A sailboat is a boat that uses a mainsail and jib to harness the power of the wind. Sails are made of durable, flexible and lightweight materials like polyester, mother-of-pearl or dacron. Metal winches and rods are used to facilitate the opening and closing of the sails and their reversing movements. It is the thrust produced by the bending of these materials that drives the sailboat forward.
Sailing is a popular pastime for millions of people around the world. It can be a relaxing way to spend the weekend or an exciting and thrilling weekday evening sport. It is also a professional pursuit with teams of single- and multi-person crews racing all over the globe.
Until recently, it was widely thought that sailing ships needed long keels to prevent sideways slippage (also known as leeway). However, extensive computer modeling and tank testing has shown that a keel only needs to be symmetrical to perform as well as a flat sail. This is because a smooth surface along the hull reduces resistance to motion through the water by eliminating turbulence, which dissipates energy.
Catamarans are two-hulled vessels that offer some distinct advantages over monohulls, such as a larger living area on the bridge deck that makes it easier to socialize amongst guests and provide more storage space and room for systems such as air conditioning, generators, etc. They are also faster, more comfortable and provide a more stable ride. They are also a great choice for families and groups with limited sailing experience who want to take a cruise without the need to learn how to sail first.
