Ratlines And Sail Handling Lines
Ratlines () are lengths of thin line tied between the shrouds of a sailing ship to form a ladder. Found on all square-rigged ships, whose crews must go aloft to stow the square sails, they also appear on larger fore-and-aft rigged vessels to aid in repairs aloft or conduct a lookout from above. Rat-boards Rat-boards are lower courses in a ratline, often made of slats of wood (batten A batten is most commonly a strip of solid material, historically wood but can also be of plastic, metal, or fiberglass. Battens are variously used in construction, sailing, and other fields. In the lighting industry, battens refer to linea ...s) for support where the distance between shrouds is greatest. In some instances holes in these slats guide and organise low-tension lines between the deck and the rig. Knotting See also * Footrope References {{Sail Types Sailing rigs and rigging ...

Mir(22)
''Mir'' (, ; ) was a space station operated in low Earth orbit from 1986 to 2001, first by the Soviet Union and later by the Russia, Russian Federation. ''Mir'' was the first modular space station and was assembled in orbit from 1986 to 1996. It had a greater mass than any previous spacecraft. At the time it was the largest artificial satellite in orbit, succeeded by the International Space Station (ISS) after ''Mir'''s orbital decay, orbit decayed. The station served as a microgravity laboratory , research laboratory in which crews conducted experiments in biology, human biology, physics, astronomy, meteorology, and spacecraft systems with a goal of developing technologies required for permanent occupation of Outer space, space. ''Mir'' was the first continuously inhabited long-term research station in orbit and held the record for the longest continuous human presence in space at 3,644 days, until it was surpassed by the ISS on 23 October 2010. It holds the recor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
