Hello everyone and today I'll be showing you all how and where to exactly upgrade your ship. To sum it up easily you'll need to be doing the quests/missions at the outpost. Once you run out of quests the Penguin Bay NPC will have a quest for you that involves you upgrading your ship license. You'll need diamonds for this , once you bring the diamonds back you'll be awarded with a new license and a ton of new quests. Now return to your ship computer and you should get a command to upgrade your ship. And it's as easy as that. Keep doing the quests/missions at the outpost and you'll eventually end up with the biggest ship.
