So, the Merchant Alliance has created a bit of a stir. I would suggest this as a possible redesign.
Having Merchant Alliance gathering quests as a primary voyage is a bit annoying and tedious. They don't feel terribly adventurous or piratey. Not really a 'voyage'. Perhaps these fetch quests could be consigned to bottle quests or events. This way they can occur in the background and don't eat up all your focus as your main voyage.
For more exciting primary voyages, I would like to recommend something like Keep Talking and Nobody Explodes. A ship is handed a series of objects to transport to a very far-away outpost in a very short time(current timers are like 6 days, which is really long). These can be special beasts and objects that create chaos on the ship, creating problems that have to be dealt with and solved occasionally. Higher tier quests require more objects to be transported, compounding the issues that can arise at once. This would be like dealing with the modules on a KTANE bomb. This would challenge crew organization and sailing skills to get there as quickly as possible.
Edit 1: An example would be free-roaming animals. Things that wander and you really don't want them getting too close to your banana storage, they might eat it. Or knock supplies on the ground.
Edit 2: We're supposed to be helping move and find rare resources. How about some kind of plant that we can put in a pot and occasionally releases bursts of hallucinogenic gas that applies drunkeness or hallucinations to players in range. You either have to deal with the effects or cure it like normal(bucket of water to the face).
