Human or Compact?
The two civilizations exist in the same universe (i.e. same fictional physics) and have some contact, but shipbuilding traditions differ. Hani ships have half a dozen crew, human ships have hundreds, Kif have thousands. They also differ in sustainable acceleration, armaments, ...
Early or Late?
Faded Sun is in the same setting as the historically earlier books. FS has a slightly different look-and-feel. (Note: Foreigner doesn't fit into the history, Morgaine probably does but it doesn't have ships.)
The vanes can not just "pulse" to slow an incoming vessel down, they can also "pulse" to accelerate a ship. There are some clues in Hellburner, early riders have no vanes so they cannot outrun their own ordnance, while a carrier can. Late model riders, as in Downbelow Station, obviously can keep up with a maneuvering carrier.
Problem with that: The braking pulses are mentioned all the time, the acceleration pulses are not clearly mentioned. Explanation: Incoming ships are faster than outgoing ships, and their pulses are more time-critical. An incoming ship rushes towards the inner system, and outgoing ship rushes towards the void. The stations don't worry if that pulse isn't on schedule. Also a case of Early Installment Weirdness (tvtropes link), compare again DS and HB.
Ships do not have to reach very high velocities to jump, they have to clear the vincinity of the station. The first clue is the threat of the Pride to cycle her vanes while docked, thereby blowing herself and the station. The second clue is how ships jumping in "dirty" areas take along debris. Since we all know that even asteroid belts are quite empty, they must grab matter over a very large radius.
Problem with that: The Pride wouldn't have taken the station into FTL. Explanation: You need some outgoing velocity and some distance from the gravity well to go interstellar, otherwise the ship is sucked into the sun of the starting system, with messy results.
