RV Onaway

RV Onaway 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 RV Onaway rather than just read about it. In short: RV Onaway (LT358) was a fisheries research vessel that was operated by the Ministry of Agriculture, Fisheries and Food (United Kingdom) - Directorate of Fisheries, now known as the Centre for Environment, Fisheries and Aquaculture Science (Cefas) between 1930 and 1960.

Reference excerpt

RV Onaway (LT358) was a fisheries research vessel that was operated by the Ministry of Agriculture, Fisheries and Food (United Kingdom) - Directorate of Fisheries, now known as the Centre for Environment, Fisheries and Aquaculture Science (Cefas) between 1930 and 1960. She was briefly requisitioned by the Admiralty, to serve as a Boom Defence Tender during World War II (between 1939 and 1945), but returned to Ministry service in 1946. In 1960 the RV Onaway was replaced by the RV Tellina.

Construction In 1928 large crowds witnessed the launch of the motor fishing bauldie Onaway from the boatbuilding yard of Walter Reekie, Anstruther, Scotland. She was built to the order of Mr William, W Carstairs of Cellardyke and was a sister ship of the Winaway, a 53 ft long steam drifter. Onaway was fitted with a 48 hp semi-diesel engine and special design of steam boiler and capstan. Miss Jessie Watson of Cellardyke, sister of the skipper performed the christening ceremony.

Service as a fisheries research vessel In 1930 Onaway was purchased by the Ministry of Agriculture, Fisheries and Food (United Kingdom). The RV Onaway (LT358) was in service with MAFF from December 1930 until March 1960, during which time she participated in 209 separate research campaigns. During the 1930s she was largely confined to inshore coastal waters of the southern North Sea including East Anglia, the Thames estuary, southern bight and Straits of Dover. Most of her early efforts were dedicated to the surveying of herring and sprat, but also plankton sampling and characterizing hydrology. After World War II, RV Onaway ventured further afield with regular sampling voyages to Cornwall and throughout the English Channel (Sussex to South Cornwall) focused on pilchard/sardine investigations, although continuing to participate in surveys of North Sea herring and sprat. In the 1950s she was used as a platform for large-scale tagging programmes targeting North Sea sole, crab, rays, herring and whiting. Between 1952 and 1959 she conducted annual surveys to characterize scallop populations in the English Channel. In March 1959 the RV Onaway was used to carry out surveys of colliery waste dumping sites off the northeast coast of England.

Service during World War II In 1939 the RV Onaway was requisitioned by the Admiralty, to serve as a Boom Defence Tender. The primary function of a Boom Defence Vessel was to lay and maintain steel anti-torpedo or anti-submarine nets. Nets could be laid around an individual ship at anchor, or around harbors or other anchorages. In January 1942 Onaway was listed among many similar Boom Defence Vessels allocated to the Scapa Flow Auxiliary Patrol (Orkney). Specifically, Onaway is listed as being "at Macduff (Aberdeenshire) refitting - to complete 14 Jan”. Following return from Admiralty service in 1946, the RV Onaway was immediately lengthened by 10 ft. and her engine changed from a 40 hp semi-diesel to a 120 hp diesel, with the result that her speed was increased from 5 to 9.5 knots.

Worked examples

Example 1 — a first encounter with RV Onaway

Start with the simplest possible case. Write down what RV Onaway 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 RV Onaway 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 RV Onaway 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 RV Onaway

In research: RV Onaway 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 RV Onaway 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: RV Onaway is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1928 ships, Research vessels of the United Kingdom, Ships of the Centre for Environment, Fisheries and Aquaculture Science, so understanding it makes those chapters shorter.
In everyday life: Look for RV Onaway 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.
