Schooner

A schooner (IPA: [ˈskuːnə]) is a kind of sailing vessel characterized by the use of fore-and-aft sails on two or more masts. Schooners were first used by the Dutch in the 16th or 17th century, and more developed in North America from the time of the American Revolution.

The schooner sail-plan has two or more masts with the forward mast being shorter or the similar height as the rear masts. Most conventionally rigged schooners are gaff rigged, occasionally carrying a squ are top sail on the foremast and occasionally, in addition, a square fore-course (together with the gaff foresail). Schooners that carry square sails are called square-topsail schooners. Modern schooners might be Marconi or Bermuda rigged. Some schooner yachts are Bermudan rig on the mainmast and gaff-rigged on the foremast. A stay-sail schooner has no foresail, but in its place carries and main-stay sail between the masts besides the fore-staysail ahead of the foremast. A stay-sail or gaff-topsail schooner can carry a fisherman (a four sided fore and aft sail) above the main-stay sail or foresail, or a triangular mule. Multi masted stay-sail schooners generally carried a mule above each stay sail apart from the fore-stay sail. Gaff-rigged schooners usually carry a triangular fore-and-aft topsail above the gaff sail on the major topmast and sometimes also on the fore topmast (see illustration), called a gaff-topsail schooner. A gaff-rigged schooner that is not made for carrying one or more gaff topsails is sometimes called a 'bare-headed or bald-headed' schooner. A schooner which has no bowsprit is known as a 'knockabout' schooner.

Motorboat

A motorboat usually speaking is a vessel other than a sailboat or personal watercraft, propelled by an interior combustion engine driving a jet or a propeller. However, the International Regulations for Preventing Collisions at Sea defines that any boat propelled by machinery. A speedboat is a small motorboat intended to move quickly, used in races, for pulling water skiers, as patrol boats, and as fast-moving armed attack vessels by the military. Even inflatable boats with a motor attached which may be serving as a high speed patrol boat or as a plodding walker dingy providing transport to and from a mooring buoy are strictly classified as motorboats.
There are three well-liked variations of power plants: inboard, inboard/outboard, and outboard. If the engine is installed within the boat, it's called a power plant; if it's a detachable module attached to the boat, it's normally known as an outboard motor.

An outboard motor is installed on the rear of a boat and contains the inner combustion engine, the gear decrease (Transmission), and the propeller.An inboard/outboard contains a hybrid of a power plant and an outboard, where the interior combustion engine is contained inboard and the gear reduction and propeller are outside.

A purely inboard boat contains everything apart from a shaft and a propeller inside the vessel. We have two configurations of an inboard, v-drive and straight drive. A direct drive has the power plant mounted close to the middle of the boat with the propeller shaft straight out the back, where a v-drive has the power plant mounted in the back of the boat facing backwards having the shaft go towards the front of the boat than making a 'V' towards the rear.

Yacht

The term luxuriousness yacht refers to a very expensive privately owned yacht which is professionally crewed. Also known as a super-yacht or a mega-yacht, a luxury yacht may be moreover a sailing or motor yacht.

The New York Yacht Club hosted many early luxury sailing yacht events at Newport, Rhode Island, throughout the Gilded Age.
More recently, over the last decade or two, there has been an increase in the number and fame of large private luxury yachts. Luxury yachts are mainly bountiful in the Mediterranean and Caribbean Seas, although increasingly luxury yachts are cruising in more remote areas of the world. With the increase in demand for luxury yachts there has been an increase custom boat building companies and yacht contract brokers.
