PENTECONTER Greek galley

The vessel depicted on this stamp I could not find a drawing of her on the internet, but she was given as a 600 BC used Greek cargo galley. On the stamp is depict a one row vessel with a ram bow. At that time the Greeks used a penteconter Greek galley for war, piracy and transport.

The penteconter, alt. spelling pentekonter and pentaconter, also transliterated as pentecontor or pentekontor (Greek: πεντηκόντορος, pentekontoros "fifty-oared"),plural penteconters was an ancient Greek galley in use since the archaic period. In an alternative meaning, the term was also used for a military commander of fifty men in ancient Greece.
The penteconters emerged in an era when there was no distinction between merchant and war ships. They were versatile, long-range ships used for sea trade, piracy and warfare, capable of transporting freight or troops. A penteconter was rowed by fifty oarsmen, arranged in a row of twenty-five on each side of the ship. A midship mast with sail could also propel the ship under favourable wind. Penteconters were long and sharp-keeled ships, hence described as long vessels (νῆες μακραί, nḗes markaí ). They typically lacked a full deck, and thus were also called unfenced vessels (ἄφρακτοι νῆες, áphraktoi nḗes).

Homer describes war ships during the Trojan War of various numbers of oars varying from twenty-oared, such as the ship that brought Chryseis back to her father, to fifty-oared, as Odysseus’ ship that had fifty men and as many as 120 men of the Boeotian ships.

According to some contemporary calculations, penteconters are believed to have been between 28 and 33 m (92 and 108 ft) long, approximately 4 m wide, and capable of reaching a top speed of 9 knots (17 km/h; 10 mph). However, modern reconstructions of penteconters, as well as other ancient ship designs such as triremes, manned by modern untrained amateurs, attained that top speed fairly easily on initial sea trials, which implies that the top speed of that type of ship in the ancient era had to be substantially higher. Ancient Greeks also used the triaconter or triacontor (τριακόντορος triakontoros), a shorter version of the penteconter with thirty oars. There is a general agreement that the trireme, the primary warship of classical antiquity, evolved from the penteconter via the bireme. The penteconter remained in use until the Hellenistic period, when it became complemented and eventually replaced by other designs, such as the lembos, the hemiolia and the liburnians.

The Akademik Kurchatov was the first of six oceanographic research ships built for the Russian Academy of Science. Little, if anything, has been overlooked in these floating laboratories. A helicopter pad is on the boat deck aft. There are two 5-ton derricks forward, and two 2-ton derricks, while at the after end are an 8-ton and a 5-ton derrick. In the forward hold 125 tons of scientific equipment can be stored, while the rocket magazine is stored aft in a similar hatch. To enable the ship to proceed at slow speeds during research operations, an active rudder of 300 h.p. is fitted; there are also two 190 h.p. bow thrust units. The ship can be driven at 4 knots with the main engines stopped. On the boat deck are two motor and two hand-propelled life-boats, a survey launch and a 25-knot personnel launch. On two powered reels forward there is 8,200 fathoms of steel wire rope for trawling and riding to a sea anchor (600 kg.). The trawl can be worked from a projecting boom at the bow or from gallows on the starboard side aft. Five small derricks with electric winches are provided for overside measurements. Push-button control is installed on the bridge. A very high standard of accommodation is provided for the 85 crew and 81 scientific staff. The ship has an operational radius of 20,000 miles at 16 knots, the maximum speed being l8'/2 knots.Main engines are two Halberstadt-M.A.N. diesels of the K6Z 57/80 type. The vessel was built in 1966 by Matthias-Thesen-Werft, at Wismar, and has three decks. She is of 5,460 tons gross, with a summer deadweight of 1,986 tons. Her dimensions are: length (o.a.) 407 ft. 6 in. (b.p.) 360 ft.; beam 55 ft. 9 in.; maximum draft 19 ft. 5in. She is a single-screw vessel.
