Dinghy

A dinghy (or dingey) is a type of small boat, often carried or towed for use as a lifeboat or tender 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 sailing. Dinghies' main use is transfers from larger boats, especially when the larger boat can't dock at a suitably-sized port or marina.

In modern Spacer language, a Dinghy is usually any type of small spacecraft with very limited range and smaller than 50 meters. It is a term not very common within Union space. Spacecraft of these type are generally referred to as Shuttles or even more commonly as D xx.
(D 10, D 20 , D 30 , D 40 etc) But is a common term among spacers, especially Non Union spacers.
