The Seamoth is a small one person submarine that is constructed using the Mobile Vehicle Bay. Due to the fact that it can be customized with a Moonpool and a Vehicle Modification Station, the Seamoth is very versatile.
Upon entering the Seamoth, the player's Oxygen stores will be replenished, unless the Seamoth is depleted of Energy. This enables the player to dive into deeper areas of the ocean that are not easily accessible by swimming or by using the Seaglide. However, if the Seamoth is out of energy, the oxygen within the Seamoth will slowly run out, until the point where the player is losing oxygen within the Seamoth.
The Seamoth has an energy supply that needs to be maintained by replacing the Power Cell on its back. Alternatively, the Seamoth can be charged when docked to the Cyclops or to a Moon Pool. Doing so will drain energy from the respective unit. On one full charge, the Seamoth can travel approximately 10,650 meters (106.5m per percentage of energy) before the power cell must be replaced. 1% of the submersible's energy is expended for every 18 seconds that the player remains in the vehicle, even if the player is not in motion during that time.
The Seamoth's health, separated from the player's own, will decrease if it is attacked by hostile creatures or crashed into objects (including some plants) in the environment. The damage can be repaired via the Repair tool, if the player has one. As of the Seamoth Update, once its health reaches 0%, the Seamoth will explode.
Compared to the Cyclops and the PRAWN Suit, the Seamoth is significantly faster, making it excellent for exploration. However, it is also more prone to damage, and even a fully upgraded Seamoth cannot explore the deepest biomes (That being the Inactive and Active Lava Zones).
The Seamoth's headlights can be toggled with the right mouse button on PC.
Upon entering the Seamoth, it says "Welcome Aboard Captain."
The Seamoth can be harmed or destroyed by colliding with the terrain and by surpassing the crush depth limit. Many Fauna including the: Reaper Leviathans, Bone Sharks, Crashfish, Crab Snakes and Drooping Stingers can all be considered serious threats towards the submersible. Also, large groups of Biters can attack the Seamoth, dealing minor damage.
The Seamoth produces enough forward thrust to travel at a maximum speed of about 12.7 m/s, and enough lateral thrust to travel at about 11.3 m/s. By rotating the Seamoth diagonally off-course and thrusting both forward and laterally, speeds close to 17 m/s can be attained.
While useful, this method of travel can be hazardous, since the player's field of view will be reduced in the direction of travel.
It is important to keep in mind that the Seamoth will not lose momentum when the player exits, and the player will be placed in front of the vehicle - at top speed, this can easily kill the player. Always come to a complete stop before exiting.
Upgrades and Customization Edit
The Seamoth can be customized with the Vehicle Modification Station. The console allows the Seamoth to be named and its colours changed. The console also crafts upgrade modules for the Seamoth. Up to four of these modules can be applied to the upgrade panel found on the Seamoth's left wing.
The Seamoth has a crush depth of 200 meters. 20 Meters before the player reaches the crush depth a warning will appear letting the player know that it is approaching. Below 200 meters the on-board AI will state:
"WARNING: Maximum depth reached, hull damage imminent".
At that depth the Seamoth will take hull damage at a constant rate of about 7% per second.
It is possible to increase the Seamoth's crush depth adding Pressure Compensator upgrade. These upgrades do not stack and can be further upgraded by Modification Station.
Permanently hardened chassis before collision, eliminating damage under normal conditions.
The Power Efficiency Upgrade recycles heat by-product to minimize power inefficiencies. Each module reduces power use by 15%.
The Seamoth Solar Charger is an upgrade module that enables the player to recharge their Seamoth's battery while in the sun.
Generates a localized electric field designed to ward off aggressive fauna.
A standard underwater payload delivery system adapted to fire torpedoes:
A dedicated system for detecting and displaying topographical data on the HUD
Data Bank Entry Edit
The seamoth is a one-person submersible with an independent, replaceable power cell and a fully customizable design. Most long-range mining vessels carry at least two submersibles of this class to facilitate the exploration and exploitation of water-bearing planetoids.

- The old Seamoth Pressure Compensator has the same crush depth of a Cyclops Ultra Hull Reinforcement Module. However, it is now unobtainable, having been replaced by the Pressure Compensator, and cannot be upgraded. If a player has one, it is considered a separate item from the Pressure Compensator.
- The Seamoth's AI used to occasionally say "I love it when you come inside me" instead of "Welcome aboard, Captain." This was a joke slipped in by the sounds producer, Simon Chylinski. After discussing the line with the dev team, Simon removed it as a lot of minors and families play Subnautica.
