The Grassy Plateau close by is littered with Seamoth fragments. Now you have the tools, but you still need the know-how. Once you have the bay, take it into the ocean and deploy it, where it will unfold into a small platform that floats on the water and can be stood on, equipped with a screen that allows you to select what you want it to build.

Mobile Vehicle Bay: Titanium ingot x1, lubricant x1, power cell x1.

This is the easiest stage of all, as the Mobile Vehicle Bay is built with components that can either be found or built early on without too much trouble. | Joel Franey/USGamer, Unknown Worlds Entertainment How to Build the Mobile Vehicle Bay The Mobile Vehicle Bay can be used to make your Seamoth, as well as other vehicles later in the game. To do this you'll need to build the Mobile Vehicle Bay in your fabricator, find broken fragments of the Seamoth spread about the world and scan them for a blueprint, and finally acquire the resources needed to construct that Seamoth. There's no intact Seamoth anywhere to be found in Planet 4546B, meaning you'll have to build one. The Seamoth can also be customised and modified later on by building a Moonpool and Vehicle Upgrade Console, including the addition of a torpedo launcher. The Seamoth is a small, one-person submarine that moves faster than the Seaglide and provides a steady supply of oxygen to anybody inside it, meaning you don't have to go up for air at all, a huge benefit.
