Sunk Yachts

Day sailing yachts are usually small, at under 20 ft (6 m) in length. Sometimes called dinghies, they often have a retractable keel, centerboard, or daggerboard. Most day sailing yachts do not have a cabin, as they are designed for hourly or daily use and not for overnight journeys. At best they may have a 'cubby', where the front part of the hull has a raised solid roof to provide a place to store equipment or to offer basic shelter from wind or spray.
• Weekender yachts
Weekender yachts are slightly larger, at under 30 ft (9.5 m) in length. They often have twin keels or lifting keels such as in trailer sailers. This allows them to operate in shallow waters, and if needed "dry out"—become beached as the tide falls. The hull shape (or twin-keel layout) allows the boat to sit upright when there is no water. Such boats are designed to undertake short journeys, rarely lasting more than 2 or 3 days (hence their name). In coastal areas, long trips may be undertaken in a series of short hops. Weekenders usually have only a simple cabin, often consisting of a single "saloon" with bedspace for two to three people. Clever use of ergonomics allows space in the saloon for a galley (kitchen), seating, and navigation equipment. There is limited space for stores of water and food. Most are single-masted "Bermuda sloops" (not to be confused with the type of traditional Bermudian ship known as a Bermuda sloop), with a single foresail of the jib or genoa type and a single mainsail (one variation of the aforementioned Bermuda rig). Some are gaff rigged. The smallest of this type, generally called pocket yachts or pocket cruisers, and trailer sailers can be transported on special trailers.
Cruising yachts Cruising yachts are by the far the most common yacht in private use, making up most of the 25 to 45 ft (7 to 14 m) range. These vessels can be quite complex in design, as they need a balance between docile handling qualities, interior space, good light-wind performance and on-board comfort. The huge range of such craft, from dozens of builders worldwide, makes it hard to give a single illustrative description. However, most favour a teardrop-planform hull, with a wide, flat bottom and deep single-fin keel to give good stability. Most are single-masted Bermuda rigged sloops, with a single fore-sail of the jib or Genoa type and a single mainsail. Spinnaker sails, in various sizes, are often supplied for down-wind use. These types are often chosen as family vessels, especially those in the 26 to 40-foot (8 to 12 m) range. Such a vessel will usually have many cabins below deck. Typically there will be three double-berth cabins; a single large saloon with galley, seating and navigation equipment; and a "head" consisting of a toilet and shower-room.
