How Yachts Are Made in Factories? (Mega Factories Video)
A yacht is a sail or power vessel used for pleasure, cruising, or racing. There is no standard definition, so the term applies to such vessels that have a cabin with amenities that accommodate overnight use. To be termed a yacht, as opposed to a boat, such a pleasure vessel is likely to be at least 33 feet (10 m) in length and may have been judged to have good aesthetic qualities.
Originally, all yachts were made of wood, using a wooden keel and ribs, clad with planks. These materials were supplanted with iron or steel in steam yachts. In the 1960s fiberglass became a prevalent material. These materials and others continue in use. Whereas yachts of 79 feet (24 m) and below may be constructed of fiberglass, larger yachts are more likely to be constructed of steel, aluminum or composite fiber-reinforced plastic.
Wood construction, using conventional planks over ribs continues. Hard-chined boats made with plywood is an infrequent technique. Whereas yachts made with the WEST system—plies of wood strips, soaked in epoxy and applied over the boat frame—provide a durable, lightweight and robust hull.
Metal hulls from steel or aluminum offer the opportunity for welding components to a completely watertight hull. Both metals are vulnerable to damage due to electrolysis. Steel is easy to repair in boatyards around the world, whereas aluminum is a much lighter material.
