I was initially thinking this would be a Merchant mission, but maybe it could apply to any faction.
The idea is that you'd need 2 boats. One would carry cargo. This cargo would be rendered on deck and cannot be moved. It would restrict access to that ship's cannons (but not stop access entirely - just make it difficult to get to them).
The 2nd ship would be the escort.
The mission is to get the cargo from point A to point B.
Other crews on the server would be aware that this cargo is being moved (not sure how)
If completed, both crews get credit. If the escort ship is sunk but the cargo arrives, both crews get credit.
If the cargo ship is sunk in PvP - the sinking crew gets some kind of reward
