You can become Shipmates with other Captains by offering them an Accord for them to accept. If they do, you become Shipmates.
Being Shipmates comes with certain benefits - Reinforcements and Galleons travel faster between your Havens.
To form Brotherhoods, build a Brethren Court. Your Envoy will report new offers and inform you every time a Brotherhood has been formed or terminated.
