USS Polly

USS Polly is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand USS Polly rather than just read about it. In short: USS Polly (SP-690) was a United States Navy patrol vessel in commission from 1917 to 1919. After the conclusion of her Navy career, she operated in the fleet of the United States Bureau of Fisheries as USFS Curlew.

Key takeaways

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

Reference excerpt

USS Polly (SP-690) was a United States Navy patrol vessel in commission from 1917 to 1919. After the conclusion of her Navy career, she operated in the fleet of the United States Bureau of Fisheries as USFS Curlew.

Construction and early history Polly was built as the private motorboat Howmornel by the New York Yacht, Launch and Engineering Company at Morris Heights in the Bronx, New York, in 1909. She later was renamed Kakhin IV and Polly.

U.S. Navy On 14 May 1917, the U.S. Navy purchased Polly from William H. Merriman, of New Haven, Connecticut, for use as a section patrol boat during World War I. She was commissioned at Newport, Rhode Island, as USS Polly (SP-690) on 15 May 1917. Assigned to the 2nd Naval District in southern New England, Polly carried out patrol duties for the rest of World War I. Polly was stricken from the Navy List on 11 March 1919 and transferred to the United States Bureau of Fisheries on 9 September 1919.

U.S. Bureau of Fisheries The U.S. Bureau of Fisheries (BOF) renamed the vessel USFS Curlew, and, after modifying her for fisheries duty, assigned her to the BOF station at Cape Vincent, New York, for use in fish-culture work on Lake Ontario. During the summer of 1922, the Cape Vincent station installed electric lighting aboard Curlew and attached metal plates to the forward part of her hull at the waterline to protect her planking. On 24 September 1923, Curlew rescued 58 passengers from the Canadian steamboat Waubic, which had run aground in fog at Bear Point about 8 nautical miles (15 km; 9.2 mi) from Cape Vincent while making her daily run between Cape Vincent and Kingston, Ontario, Canada. During fiscal year 1928, which ran from 1 July 1927 to 30 June 1928, Curlew underwent extensive repairs and alterations and her original engine was replaced by a diesel engine. United States Department of Commerce records list Curlew as being in the Bureau of Fisheries fleet as of 30 June 1937 but not as of 30 June 1938, indicating that the Bureau retired her sometime during fiscal year 1938 (1 July 1937–30 June 1938).

Worked examples

Example 1 — a first encounter with USS Polly

Start with the simplest possible case. Write down what USS Polly 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 USS Polly 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 USS Polly 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 USS Polly

In research: USS Polly 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 USS Polly 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: USS Polly is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1909 ships, Research vessels of the United States, Ships built in Morris Heights, Bronx, so understanding it makes those chapters shorter.
In everyday life: Look for USS Polly 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.
