The Seamoth is a small one-person submarine that can be constructed using the Mobile Vehicle Bay. It is a versatile Vehicle that can travel at high speeds underwater, and can be customized with a Vehicle Upgrade Console at a Moonpool.
The player can enter the Seamoth with, or /. Once inside, the player can maneuver the Seamoth using the same controls as swimming, or press or to exit the Seamoth. The player can toggle the Seamoth's headlights on or off with or .
The Seamoth requires Energy from a Power Cell in order to function. On one full charge, the Seamoth can travel approximately 10,650 meters (106.5m per percentage of energy) before running out of Energy. To recharge the Seamoth, the player can replace the Power Cell on its back or dock it at a Moonpool or Cyclops (draining energy from the Seabase or Cyclops to recharge the Seamoth's Power Cell).
The Seamoth generates its own Oxygen supply as long as it has Energy (this does not consume any of its Energy). When the player enters a Seamoth that has Energy, their oxygen is fully replenished. This enables the player to dive into deeper areas of the ocean that are not easily accessible by swimming or by using the Seaglide.
Compared to the Cyclops and the Prawn Suit, the Seamoth is significantly faster and more agile, making it excellent for exploration. However, it is more prone to damage, and even a fully upgraded Seamoth cannot go deep enough to explore the deepest biomes (such as the Inactive Lava Zone and Lava Lakes).
Upon entering the Seamoth, its AI says "Welcome Aboard Captain."
The Seamoth has its own Health percentage which will decrease if it is attacked by hostile creatures, crashed into objects (including some plants) or crushed by pressure resulting from diving below its crush depth. The player can repair this damage with the Repair Tool. Once the Seamoth's health reaches 0%, it will explode.
The acidic brine in the Lost River deals periodic damage to the Seamoth.
If the Seamoth is in an area with a temperature greater than 70°C, it will begin to gradually take 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.
When exited, the Seamoth will preserve its momentum and place the player behind it. The player should be careful not to exit the Seamoth while quickly moving with dangerous creatures around, as the Seamoth may move away from the player before the player can get back in, leaving them vulnerable to attack.
Upgrades and Customization
The Seamoth can be customized with the Vehicle Upgrade Console. 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 Depth Module 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 Engine Efficiency Module 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:

Data Bank Entry
The seamoth is a one-person vehicle with an independent, replaceable power cell fitted in the rear and a fully customizable design. Low power, multi-directional thrusters enable it to function equally well in sea or space environments.
Most long-range vessels carry at least two vehicles of this class to facilitate the exploration and exploitation of small astronomical bodies, however they can also be fabricated at a standard mobile vehicle bay.
Seamoths may be modified by installing upgrade modules to the access point mounted on the wing. These include:
NB These modules may only be manufactured at a moonpool outfitted with a vehicle modification station.

- The old Seamoth Pressure Compensator (Depth Module) has the same crush depth of a Cyclops Ultra Hull Reinforcement Module. However, it is now unobtainable, having been replaced by the Depth Module, and cannot be upgraded. If a player has one, it is considered a separate item from the Pressure Compensator.
- The Seamoth is also suitable for use in space.
- 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.
