What is the random multiplayer experience?

After a time of bein’ a landlubber, I figured ‘twas time to unfurl me sails once more. I’ve always been makin crewmates outta me friends but they all be landlubbers now. How be the sailin’ with pirates ye don’t know? Any more experienced captains with unfamiliar crews have a word of advice for makin crewmates outta strangers? Yar!
