Summer Bikini Beach Girls Recreate On Yacht Vessels

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.
• Racing yachts
Racing yachts try to reduce the wetted surface area, which creates drag, by keeping the hull light whilst having a deep and heavy bulb keel, allowing them to support a tall mast with a great sail area. Modern designs tend to have a very wide beam and a flat bottom, to provide buoyancy preventing an excessive heel angle. Speeds of up to 35 knots can be attained in extreme conditions. Dedicated offshore racing yachts sacrifice crew comfort for speed, having basic accommodation to reduce weight. Depending on the type of race, such a yacht may have a crew of 15 or more. Very large inshore racing yachts may have a crew of 30. At the other extreme are "single handed" races, where one person alone must control the yacht.
