Dinghy

A dinghy (or dingey) is a type of small boat, often carried or towed for use as a ship's boat by a larger vessel. The term is a loanword from the Bengali ḍiṅgi, Urdu ḍīngī & Hindi ḍieṁgī. Utility dinghies are usually rowboats or have an outboard motor, but while some are rigged for sailing, they are not to be confused with sailing dinghies which are designed first and foremost for this purpose.

Dinghies usually range in length from about 2 to 6 m (6 to 20 ft). Larger auxiliary vessels are generally called tenders, pinnaces or lifeboats. Folding and take-down multi-piece (nesting) dinghies are used where space is limited. Some newer dinghies have much greater buoyancy, giving them more carrying capacity than older boats of the same size.

Dinghy is also a term given to any small cars, trucks or suvs towed behind a motor home.

On yachts shorter than 10 m (33 ft), there is usually not enough room for a reasonably sized dinghy. A dinghy is useful to avoid the need for expensive dock or slip space, so owners of small yachts compromise by carrying a small rigid dinghy or deflated inflatable, or by towing a larger dinghy. Space can be saved by storing items in containers or bags that are tied to the dinghy. Dinghies are sometimes used as lifeboats; recently self-rescue dinghies have come back into use as proactive lifeboats that can be sailed to safety.

Rigid dinghies for small yachts are very small, about 2 m (6 ⁹⁄₁₆ ft), usually with a pram (blunt) bow to get more beam (width) in a shorter length. Larger dinghies are towed and should have reserve buoyancy, an automatic bailer, and a cover to prevent them from being lost at sea. Most masters prefer a tow cable long enough to put the dinghy on the back side of the swell to prevent the dinghy from ramming the transom of the yacht.
