Mega yacht 3D model

A superyacht or megayacht is a large and luxurious pleasure vessel. There are no official or agreed upon definitions for such yachts, but these terms are regularly used to describe professionally crewed motor or sailing yachts, ranging from 40 metres (130 ft) to more than 180 metres (590 ft) in length, and sometimes include yachts as small as 24 metres (79 ft).[2]

Superyachts are often available for charter with a staff that caters to guests at a high standard of comfort. They may be designed to emphasize comfort, speed, or expedition capability. Depending on the season, superyachts may be most frequently found in the Mediterranean or the Caribbean. Many are available for charter at prices that exceed €100,000 per week. Larger examples may have more than one swimming pool; they may carry a variety of water toys, other boats, and some a helicopter.40 metresA 40-metre (130 ft) superyacht may have cabins for 10–12 guests and for a crew of a similar size. This type of yacht may be configured, as follows:[31]

Lower deck: exterior swimming platform at the stern; four (sometimes five) guest cabins with en-suite bath aft; engine room amidships; crew quarters forward.Main deck: sheltered exterior deck aft leading into the saloon; dining room and galley; entrance amidships; owner's suite forward, usually includes a study, and sometimes a second stateroom for a personal assistant/bodyguard.Upper deck: exterior deck aft, often used for outdoor dining; second saloon (often called the sky lounge); sixth stateroom will be amidships if it is not on the lower deck or part of the owner's suite; captain's cabin; bridge.Sun deck: the uppermost deck, often features a hot tub and sometimes a glass-enclosed gym (which can also be below decks or even part of the owner's suite).50 metresA 50-metre (160 ft) yacht may have one or more yacht tenders for reaching shore and other water toys which may include a speed boat or sailing boat, personal water craft, windsurfing and diving equipment and a banana boat. Such yachts have multiple screen displays and satellite communications.[31]

60 metresYachts above 60 metres (200 ft) are typically built to individual specifications, cost tens of millions of dollars, and typically have four decks above the waterline and one or two below. There is likely to be a helicopter landing platform. Apart from additional guest cabins, which are likely to include one or more VIP suites besides the owner's suite, such a yacht will have some or all of the following amenities: indoor hot tubs, sauna and steam rooms, a beauty salon, massage and other treatment rooms, a medical centre, a disco (usually the same space as the sky lounge or saloon, transformed into a dance area when furnishings are moved aside and special lighting activated), a cinema, plunge pool (possibly with a wave-maker), a playroom, and additional living areas such as a separate bar, secondary dining room, private sitting rooms or a library.[31]

Support vessel

A superyacht support vessel carries bulky items, including watercraft or a helicopter[32]Superyachts may be accompanied by a support (or shadow) vessel that carries such items as watercraft, helicopters or other large items that the yacht itself cannot readily accommodate. Such vessels range in length from 20 to 100 metres (66 to 328 ft). There are at least four manufacturers that specialize in building such vessels.[33] One 67-metre (220 ft) example included the following amenities: a helicopter deck, six guest rooms, two-story helicopter hangar with sound system, movie theater, freshwater pool, a landing craft, four each of: jet skis, kayaks, sailboats, diving and fishing gear, and water skis. For use ashore, there were reportedly a two-seater automobile, two motor scooters and two bicycles. The vessel also featured a 35-tonne (35,000 kg) crane
