Aft Deck Of RV Sikuliaq
This list of ship directions provides succinct definitions for terms applying to spatial orientation in a marine environment or location on a vessel, such as ''fore'', ''aft'', ''astern'', ''aboard'', or ''topside''. Terms * Abaft (preposition): at or toward the stern of a ship, or further back from a location, e.g. "the mizzenmast is abaft the mainmast". * Aboard: onto or within a ship, or in a group. * Above: a higher deck of the ship. * Aft: toward or at the stern. To the purist, this is an adverb (e.g. "he walked aft"), with the adjective being "after" (e.g. "the after mooring cleat"), but that distinction is becoming blurred in some modern usage. * Adrift: floating in the water without propulsion. * Aground: resting on the shore or wedged against the sea floor. * Ahull: with sails furled and helm lashed alee. * Alee: on or toward the lee (the downwind side). * Aloft: the stacks, masts, rigging, or other area above the highest solid structure. * Amidships: near the middle ...

RV Alpha Helix
A recreational vehicle, often abbreviated as RV, is a motor vehicle or trailer that includes living quarters designed for accommodation. Types of RVs include motorhomes, campervans, coaches, caravans (also known as travel trailers and campers), fifth-wheel trailers, popup campers, and truck campers. Typical amenities of an RV include a kitchen, a bathroom, and one or more beds. RVs can range from utilitarian – containing only sleeping quarters and basic cooking facilities – to luxurious, with features like air conditioning (AC), water heaters, televisions and satellite receivers, and quartz countertops. Types RVs can be either trailers that are towed by vehicles or vehicles that can be driven themselves. Most RVs have one level, but there are also some with two levels. To save space while traveling, larger RVs often have slide-outs or canopies that open up when parked. RVs that can be driven can be categorized "motorhomes", which will have the engine in front, wherea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridge Of The RV Sikuliaq
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge, dating from the 13th century BC, in the Peloponnese is one of the oldest arch bridges in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the word ''bridge' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panama Canal
The Panama Canal () is an artificial waterway in Panama that connects the Caribbean Sea with the Pacific Ocean. It cuts across the narrowest point of the Isthmus of Panama, and is a Channel (geography), conduit for maritime trade between the Atlantic and Pacific Oceans. Lock (water navigation), Locks at each end lift ships up to Gatun Lake, an artificial fresh water lake Above mean sea level, above sea level, created by damming the Chagres River and Lake Alajuela to reduce the amount of excavation work required for the canal. Locks then lower the ships at the other end. An average of of fresh water is used in a single passing of a ship. The canal is threatened by low water levels during droughts. The Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous route around the southernmost tip of South America via the Drake Passage, the Strait of Magellan or the Beagle Channel.

KRBD
KRBD is a non-commercial radio station in Ketchikan, Alaska, broadcasting on 105.3 FM. The station airs public radio programming from the National Public Radio network, the BBC World Service, and is a member of CoastAlaska. KRBD also airs some locally originated programming. As with many radio stations, the name is an abbreviation. In this case, RBD is short for "Rainbird," which is one of the mascots of Ketchikan. (Ketchikan averages about 160 inches of rainfall each year.) The station's first broadcast, on May 22, 1976, opened with the song, "The Fool," by Quicksilver Messenger Service on volunteer Tom Miller's show, "Odds and Ends." At that time, the station had seven licensed volunteers, each one covering a day of the week, and each one responsible for recruiting more volunteers. At first, the station operated out of a single apartment space on the first floor of the 10-story Marine View Building. Its 10-watt transmitter broadcast mostly to listeners within a few miles o ...

Icebreaker
An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom. For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened hull, an ice-clearing shape, and the power to push through sea ice. Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The bending strength of sea ice is low enough that the ice breaks usually without noticeable change in the vessel's trim. In cases of very thick ice, an icebreaker can drive its bow onto the ice to break it under the weight of the ship. A buildup of broken ice in front of a ship can slow it down much more than the breaking of the ice itself, so icebreakers have a specially designed hull ...

Azimuth Thruster
An azimuth thruster is a configuration of marine propellers placed in pods that can be rotated to any horizontal angle (azimuth), making a rudder redundant. These give ships better maneuverability than a fixed propeller and rudder system. Types of azimuth thrusters There are two major variants, based on the location of the motor: # Mechanical transmission, which connects a motor inside the ship to the outboard unit by gearing. The motor may be diesel or diesel-electric. Depending on the shaft arrangement, mechanical azimuth thrusters are divided into L-drive and Z-drive. An L-drive thruster has a vertical input shaft and a horizontal output shaft with one right-angle gear. A Z-drive thruster has a horizontal input shaft, a vertical shaft in the rotating column and a horizontal output shaft, with two right-angle gears. # Electrical transmission, more commonly called pods, where an electric motor is fitted in the pod itself, connected directly to the propeller without ...

V16 Engine
A V16 engine is a sixteen-cylinder Internal combustion engine#Reciprocating engines, piston engine where two banks of eight cylinders are arranged in a V engine, V configuration around a common crankshaft. V16 engines are less common than engines with fewer cylinders, such as V8 and V12 engines. Each bank of a V16 engine can be thought of as a straight-eight engine, straight-eight, a design that can be inherently engine balance, balanced. Most V16 engines have a 45° bank angle. The first use of a V16 engine was in the 1910 Antoinette VII experimental aircraft, followed by several cars in the 1930s. Today, the most common applications for V16 engines are railroad locomotives, marine craft, and stationary power generators. Automotive applications Production cars The first production car to use a V16 engine was the Cadillac V-16, introduced in January 1930. The Cadillac V16 engine was initially produced with a displacement of , overhead valve engine, OHV and a V-angle of 45 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
