What is the importance of lateen sail?
The lateen is believed to have been used in the Eastern Mediterranean as early as the 2nd Century ce (common ear). The effective use by the Arabs caused it's rapid spread through the Mediterranean. The lateen sail was so popular because its ability to sail into the wind. Prior to the lateen a majority of sea vessels used square sails (which one can imagine wouldn't sail into the wind very effectively). The lateen made up a majority of ship sails during the Age of Discovery (When Columbus discovered the Americas). The lateen made it possible to sail faster, farther, and more efficiently. An elite ship during the Age of Discovery was the caravel, its elite status can be attributed to how effectively it utilized the lateen sail.

Columbus used Tocanelli's data as well as ancient and medieval sources to determine his calculations and unfortunately they were grossly incorrect. Due to the exaggerated …extension of landmass eastward and his reduction in the terrestrial meridian, Columbus ended up on different islands than he meant to go to during his voyages.
Who manufactures the dolphin Sr dinghy class sailboat it is lateen rigged with a center board and no jib?
The Dolphin Sr. is not being manufactured at this time. The last boats were made around 2000 or 2001. The owner of the manufacturing rights and mold is at Lake Con…roe, Texas.

Lateen sails work in much the same way that most other triangular sails work. If the wind is behind the sail it will push the boat/ship/craft/vessel forward. But suppose t…hat the boat is at right angles to the wind. What happens then? The sail is let out on the side of the boat that away from the wind. The wind blows against the surface of the sail. It might strike the surface at an angle of, say 140o. The wind escapes from the side of the sail at its widest point, and the boat slides towards the opposite direction i.e. the direction the boat is facing, its keel preventing it from simply moving/sliding in the water in a path directly away from the wind This is a basic explanation of how a Lateen sail works. Of course, it doesn't fully explain how a boat with Lateen sails can sail almost directly into the wind! For more information, see 'Related links' below.
It depends what type of sailing ship: Modern, racing dinghies have between 1 and 3 Old, battleships like those in Pirates of the Caribbean can have 15 or more! In genera…l though, a sailing boat has the large mainsail, a smaller foresail or jib, and perhaps a large balloon-like spinnaker at the very front.
Sails catch the wind which propels the boat forward 2nd Answereer says: Previous answerer has been tricked by a trick question: IN REALITY the wind foils around the the …sail and PULLS the boat forward. A sail is nothing more than a vertical wing, providing LIFT. Should you ever have the pleasure to experience a strong puff of wind startling your becalmed craft, you will FEEL the LIFT that is provided. It's a physics thing (Aerodynamics). 3rd Answerer says: Actually, its a bit of both! When sailing "with the wind" (i.e. wind coming from straight behind the boat and hitting the sail pretty well square on) the push on the sail is transferred to the mast and boat. There's obviously a little bit of "less air pressure behind the sail" as a result, so there is some kind of "pull" going on too, but not much like this. (Air is too "runny" and will not let a significant area of low pressure form at lower speeds.) But a triangular sailed boat is pretty clever really because you don't have to sail with the wind mostly behind you - you can sail "across" the wind, and depending on the design of the sail and boat combined can get pretty close up to the point where you start to sail into the wind. Some of this force is just from the "push" from the wind on the sail, and the structure of the boom/mast transfers the push onto the frame of the boat again. But the clever bit is that the shape of the sail does indeed then form a "wing" too, just like you get on an aeroplane, and the air hitting the sail supports the shape. Air flowing around the "front" of it then moves faster than behind it so you get a lower pressure forming in front which in turn "lifts" the boat forward. (Easier to draw than put in words!) If you sail ("point up") too close the the direction the wind is coming from the sail will start to "luff" as air starts to come around the front of the sail, and pushes the front of it nearest the mast in the other way, spoiling the shape of the aerofoil wing and as a result the speed then drops off pretty sharply!
Strictly speaking, a boat's sails serve to catch the wind, propelling the boat forward. They can be adjusted in a number of ways using things like sheets, halyards, topping li…fts, cunninghams, and other lines. Sails are generally adjusted based on what direction the boat is facing relative to the wind, how windy it is, and how fast you want to go. Many small boats have two sails. The larger of these sails is generally called the mainsail. It is to the rear of the mast and is attached to the boom. In the average two-person skipper/crew setup, one of the skipper's duties is to control the mainsail. This is achieved via the main sheet, which is pulled in or let out based on how close (or far from) heading upwind the boat is. In general, the closer you are to upwind, the more the sails should be pulled in. The smaller of the two sails is generally called the jib. The crew controls the jib via the jib sheets, which are adjusted in nearly the same way as the main sheet. In addition, some small sailboats are equipped to fly a spinnaker. This sail is sometimes also called a chute because it looks like a parachute when full. The spinnaker is flown only when going downwind or nearly downwind, and is controlled by both the skipper and crew.

Europeans knew that sailing around the Cape of Good Hope would be faster than walking on the Silk Road.

Sailing is a sport that requires the changing of the rigging and rudder on a boat to change the direction and speed of the boat. The boat is moved by wind against the sails.
The sail functions as a vertical wing, channeling airflow further along one surface than the other. As the airflow re-combines, it causes what is commonly called "lift". This …pulls a vessel up & forward at the same time, due to the shape of the sail.
Trapezoidal, actually. But the square sails were called square sails. Lateen or square could be referred to as yards.
Did the invention of triangular lateen sails make it possible for ships to sail more easily into the wind?
Allegedly, the lateen sail design made it possible to sail closer into the wind. That is, less than 45 degrees from the direction the wind is blowing. No sail boat can sail di…rectly into the wind. Yet.
Triangular-shaped sails helped catch wind from the sides and rear.
