Description (Specifications)

NAFAL system spaceships are horrendously expensive, many times the annual wages of the typical worker, even on a rich world. Starcraft with jump drives are even more expensive than that. Thus, citizens who can afford to buy a personal starship, even a small one are tremendously wealthy and why would the wealthy build anything less than a Y-class Yacht or Private Vessel? As such, Y-class ships tend to be luxurious, high performance and extensively stocked with servants, bodyguards, cooks, and other service staff.

Strategy & Tactics (Doctrine)

Most Private Vessels are minimally armed and/or armored, but there are plenty of exceptions. After all, they can afford it. Heck, they can afford to specialize a ship in any fashion they like... Most often, yachts and private vessels employ escorts for defense, and if alone, they simply run when facing a hostile threat. On other hand, Q-Ships that look like yachts are not an uncommon sight.
