There are seeds out there but honestly you will ruin the game for yourself. Nothing more fun than having to farm resources to build a ship and take enough supplies to explore and having no idea whats out there. I tend to have a portal at home, bring portal mats with me on me and small base building mats in the ship. Go out and build a portal to where I explore, name it and sail back home. Then I have one master portal i rename as if im dialing a location to each point I have established an outpost. Sometimes it goes wrong and i die ect. But its exciting and half the fun of the game.
