AFAIK traits only apply to the ship they are serving on, but I would like to point out that traits are mostly explained in the manual in Appendix 6. Some things are not explained
OFFICER CHARACTERISTICS
Speed enthusiast: This officer will get that extra knot of speed out of his ship, especially
if new. (Not Explained: Chance to overtax engines and lose 1 knot of speed)
ROF enthusiast: This officer will get his crew to improve ROF, at the cost of a slight
increase in the risk of flash fires, as he is prone to overlook safety measures in the quest
for higher ROF. (+10)
Gunnery expert: This officer will improve the gunnery of his ship. (+10)
Torpedo expert: This officer will improve torpedo firing of his ship.
Disciplinarian: This officer goes by the book. His crew will improve relatively fast, but
attention to rules and regulations will stop the crew from becoming really good.
Music lover: This officer will put much effort into improving the performance of the
ship’s band, which can have its advantages and disadvantages.
Sportsman: This officer loves sport, and will put much effort into the physical fitness of
his crew. (Not Explained:This is to the detriment of crew training)
Lucky: This officer will somehow evade many critical hits to his ship.
Aggressive: This officer will take a more aggressive stance than most of his colleagues.
Timid: This officer will take a more careful stance than most of his colleagues.
Well connected: This officer has connections in high circles. He will be more costly to
remove or reassign. (Not Explained, will also promote faster)
Wily: This officer is a master of evasive tactics. He will reduce the chance of his ship
being hit.
Poor Admin: Ships under this officer are more likely to miss signals or get lost in battle.
Poor shiphandler: More likely to get into collisions or other mishaps.
Loose cannon: You never know what this officer will be up to. He may perform brilliantly
or poorly, and may get into all kinds of trouble. (This is just random, but he will make suggestions to implement special training/remove cautious debuff)
Good administrator: Reduces maintenance cost of his ship.
No connections: This officer lacks connections or patrons, and will get promoted more
slowly.
