The Sovereign class yacht is designed to serve essentially the same function as any other ship's yacht. Like all of the new generation, it is a warp capable design intended to be capable of short and medium duration interstellar missions as well as interplanetary trips. The Yacht is capable of warp 9 in an emergency, but its normal cruise speed is warp 5, giving it the same general mission radius as a Danube class Runabout.

The ship contains a small cargo bay and transporter system, two staterooms, a shared room for the crew, plus a living area and separate flight deck. The normal crew is 2, although a single person can handle the flight controls. A third crew member cares for the guests.

There is no standard armament as such, but the yacht is capable of firing tachyon bursts [1] in an emergency and is equipped with shields for defensive purposes.

The Sovereign class yacht was seen in "Star Trek : Insurrection", where Picard used it to ferry supplies down to the Baku and Data later attacked the Son'a ship in it. The fact that it is equipped with a tachyon emitter comes from this film, while the lengths are from "The Making of Star Trek 9" by Terry J. Erdmann. The rest of the entry is speculative, and is intended to show a ship which is somewhat more advanced than the Galaxy class yacht, but does basically the same thing.
