Subnautica: Seamoth - how to upgrade? Subnautica Guide and Walkthrough

Last update: 27 March 2021

Seamoth is a small underwater vehicle that can reach places the Cyclops cannot due to its large size. Its initial specs are nothing special, though. In its basic version it's got a small crush depth. It's also completely unarmed. You'll need to invest in some upgrades for this boat.

Upgrades for the Seamoth can be made in two places: modification station and the vehicle upgrade console. You have several modifications to choose from, including: sonar, storage module, torpedo system, perimeter defense system, depth module compensator, hull reinforcement, engine efficiency module, and solar charger.

The Seamoth has four upgrade slots. You can access them at any time. You just have to find the right place on the floaters. This will open the upgrade panel, where you can install the upgrades.
