The Seamoth is a fast, safe mode of transport, but remember that swimming is good for your glutes and endorphin levels.File:SeamothVO.ogg

― PDA, Dialogue

The Seamoth is a small, versatile one-person submersible capable of sustained high-speed travel over considerable distances. It boasts an omnidirectional propulsion system that allows for lateral and vertical movement at relatively constant speeds no matter the vehicle's orientation.

As with the Cyclops and Prawn Suit, the Seamoth comes equipped with a locator beacon that produces an image on the HUD showing the distance of the vehicle from the player. It can be fitted with multiple upgrades and modifications that enhance performance and durability. These can be crafted in a Moonpool equipped with a Vehicle Upgrade Console.

Before the Seamoth can be constructed, its fragments must first be scanned. Several can be found in the numerous Wrecks in the Grassy Plateaus surrounding Lifepod 5, and in the Aurora.

Overview

The Seamoth is an electric vehicle and requires Energy from a Power Cell in order to function. It generates its own oxygen supply. When exiting while the vehicle is moving, the Seamoth will preserve its momentum and place the pilot behind it or in front of it. The pilot should be careful not to exit while quickly moving with dangerous creatures around, as the Seamoth may move away before the pilot can get back in, leaving them vulnerable to attack, or because the Seamoth might hit the player.

Story Spoiler
An Ion Power Cell can also be used to power it.

Controls

• Enter the Seamoth by clicking the left mouse button (LMB) when prompted on PC and Mac, or pulling the left trigger or pressing the A button on the Xbox One.
• Exit the Seamoth by pressing the E key (E) on PC and Mac, or pressing the B button on Xbox One.
• Toggle the Seamoth's headlights on or off by clicking the left mouse button (LMB) on PC and Mac, or pulling the right trigger on Xbox One.

Hazards

The Seamoth has a hull integrity readout, which will decrease if the craft is attacked by hostile creatures, crashes into objects (including some plants), is exposed to temperatures greater than 70°C or exceeds its maximum crush depth. Reaper Leviathans are able to grab the Seamoth, dealing constant damage until it explodes. The player can not exit the Seamoth when this is happening. 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.

Installing A Charged Power Cell

Outside of the Seamoth, there are panels that open. The power cell is replaced by accessing the installed unit at the rear of the craft. When selected, a menu will appear allowing the technician to choose a new power cell from inventory.

Upgrades and Customization

The Seamoth can be customized with the Vehicle Upgrade Console, which the player can use to craft upgrades and change the vehicle's name and color scheme. Upgrades can be installed and swapped via a panel on the left wing. Opening this panel reveals four slots. The Storage, Hull Reinforcement and Engine Efficiency modules are compatible with the Prawn Suit.

Depth Compensator	Increases the vehicle's maximum crush depth, enabling it to survive greater pressure. Each successive module doubles the maximum crush depth of the last. This effect does not stack. Modules Crush Depth None 200 m MK1 300 m MK2 500 m MK3 900 m
Internal Storage	Installs a 4x4 storage compartment in a position on the Seamoth corresponding to the slot used. Each additional module adds an additional storage compartment, but slots are not shared across lockers (i.e. 2 lockers cannot store 3x3 objects, even though there are more than 27 total slots). Module Position Compartment Position Upper Left Starboard Rear Top Lower Left Starboard Wing Upper Right Port Rear Top Lower Right Port Wing
Hull Reinforcement	Strengthens the chassis with a diamond lattice, increasing hull durability. Decreases collision damage by 50%; each successive module adds half the damage resistance of the last. Damage from aggressive fauna remains unchanged. Effect stacks with up to three modules. Modules Damage Reduction 1 50% 2 75% 3 87.5%
Engine Efficiency	Increases maximum battery life by recycling engine thermal waste and decreases total power consumption by 15%. Effect stacks with multiple modules. Modules Power Use Reduction 1 15% 2 30% 3 45% 4 60%
Solar Charger	Replenishes the onboard power supply by harnessing photonic energy. The charge rate is affected by the time of day and depth of water. Time of Day Charge Rate/Hr Morning (6 am-10 am) 15% Noon (10 am-2 pm) 30% Evening (2 pm-6 pm) 15% Night (6 pm-6 am) 0% Depth of Water (Noon) 0-50 m (0-164 ft) 30% 50-100 m (164-328 ft) 20% 100-150 m (328-492 ft) 10% 150-200 m (492-656 ft) 0%
Perimeter Defense System	Generates a localized electrical field to discourage and repel aggressive fauna. Has a chance of killing smaller aggressive species. Activate by pressing the assigned hotkey on PC and Mac, or by selecting the upgrade on consoles (Xbox One and PlayStation 4:Error: Invalid Button SpecifiedError: Invalid Button Specified).
Torpedo System	Standard-issue underwater payload delivery system that has been adapted to fire torpedoes. Torpedo Effect Damage Gas Poison 25/sec Vortex Immobilize 0/sec
Sonar System	Scans the topography of the surrounding terrain with sonic pulses and displays the data on the HUD. Activate by pressing the assigned hotkey on PC and Mac, or by selecting the upgrade on consoles (Xbox One and PlayStation 4:Error: Invalid Button SpecifiedError: Invalid Button Specified).

Data Bank Entry

<tabber> Seamoth=

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. Ratings: - Top Speed: 13m/s - Acceleration: 5m/s/s - Distance per power cell: 10km - Crush depth: 200m below sea level - Upgrade module slots: 4 - Dimensions: 3m x 1.5m x 1m - Persons: 1 Seamoths may be modified by installing upgrade modules to the access point mounted on the wing. These include: - Increased cargo storage - Superior power - Pressure and collision compensation - Enhanced sonar - Defensive capabilities NB These modules may only be manufactured at a moonpool outfitted with a vehicle modification station. 'The Seamoth: It goes anywhere but land.'

Trivia

• 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's AI used to occasionally say "I love it when you come inside me" instead of "Welcome aboard, Captain." This was a joke/sexual innuendo 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.
• The Seamoth bears a striking resemblance to the real-world C-Explorer 3 submersible, produced by U-Boat Worx, although the in-game Seamoth has a more streamlined appearance.
