Which items are the most profitable for convoys?

The first thing you need to do is to finish Myriam's Homestead Missions. Now you need to have 3 Land Convoys constructed AND have purchased the extra slots to carry more items in the convoys.

Make sure all the Forts are Liberated and all the districts Liberated in New York.

Now head to your ledger and purchase the following supplies from Myriam: Bear Pelts x10 - Total Cost £2400 Beaver Pelts x10 - Total Cost £1600 Deer Pelts x10 - Total Cost £1200 Total Investment - £5200

Now head to your convoys and load up the first convoy with 9 Bear Pelts going to Rhinelander's Sugar in New York. Now load the second with your last Bear Pelt and 8 Beaver Pelts, and finally your final convoy with the last 2 Beaver Pelts and 7 Deer Pelts.

You may have more of any of these pelts simply from your animal hunting in the Frontier, but lets assume for this example you only have what's purchased.

You will receive the following return on your convoys: Convoy 1 - £11,232 Convoy 2 - £7,904 Convoy 3 - £6032 Total Profit after initial Investment: +£19,968

You can repeat this every 15 minutes or so, from any ledger at any General Store to get enough money to buy anything you could possibly need in the game.

If you send a full capacity naval convoy with loaded with artillery to the Virgin Islands, you make around £1638 for each individual one. That means each convoy is £24570.
