Sailing
Beginning of paper
Ever since early sailors used square sails to help add speed to their oars, the sailboat has become increasingly more complex. The type of construction varied with the availability of materials. Wood was a common material, but was not available in areas like Lake Titicaca where the boats and sails both were constructed of reeds from the shoreline. ....
Middle of paper ....alize that a sailboat may not sail at the wind and certain angles to the wind. This is called the luff zone. The efficiency of a boat in upwind situations can be determined by the angle at which the boat no longer gains forward momentum. The first sailboats had fixed sails and heavy improperly balanced ships. They were very inefficient and slow.
