The more quests you do for a team the more your power goes up with that team. You can eventually sign with that team, giving you access to their ports, crew loyal to that clan, etc. Other clans will have objectives to sink you, and may received rewards for sinking ships of another clan.
If you aren't apart of a clan, you either have a good/bad score (reputation). This is based on how many good/bad ships you sink, how many people you save/vs capture, etc.
