A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbors or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, and some are icebreakers or salvage tugs. Early models were powered by steam engines, which were later superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours.
A scow is a smaller type of barge. Some scows are rigged as sailing scows. In the 19th and early 20th centuries, scows carried cargo in coastal waters and inland waterways, having an advantage for navigating shallow water or small harbours. Scows were in common use in the American Great Lakes and other parts of the U.S., Canada, southern England, and New Zealand. In modern times their main purpose is for recreation and racing; there are also garbage scows for aquatic transport of refuse.
A hulk is a ship that is afloat, but incapable of going to sea. Hulk may be used to describe a ship that has been launched but not completed, an abandoned wreck or shell, or to refer to a ship whose propulsion system is no longer maintained or has been removed altogether. The word hulk also may be used as a verb: a ship is "hulked" to convert it to a hulk. The verb was also applied to crews of Royal Navy ships in dock, who were sent to the receiving ship for accommodation, or "hulked". Hulks have a variety of uses such as housing, prisons, salvage pontoons, gambling sites, naval training, or cargo storage.
A Thames sailing barge is a type of commercial sailing boat once common on the River Thames in London. The flat-bottomed barges, with a shallow draught and leeboards, were perfectly adapted to the Thames Estuary, with its shallow waters and narrow tributary rivers. The larger barges were seaworthy vessels, and were the largest sailing vessel to be handled by just two men. The average size was about 120 tons and they carried 4,200 square feet (390 m2) of canvas sail in six working sails. The mainsail was loose-footed and set up with a sprit, and was brailed to the mast when not needed. It is sheeted to a horse, as is the foresail; they require no attention when tacking. The foresail is often held back by the mate to help the vessel come about more swiftly.
A jackass-barque, sometimes spelled jackass bark, is a sailing ship with three masts, of which the foremast is square-rigged and the main is partially square-rigged and partially fore-and-aft rigged (course). The mizzen mast is fore-and-aft rigged.
SS Appomattox was a wooden-hulled, American Great Lakes freighter that ran aground on Lake Michigan, off Atwater Beach off the coast of Shorewood, Wisconsin in Milwaukee County, Wisconsin, United States in 1905. On January 20, 2005 the remnants of the Appomattox were listed on the National Register of Historic Places.
Madeira was a schooner barge that sank off the coast of Minnesota in Lake Superior on November 28, 1905. A schooner barge is a type of ship that functions like a barge, in that it is towed by a steamship, but also has sails like a schooner. This type of ship evolved from wooden sailing ships that were cut down into barges and towed behind wooden steamships, a practice which originated in the late 1880s in coastal areas. This design was commonly used in the Great Lakes for transporting grain, iron ore, and other products.
Acushnet – a steel-hulled revenue cutter – was launched on 16 May 1908 at Newport News, Virginia, by the Newport News Shipbuilding and Drydock Co.; sponsored by Miss Alayce Duff; and commissioned at Baltimore on 6 November 1908. She saw service as a United States Revenue Cutter Service cutter, a U.S. Navy fleet tug, and as a U.S. Coast Guard cutter. She was taken out of service 8 January 1946.
John Payne Ltd was a shipbuilder in Bristol, England, who built coastal colliers and cargo ships, and small craft such as tugs, during the 19th and 20th centuries.
Richard Holyoke was a seagoing steam tug boat built in 1877 in Seattle, Washington and which was in service on Puget Sound and other areas of the northwest Pacific coast until 1935. The vessel was considered to be one of the most powerful tugs of its time.
R. J. Hackett was a steamer built in 1869 in Cleveland, Ohio, by Peck & Masters. When the ship was first launched, both its wide cross-section and long midships hold were unconventional. The design's clear advantages in moving cargo through the inland lakes quickly resulted in many imitators.
C.H. Wheeler was a schooner-rigged unpowered lumber barge that operated during the year 1901, making only a few voyages before it was wrecked near Yaquina Bay with the loss of one life. C.H. Wheeler was the largest vessel up to that time to reach Tillamook City and the first vessel to transport a load of lumber from Tillamook to San Francisco. The circumstances of the loss of the C.H. Wheeler were controversial and resulted in the arrest of the captain of the tug that had been towing the barge before it was wrecked.
Minnedosa was a four-masted wooden Great Lakes schooner launched in 1890. This was late in the era of sailing ships and it spent its career as a schooner barge, towed by a steam tug. It was lost with its nine crew and passengers and a heavy load of grain in a storm October 20, 1905 on Lake Huron.
The George Spencer was a wooden lake freighter that sank on along with her schooner barge Amboy on Lake Superior, near Thomasville, Cook County, Minnesota in the Mataafa Storm of 1905. On April 14, 1994, the wrecks of the Spencer and the Amboy were listed on the National Register of Historic Places.
The SS Lakeland was an early steel-hulled Great Lakes freighter that sank on December 3, 1924, into 205 feet (62 m) of water on Lake Michigan near Sturgeon Bay, Door County, Wisconsin, United States, after she sprang a leak. On July 7, 2015, the wreck of the Lakeland was added to the National Register of Historic Places.
The Amboy was a wooden schooner barge that sank along with her towing steamer, the George Spencer on Lake Superior off the coast of Schroeder, Cook County, Minnesota in the United States. In 1994 the remains of the Amboy were added to the National Register of Historic Places.
The AmboyandGeorge SpencerShipwreck Site is an archeological shipwreck site which consists of the wrecks of the wooden bulk freighter George Spencer and the wooden schooner-barge Amboy. Both vessels were wrecked during the Mataafa Storm of 1905. In 1994 the site was added to the National Register of Historic Places.
SS Selah Chamberlain was a wooden-hulled Great Lakes freighter that sank in Lake Michigan in 1886, 6 miles (10 km) off the coast of Sheboygan, Sheboygan County, Wisconsin, United States after being rammed by the steamer John Pridgeon Jr. with the loss of five lives. On January 7, 2019, the wreck of Selah Chamberlain was listed on the National Register of Historic Places, and was given the reference number 100003288. She was the first shipwreck listed on the National Register of Historic Places in 2019.
Plymouth was an American Schooner barge that sank during the Great Lakes Storm of 1913 in Lake Michigan, near St. Martins Island at the mouth of Green Bay, while she was being towed by the tug James H. Martin from Menominee, Michigan, United States to Lake Huron.
