Electronic Gyro Compass
Due to the earth’s magnetic field, there is a difference between the actual north and the north which is indicated on the ship’s magnetic compass. The difference can be as big as 13 degrees east. The earth’s magnetic field is also constantly in motion, so small changes occur over the years. The main compass used for navigation on board the

To Anchor the Ship
When anchoring a ship, the Captain takes the following into consideration: the depth of the water, if the water is too deep the anchor might drag. The type of bottom that will best hold the anchor. Not close to navigation hazards and as far away from other ships as possible. Do not anchor in harbor traffic lanes and choose the area with the weakest winds and currents. Find a place with a lot of navigational aids (landmarks, etc.) to monitor the ship’s position. The Ms Rotterdam has 2 anchors forward and 1 astern. The forward anchors each weigh 8 tons.

Contrary to popular belief the “Pink Panther” is not the Inspector Clouseau character made famous by actor Peter Sellers, but a large and valuable fictitious diamond. It bears that name because the flaw at its center, when viewed closely, is said to resemble a leaping pink panther.

The Role of Art in African Society
The multiple roles that art plays in African communities are as diverse as their forms of patronage.
Social Role: One of the most important functions of African art is distinctly social. In fulfilling this role, it frequently depicts women as mothers, usually nursing or cradling their young. Men, on the other hand, are often presented both as elders, the traditional community leaders, and as successful warriors.
Political Role: Political control is another major concern displayed through art in
Economic Role: Art in
Historical Role: An important historical role is also fulfilled in African art through its memorialization of important persons and events. In the powerful kingdom of Benin in Nigeria, elaborate relief plaques cast in bronze similarly carried images of important persons and events of the past, including battle scenes and religious ceremonies.

What Is Seawater?
Seawater is a dilute solution of several salts resulting from weathering and erosion of rocks. The salinity of seawater is expressed in terms of total dissolved salts in parts per thousand parts of water. Salinity varies from nearly zero in continental waters to about 41 parts per 1,000 in the Red Sea, a region of high evaporation, and more than 150 parts per 1,000 in the
Traveling Around the World
Any traveler circling the globe in a westward direction lengthens the day by 1 hour for every 15° of longitude traveled because the traveler is following the apparent motion of the sun; by the time he or she has traveled completely around the world, the traveler is one full day ahead of the people who have remained at the starting place of the trip. Similarly, going eastward, a traveler arrives a day behind. Close to the 180th meridian, nearly in the middle of the
of land and of civilization in the region, navigators going westward add a day to their calendars (for example, the day after February 11 would be February 13), and navigators going eastward drop a day from their calendars to correct for this gain or loss of time. The date line is curved eastward around Siberia, westward around the Aleutian Islands, and eastward around the
The Global Positioning System (GPS)
The Global positioning system (GPS) is a navigation system using 24 Earth-orbiting artificial satellites. Satellite navigation, like celestial navigation, works on the principle that if the navigator knows the exact location of a celestial body and can measure a relationship between the craft and the body, the navigator can calculate the craft’s position. In celestial navigation, this relationship takes the form of a celestial body’s altitude above the horizon.

The Bulbous Bow of a Ship
The bulbous bow of a ship increases the hull efficiency and reduces fuel costs. The bulb puts the bow wave further forward. The actual beginning of the bow of the ship will be at the trough of the bow wave, thus the bow does not need to push against a ‘wall of water’. The bulb stem also has a favorable effect on the wave system around the ship. The ideal situation is one where the ship cuts through the waves, whilst generating no waves by itself; for every wave that is created by the ship is lost energy.
Speedometer
Accurate speedometers came into popular use in the latter half of the 19th century. Until this time, most sailors estimated their speed with a chip log, a float affixed to a rope knotted at intervals of 47.25 feet, 14.4 meters. Navigators threw the float off the boat and counted the knots as they hit the water. The navigators timed their count, using a 28-second sandglass to ensure consistency. The number of knots that ran out in 28 seconds equaled the boat’s speed in nautical miles.
Sand Waves
A type of ground surface, this is sand which forms a wave type structure on the bottom of the sea or water body due to the tidal and current activity.
Latitude and Longitude
Latitude and Longitude is a system of geometrical coordinates used in designating the location of places on the surface of the earth. Latitude, which gives the location of a place north or south of the equator, is expressed by angular measurements ranging from 0° at the equator to 90° at the poles. Longitude, the location of a place east or west of a north-south line called the prime meridian, is measured in angles ranging from 0° at the prime meridian to 180° at the International Date Line.

