Archimedes' principle, principle that states that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid. The principle applies to both floating and submerged bodies and to all fluids, i.e., liquids and gases. It explains not only the buoyancy of ships and other vessels in water but also the rise of a balloon in the air and the apparent loss of weight of objects underwater. In determining whether a given body will float in a given fluid, both weight and volume must be considered; that is, the relative density, or weight per unit of volume, of the body compared to the fluid determines the buoyant force. If the body is less dense than the fluid, it will float or, in the case of a balloon, it will rise. If the body is denser than the fluid, it will sink. Relative density also determines the proportion of a floating body that will be submerged in a fluid. If the body is two thirds as dense as the fluid, then two thirds of its volume will be submerged, displacing in the process a volume of fluid whose weight is equal to the entire weight of the body. In the case of a submerged body, the apparent weight of the body is equal to its weight in air less the weight of an equal volume of fluid. The fluid most often encountered in applications of Archimedes' principle is water, and the specific gravity of a substance is a convenient measure of its relative density compared to water. In calculating the buoyant force on a body, however, one must also take into account the shape and position of the body. A steel rowboat placed on end into the water will sink because the density of steel is much greater than that of water. However, in its normal, keel-down position, the effective volume of the boat includes all the air inside it, so that its average density is then less than that of water, and as a result it will float.
What do you call the metal object on the dock where you tie up a boat?
It's usually called a cleat, generally a horn cleat.
Which companies offer a corporate discount for sailing trips?
Sailing trip discounts are available to everyone and there are many to choose from such as sailing events, they offer many different packages each with great saving and discounts for corporate clients.
When was the first America's Cup held?
The ship America, beat out a fleet of Britain's finest in 1851. The trophy was given to the captain and the race was later renamed, The America's Cup. The first real race for this trophy, under the new name was in 1870 with 14 vessels.
When does a sailboat give way?
Any powered vessel must give way to a boat under sail power. The main reason is maneuverability as the sail boat cannot reverse its sails in order to stop. Since the sailboat is dependent entirely on the wind for power it simply just cannot go in any direction like a powered craft can.
Which side of a vessel has a red light at night?
Red marks the Port or left side. (Green is Starboard or the right-hand side.)
Port

Why were the longboats good for sailing in shallow waters?
The Viking longboat had a very shallow-draft hull. This meant they could raid far up rivers.
What is the fore-and-aft carry?
The two-man fore-and-aft carry is used to transport a conscious or unconscious casualty and is the preferred two-man carry for moving a casualty for a long distance.
How long does it take to cross the Atlantic ocean in a sailboat?
From where to where? To sail the biennial Transpac Yacht Race from Los Angeles to Honolulu, winning boats commonly make the 2500+ mile journey in around 7 days. On the other hand, depending on winds and route taken, the return trip can take anywhere from 3 weeks on up. Fair winds and following seas to you.
How long does it take a boat to sail to Cabo San Lucas from San Diego?
It depends on how fast you sail, where you stop, and weather conditions.
Where did titanic set sail for New York?
At the New York City harbor, close to where the Statue of Liberty is
"Abaft" or "aft" would be correct, depending on usage/context. Also "Astern".
Basic structural parts of the ship?
Here is a Summary of the movie Titanic. So a rich girl named Rose goes on titanic with her mother and finance who is also rich. Then a poor artistsaves her life after she almost fell off the back of the ship. Soon disaster strikes and don't leave Jack (the penniless artiest) side. They both go in the water which is about freezing and Jack dies and Rose says i will never let go and she then is saved but misses Jack. At the end of the movie she either dies or has a dream and sees jack and all those such as Mr.Andrew,Mr.Murdoch, The Captain, Cora and many more people. 1500 lives went in the sea that night and all are there at the ending. I think she dies because she sees all those who died that night.
Where did the sea dog Francis Drake sailed along the coast of?
He sailed the Pacific Ocean.
Other Info:
Born: 1540
Died: 1596
He was an Englishman Explorer, and was the first Englishman to sail the world.
Hope this was helpful!
What is the name of the 3-masted sailing vessel invented by the Portuguese?
A caravel is a ship with 3 masts. To see a photo of a delightful model of a caravel, click on the Related Link.
Did Magellan sail on the Trinidad?
The flagship of Ferdinand Magellan's expedition, the caravel Trinidad, was captured by the Portuguese in the Maluku Islands (Moluccas) and sailed to Ternate Island, where the sails and rigging were removed. The vessel eventually sank there after a storm broke it up.
The HMS Victory is a large, wooden ship that was built in England in the years between 1759 and 1765. The ship was built at the Old Single Dock in the Chatham Dockyard.
Did Columbus want to find India by sailing west instead of east?
Yes, which would have confirmed his belief in a shorter trade route to "The East" :(
How did Australians get to America?
The first Europeans to arrive in Australia for permanent settlement were the convicts who were transported from England to Australia. They were fully cared for and were not left to fend for themselves. They were sheltered and fed, but made to work hard. If they shirked their duties, they could be flogged or have their rations reduced. The marines and officers who watched over the convicts had enough rations and livestock to keep going until farms could be established.
Hunting was carried out to a small degree. Europeans did not initially develop a taste for native Australian wildlife, and the colony almost starved until it had its first successful barley crop, and the 3rd Fleet arrived.
Who was the sailor who in 1895 was the first person to sail around the world alone?
The first person to sail around the world alone was Joshua Slocum.He set sail aboard his home-built craft,the Spray,in 1898 and completed the 73,600 kilometres in 1,158 days-stopping several times on the way.In 1969,Robin Knox Johnston became the first person to sail around the world alone non-stop.He took 312 days and 1 hour to travel 48,167 kilometres in his yacht Suhaili.
