Panama Canal

The Panamá Canal (Spanish: Canal de Panamá) is a 48-mile (77 km) ship canal in Panama that connects the Atlantic Ocean (via the Caribbean Sea) to the Pacific Ocean. The canal cuts across the Isthmus of Panama and is a key conduit for international maritime trade. There are locks at each end to lift ships up to Gatun Lake, an artificial lake created to reduce the amount of excavation work required for the canal, 26 metres (85 ft) above sea level. The current locks are 33.5 metres (110 ft) wide. A third, wider lane of locks is currently under construction and is due to open in 2016.

France began work on the canal in 1881, but had to stop because of engineering problems and high mortality due to disease. The United States took over the project in 1904, and took a decade to complete the canal, which was officially opened on August 15, 1914. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduced the time for ships to travel between the Atlantic and Pacific Oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan. The shorter, faster, and safer route to the U.S. West Coast and to nations in and around the Pacific Ocean allowed those places to become more integrated with the world economy.

Caribbean

The Caribbean (/ˌkærᵻˈbiːən/ or /kəˈrɪbiən/; Spanish: Caribe; Dutch:  Caraïben ; Caribbean Hindustani: कैरिबियन (Kairibiyana); French: Caraïbe or more commonly Antilles) is a region that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean), and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America.

Situated largely on the Caribbean Plate, the region comprises more than 700 islands, islets, reefs, and cays. (See the list.) These islands generally form island arcs that delineate the eastern and northern edges of the Caribbean Sea. The Caribbean islands, consisting of the Greater Antilles on the north and the Lesser Antilles on the south and east (including the Leeward Antilles), are part of the somewhat larger West Indies grouping, which also includes the Lucayan Archipelago (comprising The Bahamas and Turks and Caicos Islands) north of the Greater Antilles and Caribbean Sea. In a wider sense, the mainland countries of Belize, Venezuela, Guyana, Suriname, and French Guiana are also included.

Canal

Canals and navigations are human-made channels for water. In the vernacular both are referred to as 'canals'. The main difference between them is that a navigation parallels a river and shares its drainage basin, while a canal cuts across a drainage divide.

Types of artificial waterways

A navigation is a series of channels that run roughly parallel to the valley and stream bed of an unimproved river. A navigation always shares the drainage basin of the river. A vessel uses the calm parts of the river itself as well as improvements, traversing the same changes in height.

A true canal is a channel that cuts across a drainage divide, making a navigable channel connecting two different drainage basins.

Most commercially important canals of the first half of the 19th-century were a little of each, using rivers in long stretches, and divide crossing canals in others. This is true for many canals still in use.

Structures used in artificial waterways

Both navigations and canals use engineered structures to improve navigation:

Panama

Coordinates: 9°N 80°W / 9°N 80°W / 9; -80

Panama (ⁱ/ˈpænəmɑː/ PAN-ə-mah; Spanish: Panamá [panaˈma]), officially called the Republic of Panama (Spanish: República de Panamá), is a country in Central America situated between North and South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean to the north and the Pacific Ocean to the south. The capital and largest city is Panama City, whose metropolitan area is home to nearly half of the country's 3.9 million people.

Panama was inhabited by several indigenous tribes prior to settlement by the Spanish in the 16th century. Panama broke away from Spain in 1821 and joined a union of Nueva Granada, Ecuador, and Venezuela named the Republic of Gran Colombia. When Gran Colombia dissolved in 1831, Panama and Nueva Granada remained joined, eventually becoming the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the Panama Canal to be built by the U.S. Army Corps of Engineers between 1904 and 1914. In 1977, an agreement was signed for the total transfer of the Canal from the United States to Panama by the end of the 20th century, which culminated on 31 December 1999.

MS Zuiderdam

MS Zuiderdam /ˈzaɪdərdæm/ is a Vista class cruise ship owned and operated by Holland America Line (HAL). It is the lead ship of the Vista class vessels, so named for the extensive use of glass in their superstructure, and is sister to three other HAL ships, Oosterdam, Westerdam, and Noordam. The prefixes of the four ships' names represent the four directions of the compass in Dutch.

The ship shares similar exterior dimensions with Carnival Cruise Lines' and Costa Cruises' Spirit Class. Cunard Line's Queen Victoria is an enlarged version of the same design, as is HAL's Signature Class.

As with all Vista-class ships, Zuiderdam is equipped with a diesel-electric power plant and an Azipod propulsion system, and eighty-five percent of her staterooms have ocean views and sixty-seven percent have verandahs. Her art collection carries a Venetian theme throughout the ship; the most dazzling features figures in the time of Carnival in Venice, created by Daniel Ogier.

Service History

Zuiderdam was christened by American broadcaster Joan Lunden at Port Everglades on December 14, 2002. Between October to April, Zuiderdam largely runs a southern Caribbean itinerary which includes a half-transit of the Panama Canal through the Gatun Locks. From May to September, the vessel travels to Alaska.