Echo Sounder
This is an electronic depth sounder that sends a signal down and times how long the signal takes to rebound. The longer the delay, the deeper the water. Regular depth soundings help the navigator avoid straying into dangerous, shallow water. They also can help the navigator locate the craft’s position on a chart with relatively good accuracy because many nautical charts show water depth at regular intervals.

Mombasa, The Republic of Kenya
Mombasa is the second largest city in Kenya and the center of the coastal tourism industry. In Kiswahili it is called Kisiwa ya Mvita, which means "Island of War", due to the many changes in its ownership. The city has a population of around 900,000 and is located on Mombasa Island, which is separated from the mainland by two creeks; Tudor Creek and Killindini Harbor. The island is connected to the mainland to the north by a bridge, to the south by ferry and to the west by a causeway along which runs the Uganda Railway. The port serves both Kenya and countries of the interior linking them to the Indian Ocean. The Muslim Miji Kenda/Swahili people mainly occupy the town but over the centuries there have been many immigrants from the countries of the Middle East and Indian sub-continent. More recent immigrants are peoples from the interior of Kenya brought to the area by opportunities to work in the tourist industry. Traditional dress for the Swahili women is a brightly colored, printed cotton sheet called a kanga, which may have inspirational slogans printed on it, and a type of black headdress and veil called a bui bui. Men wear a type of sarong, which is colored in bright bands, called a kikoy. There are several places to visit in Mombasa; Fort Jesus, build by the Portuguese and the Old Town, which is by now in bad need of repair but still shows plenty of examples of the old Arab architecture.
The Republic of Kenya is located in east Africa and lies astride the equator. It is bordered by Somalia on the east, the Indian Ocean on the southeast, Tanzania on the south, Lake Victoria (Victoria Nyanza) on the southwest, Uganda on the west, Sudan on the northwest, and Ethiopia on the north. The country is made up of several geographical regions. The first is a narrow, coastal strip that is low lying except for the Taita Hills in the south. The second, an inland region of bush-covered plains, constitutes most of the country’s land area. In the northwest, straddling Lake Turkana and the Kulal Mountains are high-lying scrublands. In the southwest are the fertile grasslands and forests of the Kenya highlands. In the west is the Great Rift Valley, an irregular depression that cuts through west Kenya from north to south in two branches. It is also the location of some of the country’s highest mountains, including Mount Kenya (17,058 feet, 5,199 meters high). People of African descent make up about 97% of the population; they are divided into about 40 ethnic groups, of which the Bantu-speaking Kikuyu, Luhya, Kalenjin, Kamba, and Gusii and the Nilotic-speaking Luo are predominant. Small numbers of persons of Indian, Pakistani, and European descent live in the interior, and there are some Arabs along the coast. The official languages are Swahili and English although many indigenous languages are also spoken. About two-thirds of the population is Christian, while a quarter follows traditional religious beliefs; the remaining are Muslim or Hindu.
Mombasa has a warm, tropical climate. Winter months are slightly warmer than summer. The amount of rainfall depends essentially on the season. The rainiest months are April and May, while in January to February the rainfall is minimal. The average precipitation in April is around 4.7 inches (11.9cm). In meteorology, precipitation (also known as one of the classes of hydrometeors, which are atmospheric water phenomena) is any product of the condensation of atmospheric water vapour that is deposited on the earth's surface.
The Bantu language of Kiswahili (abbreviated to Swahili) is the official language of Kenya. There do exist many different verbal dialects of the language, based on the location on the town, but written Swahili is generally universal to that of eastern Africa. It originated on the east coast of Africa over 1,000 years ago and has since incorporated words from Arabic, Portuguese, Indian, German and English.

