle over the bow, the foremast breaking loose from the hull and coming to the surface, and most of the rest of the rigging—including a boom, gaff, topmast, and two yards—being deposited on the lake floor to starboard of the wreck.

[3] Fishing net is wrapped around the stern, runs along the lake bed on either side of the hull, and is draped over the mainmast and forward deck.
