Especially if you have children on board. You should always have an emergency float plan. A boat livery is a boathouse or dock on a lake or other body of water, where boats are let out for hire (rental), usually on an hourly, daily or weekly basis.
Boats may bepowered or sail craft or human powered like rowboats, paddleboats (pedalos) or inflatable boats. The primary use of the boats is recreational. Watercraft are water-borne vehicles including ships, boats, hovercraft and submarines.
Watercraft usually have propulsive capability (whether by sail, oar or engine) and hence are distinct from a simple device that merely floats, such as a log raft. Most watercraft would be described as either a ship or a boat.
However, there are numerous craft which many people would consider neither a ship nor a boat, such as: surfboards (when used as a paddle board),underwater robots, seaplanes, jetskis and torpedoes.
Although ships are typically larger than boats, the distinction between those two categories is not one of size per se. Ships are typically large ocean-going vessels; whereas boats are smaller, and typically travel most often on inland or coastal waters.
A rule of thumb says “a boat can fit on a ship, but a ship can’t fit on a boat”, and a ship usually has sufficient size to carry its own boats, such as lifeboats, dinghies, or runabouts. Local law and regulation may define the exact size (or the number of masts) that distinguishes a ship from a boat.
Traditionally, submarines were called “boats”, perhaps reflecting their cramped conditions: small size reduces the need for power, and thus the need to surface or snorkel for a supply of the air that runningmarine diesel engines requires; whereas, in contrast, nuclear-powered submarines’ reactors supply power without consuming air, and such craft are large, much roomier, and classed as ships in some navies.
A merchant ship is any floating craft that transports cargo for the purpose of earning revenue; in that context, a passenger ship’s “cargo” is its passengers.
The term “watercraft” (unlike such terms as aircraft or spacecraft) is rarely used to describe any individual object: rather the term serves to unify the category that ranges from jet skis to aircraft carriers. Such a vessel may be used in saltwater and freshwater; for pleasure, recreation, physical exercise, commerce, transport or military missions.
