Notes

The Galaxy class Yacht is essentially a large shuttle with accommodations suitable for diplomatic personnel on short duration interplanetary missions. It is unarmed, although there are defensive shields. The yacht is docked to the underside of the saucer section of the galaxy class, with access via a large roof hatch. The ship can cruise at relativistic speed, although Starfleet practice is to limit all non-critical missions to no more than 0.25 c in order to minimize time dilation effects.

The standard crew is 2 persons, with a third carried to provide care for the guests. The ship has a single deck layout, although the central area is raised in order to provide space for the impulse engine and supporting spaces beneath. It is capable of atmospheric operation and landings.

In practice, the yacht is not often used. Insystem operations are of such duration that Captains have generally preferred to use shuttles for these kinds of roles. [3]

Comments

The Galaxy class Captain's Yacht is one of those things that we never got to see on screen. All information on it comes from the TNG Tech Manual. However, the Tech Manual's sizes are way off when you compare them to scale diagrams of the ship as seen on the bottom of the saucer section and to the images of the ship on screen. I have gone with my own calculations for the sizes, but left other specifications unaltered.
