Sorry, I explained myself very badly.

Admirals CAN receive movement bonus. In fact fleet moved long distances in ITW, because the default points was high (90) and they had a high bonus (200).

In my case, the problem is the limit. I'd like to make much higher the difference between movements in land and movements by sea. But with those limitations is not possible.

@Re Berengario I

How do you give traits to captains? I tried to do it, but I didn't succeed.
I tried to put different terms in character (in export_descr_character_traits): all, general, named_character, family. In any case the captain fulfilling the requirements got the trait. Only in case it was a family member.
