Yacht 115 (One One Five)

Most large yachts, 50 ft (15 m) (15 m) and up, are also cruisers, but their design varies greatly as they are often "one off" designs tailored to the specific needs of the buyer.The interior is often finished in wood panelling, with plenty of storage space. Cruisers are quite capable of taking on long-range passages of many thousands of miles. Such boats have a cruising speed upwards of 6 knots. This basic design is typical of the standard types produced by the major yacht-builders.
• Luxury sailing yachts
These yachts are generally 82 ft (25 m) or longer. In recent years, these yachts have evolved from fairly simple vessels with basic accommodation into sophisticated and luxurious boats. This is largely due to reduced hull-building costs brought about by the introduction of fibreglass hulls, and increased automation and "production line" techniques for yacht building, especially in Europe.
On the biggest, 130-foot-plus (40 m) luxury yachts, every modern convenience, from air conditioning to television, is found. Sailing yachts of this size are often highly automated with, for example, computer-controlled electric winches controlling the sails. Such complexity requires dedicated power-generation systems. In recent years the amount of electric equipment used on yachts has increased greatly. Even 20 years ago, it was not common for a 25-foot (7 m) yacht to have electric lighting. Now all but the smallest, most basic yachts have electric lighting, radio, and navigation aids such as Global Positioning Systems. Yachts around 33 ft (10 m) bring in comforts such as hot water, pressurised water systems, and refrigerators. Aids such as radar, echo-sounding and autopilot are common. This means that the auxiliary engine now also performs the vital function of powering an alternator to provide electrical power and to recharge the yacht's batteries. For yachts engaged on long-range cruising, wind-, water- and solar-powered generators can perform the same function.
