Reference excerpt

USFS Crane was an American fishery patrol vessel that operated in the waters of the Territory of Alaska. She was in commission in the United States Bureau of Fisheries (BOF) fleet from 1928 to 1940. She then served as US FWS Crane in the fleet of the Fish and Wildlife Service from 1940 to 1960. After a brief stint in the fleet of the Alaska Department of Fish and Game during 1960, she was sold into private service, at various times named Crane, Brapo, Fishing 5, Belle, and Patricia during the 1960s and 1970s and then again Crane since 1978. She remained in service as of 2020.

Bureau of Fisheries

Construction and characteristics Coolidge & H. C. Hanson designed Crane and J. C. Johnson Brothers constructed her at Port Blakely, Washington. She was launched on 19 April 1928, quickly completed fitting-out, was commissioned into the U.S. Bureau of Fisheries (BOF) fleet as USFS Crane, and was ready for service by May 1928. She cost US$60,000 and R. L. Cole served as the BOF inspector responsible for managing her construction. Crane was designed along the same lines as a fish-packing vessel and, at 92 feet (28.0 m) long and 134 gross register tons, was considered "massive" for her patrol role. She was of sturdy construction. She was framed entirely in Port Orford cedar, with 12-by-12-inch (30 by 30 cm) sawn frames on 18-inch (46 cm) centers spaced 6 inches (15 cm) apart. She had 8.5-by-9.5-inch (22 by 24 cm) deck beams, a 5-by-27-inch (13 by 69 cm) shelf timber, and a triple kelson made of 30 inches (76 cm) of solid wood. She had 3-inch (7.6 cm) fir planking and a 4-inch (10 cm) skin, and her hull was sheathed with ironbark. Washington Iron Works of Seattle, Washington, provided her 200-horsepower (150 kW) Washington direct-reversing Estep full diesel engine. Her electrical system included a 110-volt type B6H 112.5 ampere hour Edison nickel-iron-alkaline storage battery.

Operational history Crane departed Seattle, Washington, in May 1928 to head north for her first season as a BOF patrol vessel in Alaskan waters. She established her annual pattern of operations, which involved conducting salmon fishery patrols off the Alaska Peninsula each summer, inspecting salmon-spawning waterways in Southeast Alaska each autumn, and spending each winter at Seattle to undergo repairs and overhaul. She also routinely operated as a transport vessel, for example regularly carrying seasonal employees and supplies between Seattle and the BOF station in the Naknek River region on Alaska's Bristol Bay coast. Over the years, Crane also performed other duties. On 25 October 1928, she was among several BOF vessels tasked to assist in enforcing the provisions of the Northern Pacific Halibut Act of 1924, joining United States Navy ships and most of the rest of the BOF's Alaska Territory fleet in protecting populations of Pacific halibut in the Bering Sea and North Pacific Ocean, with her crew granted all powers of search and seizure in accordance with the act. She also added seasonal patrols of the waters of Washington and the Alaska Territory to her duties to protect sea otter populations and migrating herds of fur seals. In July and August 1931, the BOF's "Pribilof tender," the cargo liner USFS Penguin, was pulled off her duty of supplying transportation to, from, and between the Pribilof Islands in the Bering Sea to transport the Commissioner of Fisheries and other officials on an inspection tour of Alaska fisheries. During these months, Crane substituted for Penguin on the passenger and freight runs to, from, and within the Pribilofs. During the winter of 1933–1934, Crane and the BOF fishery patrol vessel USFS Scoter underwent a particularly significant restoration at Seattle thanks to a special allotment of funds by the Public Works Administration. After the completion of the renovations, Crane and Scoter deployed to Southeast Alaska to take part in a project funded by the Civil Works Administration in which they helped clear and improve salmon-spawning streams, and by 22 February 1934 the 200 temporary employees involved had cleared log jams and other obstructions from a combined total of 802 miles (1,291 km) of waterways in 325 streams. During a maritime strike on the United States West Coast that lasted from mid-November 1936 to 4 February 1937, Crane supported the United States Post Office Department by transporting the United States Mail from Seattle to Juneau, Territory of Alaska; on one voyage alone, she carried 750 sacks of mail. In 1938, Crane towed the BOF fishery patrol vessel USFS Brant from Ketchikan, Territory of Alaska, to Seattle for repairs after Brant suffered extensive damage when she ran aground on 15 July 1938. In the spring of 1939, Crane hauled cement and towed a barge carrying building materials from Washington to Southeast Alaska for a BOF Division of Scientific Inquiry construction project at Little Port Walter in Port Walter, Territory of Alaska. While transiting the Inside Passage on 21 May 1939, Crane struck a rock in Grenville Channel on the coast of British Columbia, Canada. She suffered keel damage, and was drydocked for a few days at Ketchikan for repairs.

Fish and Wildlife Service In 1939, the BOF was transferred from the United States Department of Commerce to the United States Department of the Interior, and on 30 June 1940, it was merged with the Interior Department's Division of Biological Survey to form the new Fish and Wildlife Service (FWS), an element of the Interior Department. The vessel thus became part of the FWS fleet as US FWS Crane. Little information is available about Crane's career in the Fish and Wildlife fleet, although as late as 1953 she occasionally substituted for the "Pribilof tender" – a responsibility the Fish and Wildlife Service assumed from the Bureau of Fisheries in 1940 – which by 1953 was the cargo liner US FWS Penguin II. During the late 1950s, the Fish and Wildlife Service, which had become the United States Fish and Wildlife Service as part of a major reorganization in 1956, based Crane at Seattle and used her for management purposes. Alaska became a state on 3 January 1959, and, like other states, assumed the responsibility for fishery protection within its waters. The FWS accordingly began to transfer its Alaska fishery patrol vessels to the State of Alaska, and it transferred Crane to the Alaska Department of Fish and Game on 11 April 1960.

Worked examples

Example 1 — a first encounter with USFS Crane

Start with the simplest possible case. Write down what USFS Crane claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 USFS Crane 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 USFS Crane 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 USFS Crane

In research
USFS Crane appears in mathematics 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 USFS Crane 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
USFS Crane is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1928 ships, Fishery protection vessels, Fishing ships of the United States, so understanding it makes those chapters shorter.
In everyday life
Look for USFS Crane 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.