Victoria, Seychelles
The Seychelles is a group of about 115 islands that lie 990 miles (1600 kilometers) off the coast of east Africa. The three central islands - Mahé, Praslin and La Digue - are granite, while the outlying islands are coral atolls. Unlike most similar islands, the Seychelles are not volcanic - they seem to be the peaks of a huge underwater plateau that fell off the edge of India about 65 million years ago. The islands are rich in vegetation, but most of it is either coconut palms or casuarinas. The Seychelles is home to the extremely rare giant coco de mer palm. In high, remote areas you might also find the insect-eating pitcher plant, as well as a veritable bouquet of orchids, bougainvilleas, hibiscuses, gardenias and frangipani. Victoria, on the island of Mahé, is one of the smallest capital cities in the world and the only major port in the Seychelles. It is also the only town in the country - every other settlement is a village. The courthouse and main post office in the center of town have been untouched since colonial times, but the streets emanating from the center have been rebuilt over the past 20 years, giving the town a clean and modern look. There are a few old houses and shops in the city center, giving the town a unique character. Victoria’s Botanical Gardens are highly recommended for short and shady walks among a variety of native and introduced trees. The Seychelles are known for their beautiful beaches and serene waters, perfect for snorkeling or a relaxing day on the sand.
Nobody lived on the Seychelles until the 17th century. In 1609, a British East India ship made landfall, and in the next few years, shiploads of pirates moved their operations to the Indian Ocean from the Caribbean and used the islands as their base. In 1742 the governor of Mauritius sent a ship to check out the islands. The ship’s captain named the main island after his governor and laid the way for the French to claim the islands 12 years later. In 1770 the first load of French settlers and slaves arrived on the island and started growing spices, cassava, sugar cane, coffee, sweet potatoes and maize, as well as harvesting the giant tortoise. By the end of the 18th century, the islands were looking pretty choice and the British were taking an interest. The governor at the time lowered the French flag and gave in when attack looked imminent, but the British sailed on and the flag was raised again. This happened 12 times until 1814, when Britain took charge of the Seychelles after the Napoleonic Wars. French, however, remained the main language and French culture lived on. English and French are the two official languages of the Seychelles; however, Creole (a dialect of French) was made a semi-official language in 1981. Most Seychellois will conduct business in French, speak English to the tourists and Creole at home.

Early History of Oman
Muscat, Oman
An important trading port between the east and west since the 1st century CE, Muscat is both the capital and largest city of the Sultanate of Oman. Located on the Arabian Sea it was ruled by various factions including both the Persians and the Portuguese Empire. Its power as a regional military force extends back to the 18th century. Since the ascension of its current Sultan, Qaboos bin Said, in 1970 Muscat has developed rapidly leading to a stimulated economy and a diverse, multi-ethnic population. The landscape is dominated by the Western Al Hajar Mountains and the economy is driven mostly by petroleum, trade and its port facilities. Ethnically, Muscat has always been a hybrid of people not native to the Arabian Peninsula. Hindu temples existed in Muscat as far back as 1760 and Christianity is thought to have been spread by the Portuguese as early as the beginning of the 16th century. Although Arabic is the predominant language of the city, English, Balochi, Swahili and South Asian languages such as Hindi and Urdu are spoken. Islam is the predominant religion in the city and while non-Muslims are allowed to practice their religion, they are discouraged from proselytizing publicly or distributing religious literature. This religious tolerance is indicated by the presence of two Hindu temples, several Christian churches located in a multi-denominational compound in Ruwi, including the Catholic church of Saints Peter and Paul. On July 23, 1970, Sultan Qaboos bin Said staged a bloodless coup in the Salalah palace with the assistance of the British, took over from his father as ruler, and put an end to the Dhofar uprising which had threatened the area since 1962. He consolidated the differing tribal territories in an attempt to end to the interior's isolation from Muscat.
Port Sultan is located on the coast of the Gulf of Oman, on the Tropic of Cancer, 250km S of the Strait of Hormuz on the Indian Ocean coast of the Arabian Peninsula. The city lies on the Arabian Sea along the Gulf of Oman and is in the proximity of the strategic Straits of Hormuz. Low-lying white buildings typify most of Muscat's urban landscape, while the port-district of Muttrah, with its corniche (Arabic: cliff) and harbor, form the north-eastern periphery of the city. Muscat's economy is dominated by trade, petroleum and porting.
Salalah, Oman
Modern Oman is home to the Port of Salalah; its location makes it a major entry point to India, the Middle East, and Africa. Salalah is the capital and seat of the governor or Wali of the southern Omani province of Dhofar. It is the second largest town in the Sultanate of Oman and a traditional stronghold and birthplace of the Sultan Qaboos bin Said. The Sultan traditionally lives in Salalah rather than in Muscat, the capital and largest city in Oman. Salalah, despite lying in the Arabian desert, enjoys a temperate climate through most of the year. The town is also subjected to the southeast monsoons between late June and early September. Visitors from across the Persian Gulf flock to Salalah to enjoy the monsoons and avoid the harsh heat faced by the rest of the region during the same period. Also in this period, the town’s population nearly doubles. The town has a large expatriate community, mainly from India, as well as a private Indian school, known as Indian School Salalah. The city of Salalah is known as the perfume capital of Arabia. The city is a popular destination for tourism due to the natural attractions of the Jabal al Qar mountains and abundant stands of frankincense trees lining mountain stream courses. Around the city and into the mountains the countryside is lush and green with the vegetation supporting herds of cattle. Salalah is a city of antiquity, boasting the ruins of a palace reputed to have belonged to the Queen of Sheba and the resting place of the biblical prophet Job in the nearby Jabal al Qar. It is also the alleged resting place of Nabi Imran, father of the Virgin Mary.
