A landyacht is a term used to describe luxurious recreational vehicles and is an informal term for large automobiles.
Other descriptors of these cars include 'slab', 'luxobarge', 'lead sled', or 'yank tank'. These terms refer to the largest full-sized cars made by North American and German auto manufacturers from the 1950s through the 1990s.
Land yachts are essentially large cars and recreational vehicles (RVs) compared to yachts that ride on land, evoking the relative size, maneuverability, and luxury of the water vessel. An extravagant RV with two floors designed for entertainment and super yacht lifestyle was valued at $3 million. The Airstream luxury recreational vehicle manufactureer uses "Land Yacht" as a model name.

In automobiles, the term is most commonly applied to the large American cars of the pre-oil crisis era. Cars of this era remain known for size, large and powerful V8 engines, and an emphasis on ride comfort at the expense of handling. Features commonly found in landyachts include very generous exterior proportions, somewhat vague steering, and a soft ride. Consumers purchased these large cars for a many reasons and practicality was usually one of them. One of the largest production sedans were the 1974–1976 Cadillac Fleetwood 75 sedans that reached 252.2 in (6,406 mm) in length and weighed 5,500–6,100 lb (2,500–2,800 kg). Many landyacht-type cars are four-door sedans or hardtop (no "B" pillar) body styles, but large coupes, convertibles, and station wagons were available.
In American English, a dock is technically synonymous with pier or wharf—any human-made structure in the water intended for people to be on. However, in modern use, pier is generally used to refer to structures originally intended for industrial use, such as seafood processing or shipping, and more recently for cruise ships, and dock is used for most everything else, often with a qualifier, such as ferry dock, swimming dock, ore dock and others. However, pier is also commonly used to refer to wooden or metal structures that extend into the ocean from beaches and are used, for the most part, to accommodate fishing in the ocean without using a boat.
In American English, the term for the water area between piers is "slip".
In the cottage country of Canada and the United States, a dock is a wooden platform built over water, with one end secured to the shore. The platform is used for the boarding and offloading of small boats.
This area is a good place to park your landyacht.
