Key takeaways

  • USCGC Lotus belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect USCGC Lotus to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of USCGC Lotus from memory before moving on to harder problems.

Reference excerpt

USAMP Colonel Albert Todd was a steel-hulled ship built for service in the U.S. Army as a mine planter. She was launched in 1920. The ship was transferred to the U.S. Lighthouse Service, and recommissioned as USLHT Lotus in 1921. When the Lighthouse Service became part of the U.S. Coast Guard in 1939, she was redesignated USCGC Lotus and was given the pennant number WAGL-229. During most of her government career her primary mission was to maintain and supply aids to navigation including buoys, lighthouses, and lightships. During World War II, when the Coast Guard was subject to U.S. Navy orders, she also maintained antisubmarine nets at a number of ports. Lotus was sold to private interests in 1947. The ship was never Federally documented, and her whereabouts and activities are unknown until she was reported in the Miami River in 1956. She sank at her moorings and spent years sitting on the bottom of the river. She was refloated, towed into the Atlantic, and sunk in 1971. The wreck is now a recreational diving site.

Construction and characteristics

In early July 1918 the Newton Engineering Company and Coddington Engineering Company, both of Milwaukee, Wisconsin, were awarded a contract for nine mine planters as joint contractors. Upon the award of the contract, Newton Engineering purchased all the assets of Coddington Engineering and changed its name to Fabricated Ship Corporation. Thus the nine ships, including Colonel Albert Todd, were built by Fabricated Ship. On the U.S. government side, the contract was executed by the US Army Quartermaster Corps, which was responsible for all Army shipbuilding, for eventual use by the Army Coast Artillery Corps. The ship's hull and superstructure was built of steel plates riveted together. She was 172 ft 6 in (52.58 m) long overall, and 159 feet 6 inches (48.62 m) long on her waterline. She had a beam of 32 feet (9.8 m). Her light draft was 9 feet (2.7 m), and her maximum draft was 11 feet 6 inches (3.51 m). The ship's maximum displacement was 1,130 tons. Her gross register tons was 704 and her net register tons was 138. The ship had two propellers which were driven by two Allis Chalmers compound, inverted, reciprocating steam engines. The indicated horsepower of these engines was 1,040. Steam for the engines was produced by two oil-fired boilers. Her maximum speed was 11 knots. Her fuel oil tanks had a capacity of 35,000 US gallons (130,000 L). Her unrefueld range at 10 knots was 1,800 miles. Colonel Albert Todd was the seventh of the nine mine planters completed by Fabricated Ship. She was launched on 31 January 1920. Her original cost was $540,000. The ship's original namesake was Colonel Albert Todd, of the US Army's Coast Artillery Corps. In 1908 he became commander of Fort Totten and the Eastern Artillery District of New York.

Service history

US Army service (1920–1921)

Colonel Albert Todd sailed from Milwaukee for New York on 17 October 1920. While en route, the ship was ordered to Hoboken, New Jersey to have a radio set installed. She was assigned call sign WYBI. The ship stopped at Montreal and Halifax on her way. Consideration was given to assigning the ship to the coastal defenses in Puget Sound, but this was ultimately rejected in favor of a series of postings in the New York area. She was assigned to Fort Wood, and later Fort Totten. During her Army career she had a crew of seven officers and 20 men. The Army decommissioned Colonel Albert Todd on 6 October 1921 after less than a year of service. The rapid demobilization at the end of World War I led to a global glut of ships of all types, both civilian and military. The ship's mine planting equipment was removed and stored at Fort Wood for later use.

US Lighthouse Service (1921–1939)

On 7 October 1921, the War Department gave the Lighthouse Service three of the nine mine planters built by Fabricated Ship, including Colonel Albert Todd. These and three more sisterships given to the Lighthouse Service, were designated the Speedwell class. Substantial modifications were required to convert these ships into lighthouse tenders. Colonel Albert Todd was sent to the Lighthouse Service depot on Staten Island for this work. The forecastle was rounded and the anchor raised so that they would not foul buoys the ship was maintaining. A new steel deck was placed forward to allow the ship to handle heavy buoys. A more robust forward derrick, capable of hoisting 20 tons, and related steam-powered winches were installed. A new refrigeration plant was installed, and the crew quarters were rearranged. Converting Colonel Albert Todd cost $45,710.

The ship was renamed USLHT Lotus. She was the third vessel of that name in the service. She was commissioned in 1924 and assigned to the 2nd Lighthouse District, with her homeport at Boston. She replaced USLHT Mayflower there. Her complement in 1924 was 6 officers and 23 men. Lotus was assigned the signal letters GVMH. Her duties included delivering fuel, supplies, and personnel to lighthouses and lightships, towing lightships to and from port, and placing, replacing, and maintaining buoys. This last activity was made more difficult by the severe ice conditions which prevailed along the New England coast which damaged, sank, and carried away buoys. Louts' kerosene tanks held 15,000 US gallons (57,000 L) and her potable water tanks held 54,000 US gallons (200,000 L) for replenishing lighthouses and lightships. In 1936 her radio equipment was upgraded to include a radiotelephone capability. Her regular duties were interrupted periodically by a number of search and rescue missions. For example, on 11 August 1937, Lotus towed the disabled schooner Anna Sophia to safely at Boston. In December 1931 Lotus towed the wrecked USLHT Shrub to Staten Island for extensive repairs. In 1939 Lotus and USLHT Hibiscus played a small part in the rescue of crew members from the sunken submarine Squalus, placing mooring buoys for the rescue fleet working the scene.

Worked examples

Example 1 — a first encounter with USCGC Lotus

Start with the simplest possible case. Write down what USCGC Lotus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to USCGC Lotus before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about USCGC Lotus ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of USCGC Lotus

In research
USCGC Lotus appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses USCGC Lotus in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
USCGC Lotus is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1920 ships, Mine planters of the United States Army, Ships built in Milwaukee, so understanding it makes those chapters shorter.
In everyday life
Look for USCGC Lotus outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
