As for the dock, it really depends on the type item. It's usually pretty fair but not easy. For this this last shipment, I need to fill 4 boxes of 3 blackberries (which I barely had!), 4 boxes of 3 syrups (this is the hardest one) and 4 boxes of 38 carrots. Other items that I have seen are blue wool hats, cakes, fruits, wheat, pancakes, juice. Wheat is by far the easiest to fill. I think I have sent 2 boats off without doing the order, because it just wasn't a good fit. I have also sent off several boats only partially filled. The last boat I did, asked for juice and I don't have a juice maker, yet. Sometimes even if they ask for one item that I do not have, I will still partially fill the order if the rest of the order is fairly easy. I usually send it away if it asks for 2 or more items that I don't have or if I don't have one of the items and the other will cause me to miss better orders on the board. You have around 15 hours to fill the boat. You also have about a 3 hour wait for the boat and if you click the dock while waiting, it will tell you what items you need to prepare for. It is a good idea, to start preparing before hand. Like for this order, knowing I would need a lot of sugar cane and carrots, I started upping the amount that I had. Also I made a few batches of brown sugar to have on hands to fulfill other orders and I got started on the syrup knowing it would take the longest. Before I got the dock, I did expand storage. I think it has helped me. Hope this helps.
