Norda

Norda 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 Norda rather than just read about it. In short: Norda is a wooden sailing vessel that was commissioned in 1928, originally used as a research vessel in Poland. It served as research vessel, fishing vessel and is now a yacht.

Key takeaways

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

Reference excerpt

Norda is a wooden sailing vessel that was commissioned in 1928, originally used as a research vessel in Poland. It served as research vessel, fishing vessel and is now a yacht.

History

Research vessel The vessel was commissioned in 1928 by MIR (Polish Fishing Institute). It was built in 1928 to order of in the Andersen Shipyard in Frederikssunde, Denmark. It was christened Ewa, inspired by the names of daughters of both Professor Michał Siedlecki and Dr Franciszek Lubecki, two distinguished scientists and maritime researches pioneers. MIR owned another vessel that was almost the same: a few months earlier they acquired another cutter Starnia, which was also used for finding new fishing grounds and fisherman’s training. Both vessels played an important role in the development of the sea fishery industry in Poland. The classical hull of the cutter, with straight bow and spoon shaped stern, was built from oak. The ship was built as a sailing vessel with an auxiliary motor. The propulsion system was composed of a two-cylinder Tuxham engine of 64-76 hp and ketch rigged gaff sails. The GRT was 29 ton and the NRT was 10 ton. The total area of the four sails was 160 m2. Under deck there was space for a crew of five, four scientists and laboratory. When already in use as research vessel, a wheel house was built on the aft deck. The cutter was commanded by Jan Lemke until 1936. In that time Ewa sailed the Baltic and was used for research expeditions organized by scientists form MIR, The Department of Economy and Organization of Fishery in Bydgoszcz, The Sea Fishery Laboratory form Hel and departments of the Scientists Laboratory of Farming from Puławy. In 1932 those institutions were united in the maritime base in Hel, which was also the home harbour or Norda at that time. Those expeditions contributed to recognition of fishing grounds at the Baltic Sea and development of polish sea biology and ichthyology. After six years of intensive exploitation Ewa had to be renovated. In 1939, during inspection at the Fishery Shipyard in Gdynia, it was ascertained that the hull had been seriously damaged (rotten) and the cutter was qualified to be destroyed. At that time Antoni Budzisz from Gdynia became interested in her. He bought the cutter from MIR and adapted her as a fishing boat. Ewa was being overhauled and the damaged parts of the hull were exchanged.

The German occupation during World War II The overhaul was unfortunately interrupted by the Second World War, but later it continued and it was finally completed in 1942. The overhaul was done in such way that the masts were cut and a more powerful motor was the only power source. The cutter, at that time named Putzig 2, was used as fishing boat with the base port in Władysławowo. Leon Budzisz was her captain. Leon was a cousin of Antoni Budzisz, who died during the war. According to Mr Jerzy Budzisz, son of Leon Budzisz, the vessel was called Anne Marie between 1941 and 1945. On March 3, 1945 the cutter was confiscated and used by a group of Germans to escape from Hel to Köln. The around 100 persons that escaped with Putzig-2 were mainly soldiers and postmen.

The swan-dance in Communist Poland In 1946, she was traced down and brought back Gdynia. The General Sea Fishery Inspectorate assigned former Ewa to The Community “Rybak”, and she was renamed to Wła – 17. Leon Budzisz became once more her captain. After Community was closed down this same Leon Budzisz bought the cutter, and used it as a fishing boat till 1955 when he had to sell her due to financial problems. The cutter was bought by The Community “Gryf”. In 1958 the next overhaul had to be made. At that time the cutter was already deprived of sailing equipment and the spoon shaped overhang on the stern. Till half of the 1980s the boat, renamed to Zag-9, was being exploited by two individual ship-owners. The base port was Gdańsk, Górki Zachodnie. Later they decided that it was not worth it to make another repair of the hull.

Worked examples

Example 1 — a first encounter with Norda

Start with the simplest possible case. Write down what Norda 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 Norda 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 Norda 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 Norda

In research: Norda 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 Norda 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: Norda is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1929 ships, Fishing in Poland, Individual sailing vessels, so understanding it makes those chapters shorter.
In everyday life: Look for Norda 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.

What is Norda in simple terms?

Norda is a wooden sailing vessel that was commissioned in 1928, originally used as a research vessel in Poland. It served as research vessel, fishing vessel and is now a yacht.

Why does Norda matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
